Abstract:
This article describes the features of voltage regulation in electrical networks of 35, 110, 220 kV. The structural diagram of the 35/10/0.4 kV network is presented. The paper also describes the adaptive automatic voltage regulation system which allows regulating the voltage taking into account the actual voltage values at the consumers’ inputs. The structural diagram of the adaptive automatic voltage regulation system in the 0.4 kV electrical network using a boost transformer as an additional means of voltage regulation is given. The system is based on voltage sensors installed in different parts of an eletcrical network sending information on voltage values to to the processing unit which generates a signal for voltage regulating supplied to the executive device and the working body whuch, in turn, change the on-load tap-changer position of a transformer. The paper justifies the need for the enhancement of the adaptive automatic voltage regulation system for different voltage classes wich allows controlling a voltage change at different power supply system levels and regulating voltage level in accordance with this change. For this problem the multi-level adaptive automatic voltage regulation systemis proposed. The system allows regulating the voltage not only in the 0.4 kV network but also in networks of higher voltage classes. The proposed system can be integrated into the structure of intelligent electrical networks.

Abstract:
The operating voltage in the substation must be maintained at its rated voltage within the specified standard because a voltage outside the specified range may cause a malfunction of the power facility and interfere with the stable power supply. Therefore, the voltage regulation process to maintain the rated voltage of the substation is essential for the stability of the power system. However, the voltage regulation process is currently performed manually by resident staff. Voltage regulation based on human judgment increases the uncertainty of voltage stabilization and makes efficient operation in consideration of the economic feasibility of power facilities difficult. Therefore, this paper proposes an automatic voltage stabilization system that can automatically perform voltage regulation. Instead of predicting the electrical load or overvoltage conditions studied so far, we focus on more direct, scalable input capacity prediction for an automatic voltage stabilization system. First, the proposed system predicts the input capacity required for a given situation through a trained stacked LSTM model. Second, an optimal regulation plan is derived through an optimization process that considers the economic feasibility of power facility operation. Additionally, the development of the user interface makes it possible to visualize the operation of algorithms and effectively communicate the models? predictions to the user. Experimental results based on real substation data show that the proposed system can effectively automate the voltage regulation process.

Abstract:
The growth of micro and mini distributed generation and, more recently, the use of electric energy storage systems and the incentives for electric mobility are important examples of the transformations that distribution networks have been going through. In this context, this paper firstly presents the impacts of uncoordinated plug-in electric vehicles (PEVs) charging in a real Brazilian distribution system. Four scenarios were elaborated with different PEVs penetration levels and the results show increased voltage unbalance, system losses, and violations of the steady-state voltage limits, even in the presence of an automatic voltage regulator installed in the medium voltage network. Then, as the main contribution, the potential usage of automatic voltage regulation at the low voltage network was investigated to minimize the negative impacts of uncontrolled PEV charging on distribution system steady-state operation. It is important to highlight that this is not a common practice of utilities in Brazil. The obtained results showed that regulating the voltage at the low voltage side could be an effective solution to keep the voltages within statutory limits.

Abstract:
The article addresses the problem of ensuring permissible voltage levels in distribution electrical networks of various types: distribution networks of large cities, regional distribution electrical networks, and distribution electrical networks containing renewable energy sources. The most typical factors causing the voltage to go beyond the permissible limits specified by the relevant regulatory documents are pointed out. The negative factors conducive to the voltage at the consumer end deviating from the permissible limits, including a long length of network lines, high network load, low controllability of the network, load schedule nonuniformity, and poor observability of the network, are analyzed. The existing principles of voltage control in electrical distribution networks, namely, automatic and seasonal regulation, are studied. A distribution electrical network test model representing a real network fragment is developed. The model operation modes have been verified based on the data of measurements carried out in the original distribution electrical network. The voltage distributions in a medium voltage network during its operation under the conditions of the highest and lowest loads are demonstrated. It is shown, on the test model example, how the network voltage can be controlled by automatically regulating the voltage at the power supply center and selecting a fixed position of the NLTC at 10/0.4 kV transformer substations. It is shown that the use of power transformer OLTCs does not ensure sufficient means for adequately controlling the voltage in networks containing long power lines and featuring highly nonuniform seasonal and daily load schedules. The technical efficiency and economic feasibility of using automatic voltage regulation devices on 10/0.4 kV transformers for local voltage control are analyzed. The economic efficiency of applying automatic voltage regulation devices at 6--10/0.4 kV substations was evaluated in comparison with other means for improving the power distribution network voltage quality by upgrading the 10 kV feeder lines or installing a voltage booster at the inlet to the problematic 10 kV network section. The application field of automatic voltage regulators in the form of semiconductor devices for regulating the transformer output voltage at distribution transformer substations is shown.

