Abstract:
ABSTRAKSuatu sistem PLTMH bertipe turbin screw telah direalisasikan di desa Ciherang, Banjaran Jawa Barat. Tetapi putaran turbin dan generator tidak dapat stabil, karena pembebanan pada generator selalu berubah-ubah. Oleh karena itu diperlukan sebuah sistem kontrol yang dapat menjaga putaran turbin pada kisaran 30 rpm dan putaran generator pada kisaran 1500 rpm. Pada paper ini dikaji pengembangan sistem kontrol turbin air tipe screw, menggunakan governor elektrik. Perangkat governor elektrik ini berbasis Arduino, yaitu Arduino Mega 2560 dan Arduino Uno yang dilengkapi sensor putaran, dan motor listrik sebagai aktuator yang menggerakkan sebuah pintu air untuk mengatur bukaan bucket. Arduino Mega 2560 berfungsi sebagai microcontroller sedangkan Arduino Uno berfungsi sebagai pengatur pembukaan pintu. Hasil pengujian system menunjukkan bahwa system dengan Arduino ini dapat mengatur putaran turbin dan generator sehingga mencapai 1500 rpm dengan toleransi 5%. Dengan demikian dapat disimpulkan bahwa governor elektrik berbasis Arduino dapat diterapkan pada pengaturan putaran turbin screw.Kata kunci: turbin screw, sistem kontrol,governor elektrik, arduino ABSTRACTA microhydro based on screw turbine type has been realized in Ciherang village, Banjaran, West Java. But operation of the turbine and generator are unstable, due to load fluctuation. The system need a control system that can keep the turbine rotation in the range of 30 rpm and the rotation of the generator in the range of 1500 rpm. In this paper study of the development of screw turbinecontrol system based on electric governor is presented. This electric governor is based on Arduino namely Arduino Mega 2560 dan Arduino Uno and equipped with a generator speed sensor send and electric motor as an actuator to adjust the opening of the bucket. The system test results show that the controller based on Arduino can adjust the turbine and generator rotation so that it reaches 1500 rpm with a tolerance of 5%. Thus it can be concluded that Arduino-based electrical governors can be applied to control screw turbine speed.Keywords: screw turbine, control system, digital governor, arduino

Abstract:
The paper considers a low head hydro units control problem by using the modern control theory for turbine governor design. The design of optimal and suboptimal turbine governor is performed by using the optimal control theory and projective controls method. Implementation of modern control theory in contemporary turbine governors is fairly easy to obtain due their realisation in digital technology. Comparison for the closed-loop system dynamic performances, shows that better results are obtained with optimal and suboptimal governors as compared to conventional turbine governors.

This paper studies the effect of the soft feedback in hydro-turbine and its governor system on power system transient stability. Low frequency oscillation phenomenon in which the hydraulic turbine sets participate occurred on power system many times this year, which with no mechanism discovered. In this paper, we first study the effect of mechanical load moment output of the prime mover system on the mechanism of low frequency oscillations, then by analysis of small-signal stability on hydro-turbine and its governor system and simulation experiments on an two-generator power system using PSASP, we come to the conclusion that: If the soft feedback output values of hydro-turbine governor systems are set small in the power system, it will come to the unstable oscillation condition.

Abstract:
This Master’s Thesis work deals with the development of improved hydro turbine models for the evaluation of a hydraulic power generating system performance in response to small disturbances in power system analysis tool. These improved models must be able to reflect the possible interaction between the hydraulic system and power system in the computer simulations of a power plant equipped with Francis turbines.The accuracy of a Hydraulic Power Generating System is studied by means of analysis of the dynamic behaviour of different models of the hydraulic machine and conduit system. The stability study of different models for Synchronous Machines and Turbine Governing System are beyond the scope of this work.Appropriate representations of the hydraulic turbine and conduit system are developed in various models of varying degrees of detail. Firstly, nonlinear models for a simple turbine without surge tank considering the inelastic and elastic travelling