Abstract:
The combined application of Load Frequency Control (LFC) and Automatic Voltage Regulation (AVR), known as Automatic Generation Control (AGC), manages active and reactive power to ensure system stability. This study presents a novel hybrid controller with a (1+PDD2)-(1+TI) structure, optimized using the Mirage Search Optimization (MSO) algorithm. Designed for dual-area power systems, the controller enhances both LFC and AVR by coordinating voltage and frequency loops. MSO was chosen after outperforming five algorithms (ChOA, DOA, PSO, GTO, and GBO), achieving the lowest fitness value (ITSE = 0.028). The controller was tested under various challenging conditions: sudden load disturbances, stochastic variations, nonlinearities like Generation Rate Constraints (GRC) and Governor Dead Band (GDB), time-varying reference voltages, and ±20% to ±40% parameter deviations. Across all scenarios, the (1+PDD2)-(1+TI) controller consistently outperformed MSO-tuned TID, FOPID, FOPI-PIDD2, (1+PD)-PID, and conventional PID controllers. It demonstrated superior performance in regulating frequency, tie-line power, and voltage, achieving approximately a 50% improvement in dynamic response. MATLAB/SIMULINK results confirm its effectiveness in enhancing overall system stability.

Abstract:
The influence of wind farms, inclusion of distributed energy and the energy market has a large impact on the voltage profile in a transmission system. The Croatian Transmission System Operator HOPS has implemented VVC (Volt Var Control) system which was one of the subprojects included in the EU co-founded Sincro.Grid smart grid project that was financed by the EU CEF fund. The main goal of the project is to raise voltage quality in the transmission network. VVC system is an optimal power flow-based application which calculates the optimal solution regarding the desired objective function, available control variables and a defined set of constraints. To achieve the calculated optimal power system state, control of field devices is included in the process of optimization by shifting tap changer positions or changing setpoint values of reactive power injection. Voltage and reactive power constraints are set accordingly to available regulating devices included in the optimization.
 The lack of automatic coordination of reactive power resources motivated this work for implementing an advanced VVC for real time control of reactive power in partially automatic and fully automatic (closed loop) mode using the optimal power flow (OPF) algorithm. Due to its complexity, the closed loop approach of reactive power regulation is rarely used in the TSO community and the HOPS is one of the first TSOs that implemented regulation in such manner. Except fully automatic mode of operation, VVC can be used in semi-auto or manual mode. For a successful implementation several safety algorithms are implement to avoid many unwanted situations in the power system such as voltage breakdown, overloading of regulating equipment and similar

Abstract:
This paper proposes a new single-input dual-output [SIDO] soft-switched resonant full-bridge converter, which has asymmetrical structures for the isolated multiple outputs. The proposed structure is capable of supplying different loads having dissimilar voltage-current characteristics and independent of each other. This converter features wide range of zero current switching (ZCS) turn-off and automatic load-voltage regulation. In automatic load-voltage regulation, converter maintains constant voltage without the need of change in frequency or duty ratio during load change. First, the modes of converter operation are explained and then design of key parameters have been outlined. A laboratory prototype for 380[Formula: see text]V, 500[Formula: see text]W as main output and 24[Formula: see text]V, 50[Formula: see text]W as auxiliary output for an input voltage range of 40–50[Formula: see text]V was built-up and tested. Experimental results confirm the viability of voltage regulation, ZCS and power efficiency of the proposed converter.

Abstract:
Synchronous generators used for hydro power and nuclear power is a well known topology but there is a vast amount of intricate technologies and methods to making them function properly. This masters thesis covers the development, implementation and verification of a magnetisation system for a synchronous generator. The software implementation is made in the LabVIEW programming environment and uses a high performance CompactRIO with an FPGA for measurements, calculation and output control signals. Together with several peripheral devices, the CompactRIO forms an excitation system and most importantly, an automatic voltage regulator. This system keeps the output voltage of the generator stable and has a variety of safety features such as over excitation limits, under excitation limits and a V/Hz limiter. The resulting system successfully monitors and controls the generator characteristics and the controllers, based on PI controllers, have short rise times, low overshoot and no significant static error. This magnetisation system was verified on a 185 kW synchronous machine and all functions showed satisfying results with the exception of the implemented power system stabiliser which need to be re-tuned.

Abstract:
Automatic voltage regulation is necessary for all power producing synchronous generators to ensure that the produced power have a constant and stable voltage level and to sustain grid stability. The aim of this thesis is to design and build an automatic voltage regulator for a synchronous generator. A six-phase permanent magnet alternator will be used to excite the rotor with solid-state relay controlled rotating bridge rectifier. The field current is regulated by a closed loop control system that is based on a programmable logic controller, PLC. Programing of the PLC is executed in the developing environment CoDeSys, IEC 61131-3, which is the international standard for programing PLC applications. Simulations for predicting the system behavior is done with a web based in-browser tool, circuitlab.com. The results show a good performance of the regulator and the closed loop system although there is room for improvement of the solid-state controlled rectifier system.

This thesis has been performed in order to earn a master's degree in electrical engineering. The task was to implement an automatic voltage regulator, AVR, to control the terminal voltage of the synchronous generator Svante at the Division of Electricity at Uppsala University. The AVR uses Bluetooth technology to transfer a control signal produced by a programmable logical controller, PLC, to phase- mounted SSRs that decides what proportion of the AC from a six-phase brushless exciter that is to be used for the magnetization of the rotor. Test runs of the AVR were preformed with a regulator optimized according to the Ziegler-Nichols method and a static exciter that uses brushes and slip rings to apply voltage to the rotor winding. The results obtained complies with the assigned requirements set for this thesis and the AVR. The primary focus of this thesis mainly lies in the construction of the control system, which include the programming of both PLC and Bluetooth communicating devices.

Abstract:
There are many ways to produce energy, using e.g. gas or hydro turbines. To guarantee a stable power output, it is important to consider components that could control and adjust the output power automatically. The intention of this thesis work is to carry out a pre-study and system design of a mobileplatform simulator system that could be used by companies like Siemens and help them to reduce their OPEX (Operational expenditure) and easily evaluate their AVR (AutomaticVoltage Regulator) solutions and test improvements. In this document, Siemens has decided to call the simulator system, MPSS (Mobile Platform Simulator System). The pre-study includes the theory behind energy production, synchronous generator, simulator system, AVR, control systems and electrical grid. Furthermore, the pre-study includes selection of the proposed components for the simulator system and design of the complete simulator system that will be built by the Siemens R&amp;D engineers at a later stage. The Mobile Platform Simulator System (MPSS) is intended to test the AVR performance, which is a component with its prime purpose being to maintain the output voltage values from the generator at a fixed value, regardless of the current being drawn by the load. It is important that these output values are constantly regulated during the process of producing electricity, so that problems such as overvoltage, overcurrent etc. can be prevented. The MPSS will also be able to simulate real working scenarios e.g. from the different components of an energy production system, such as gas and hydro turbine, synchronous generator, AVR, electrical grid and serve for personnel training. The MPSS will consist of three main components; Simulator, AVR and control system. Therefore, the report will initially provide the background and general theory behind the synchronous generator, AVR and control system used in power generation systems. General information about the electrical grid is also provided. Furthermore, the report suggests the best possible choice for the necessary components to build a MPSS as well instructions on how to perform event simulation. The necessary documentation, including a circuit diagram to support the building of the MPSS by the R&amp;D engineers at late stage, is also provided. Finally, the general analysis of the technical and non-technical aspects related to the choice of components, work process, method and result are discussed in the end of this report.<br>Det finns många sätt att producera energi, genom användning av exempelvis gas- eller hydroturbiner. För att garantera en stabil produktion är det viktigt att noga överväga komponenter, som kan styra och justera uteffekten automatiskt. Avsikten med detta arbete är att göra en förstudie och systemdesign av ett simulatorsystem som kan användas av företag som Siemens, med avsikt att hjälpa dem att minska sin driftskostnad(OPEX), och lättare kunna utvärdera sina AVR-lösningar (Automatic Voltage Regulator)och möjliga testförbättringar. För detta arbete har Siemens bestämt att kalla systemet för ett mobilt simulatorsystem eller MPSS (Mobile Platform Simulator System). Förstudien innehåller teorin bakom energiproduktion, synkrongenerator generator, simulatorsystem, AVR, styrsystem och elnät. Ett urval av de olika komponenterna för simulatorsystemet och en slutgiltig design tas fram. Det kompletta simulatorsystemet kommer i ett senare skede att byggas av forsknings- och utvecklingsingenjörerna på Siemens. Simulatorsystemet är avsett att testa AVR-prestanda, vilket är en komponent vars huvudsakliga syfte är att upprätthålla utspänningsvärdena från en generator inom ett fast intervallvärde, oberoende av vilken effekt som en last drar. Det är viktigt att utgångsvärden ständigt regleras under elproduktionsprocesser så att utgångsvärden hålls inom systemets tillåtna gränser så att problem som över-/underspänning, över-/underström, över-/underfrekvens etc. kan förhindras. Simulatorsystemet kommer också att kunna simulera verkliga arbetsscenarier för olika komponenter i ett energiproduktionssystem, såsom gas- och hydroturbin, synkrongenerator, AVR och laster, exempelvis elnät, samt kunna användas vid personalutbildning. Simulatorsystemet kommer att bestå av tre huvudkomponenter; Simulator, AVR och styrsystem. Inledande beskrivning av arbetets bakgrund och allmän teoretisk kring komponenterna synkrongenerator, AVR och styrsystem, som används vid i kraftgenereringssystem, ges. Även en allmän bakgrund om elnätet och dess funktion presenteras. Därefter presenteras förslag på bästa möjliga val av nödvändiga komponenter för att bygga ett simulatorsystem. Ett förslag om hur händelse simulering görs samt vilken nödvändig dokumentation och kretsdiagram som behövs för att bygga ett simulatorsystem presenteras. I slutet av detta arbete presenteras en allmän analys av de tekniska och icke-tekniska aspekterna kring val av komponenter, arbetsprocess samt metod och resultat.

Abstract:
This thesis focuses on the design of an electrical drive system for the purpose of high precision motion control. A modern electrical drive is usually equipped with a current regulated voltage source along with powerful motion controller system utilizing one or more micro-controllers and/or digital signal processors (DSPs). That is, the motor drive control is mostly performed by a dedicated digital-motion controller system. Such a motor drive mostly interfaces with its host processor via various serial communication protocols such as Profibus, CAN+, RS-485 etc. for the purpose of receiving commands and sending out important status/control signals. Considering that the motor drives lie at the heart of every (multi-axis) motion control system, the aim of this thesis is to explore the design and implementation of a conventional DC motor drive system suitable for most industrial applications that require precision and accuracy. To achieve this goal, various underlying control concepts and important implementation details are rigorously investigated in this study. A low power DC motor drive system with a power module, a current regulator and a motion controller is built and tested. Several design revisions on these subsystems are made so as to improve the overall performance of the drive system itself. Consequently, important &ldquo<br>know-how&rdquo<br>required for building high performance (and high power) DC motor drives is gained in this research.

It is well known that a crucial factor determining the transmission capacity with regards to the voltage stability limit of a stressed power system, is the limitation of field and stator current of overexcited generators. These limiters are commonly referred to as overexcitation limiters (OEL) and stator current limiters (SCL). This thesis investigates the representation of overexcitation limiters and stator current limiters in the Swedish power system and how they could be implemented in the power system simulator PSS/E. Dynamic simulations in PSS/E are performed to investigate and validate differences between model types and parameters. The thesis compares different types of limiters and presents a representative set of parameters based on the documentation and implements them into PSS/E. The result from the study is a recommendation to migrate to limiter model MAXEX2 for generators without stator current limiters. The MAXEX2 model uses an inverse time characteristic which is becoming more common in installed voltage regulators. This feature makes it possible for extended use of generators before limiter action is applied. The MAXEX2 model is also possible to tune into a fixed time delay to represent older types of limiters.

Abstract:
nÃo hÃ<br>Este trabalho apresenta a aplicaÃÃo do algoritmo de OtimizaÃÃo por Enxame de PartÃculas (PSO â Particle Swarm Optimization) para sintonia Ãtima de controladores associados à regulaÃÃo de tensÃo e ao aumento do amortecimento de geradores sÃncronos utilizados em plantas termelÃtricas de ciclo combinado. Para representaÃÃo matemÃtica do gerador sÃncrono, utiliza-se o modelo linearizado de terceira ordem do sistema mÃquina conectada a uma barra infinita, vÃlido para estudos de estabilidade a pequenos sinais. Os parÃmetros do regulador automÃtico de tensÃo (AVR â Automatic Voltage Regulator) e do estabilizador de sistema de potÃncia (PSS â Power System Stabilizer) sÃo determinados de maneira Ãtima pela ferramenta computacional proposta. Os parÃmetros obtidos para o AVR e PSS sÃo comparados com valores calculados por tÃcnicas de sintonia convencionais, baseadas em aproximaÃÃes das equaÃÃes que descrevem o sistema. Os resultados de simulaÃÃes a variaÃÃes na tensÃo de referÃncia, considerando a anÃlise da resposta temporal do sistema controlado, demonstram que o PSO à uma tÃcnica eficiente na sintonia dos parÃmetros do AVR e PSS, destacando-se sua simplicidade, baixo esforÃo computacional e boa caracterÃsticas de convergÃncia.<br>This work presents the application of the Particle Swarm Optimization (PSO) algorithm for optimal tuning of controllers associated with voltage regulation and damping enhancement of synchronous generators used in combined cycle power station. For mathematic representation of the synchronous generator, the third order linearized model of a single machine connected to an infinite bus, valid for small signal stability studies, is used. The Automatic Voltage Regulator (AVR) and Power System Stabilizer (PSS) parameters are optimally determined by the proposed computational tool. The parameters obtained for AVR and PSS are compared with values calculated by conventional tuning techniques based on approximations of the equations that describe the system. The simulations results to reference voltage disturbances, considering the time response analysis of the controlled system, show that PSO is an efficient technique in the tuning of AVR and PSS parameters, with emphasis on its simplicity, low computational effort and good convergence characteristics.

Abstract:
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>Os sistemas de controle de excitação em máquinas síncronas devem detectar com bastante rapidez as mudanças causadas pela entrada de carga no gerador isolado e atuar no sistema de excitação de forma rápida e eficiente, para manter a tensão terminal em níveis desejados. Ao contrário de outros trabalhos realizados nesta área com circuitos eletrônicos analógicos, em muitos casos, este controlador pode ser construído utilizando tecnologia microcontrolada por possuir alto nível de eficiência no controle, circuito com flexibilidade para implementação de diferentes estratégias de controle e baixo custo para produção. A abordagem deste trabalho consiste em uma proposta para aplicação de um controle de excitação automático utilizando uma malha PID, com opções de controle manual, monitoramento de tensão terminal e temperatura de estator da máquina, utilizando um microcontrolador PIC16F877A da empresa Microchip Technology. Os resultados obtidos a partir de ensaios práticos em laboratório com partidas diretas de motores de indução (1 e 2 cv) com um gerador de 2 kVA mostra que a atuação do controlador recuperou a tensão terminal em pouco tempo, para o setpoint adotado. E por fim, os resultados obtidos foram comparados com os tempos de resposta de outro conhecido regulador automático de tensão encontrado no mercado, para comprovar o bom desempenho de controle deste projeto.<br>The excitation control systems in synchronous machines must very quickly detect changes caused by load increase on the isolated generator and act on the excitation system in a rapid and efficient way in order to maintain terminal voltage at optimal desired levels. Unlike other works related with this area which used analog-based electronic circuits, this controller can in many case be built utilizing microcontrolled technology which is more efficient and flexible to implement different control strategies, as well as having a low cost of production. The approach of this research consists in a proposal to apply an automatic excitation controller, utilizing a PID control loop, including manual adjustments and monitorings of terminal voltage and stator temperature of the machine. It employs a PIC16F877A microcontroller from the Microchip Technology Company. The results obtained through practical tests in laboratory with a direct online start of induction motors (1 and 2 HP) on a 2 kVA generator show that the controller acts to recover the terminal voltage to the adopted setpoint in a reduced time. Finally, the results were also compared to the time of response provided from another well-known automatic voltage regulator found in the market, in order to prove the good control performance of this project.<br>Dissertação (Mestrado)
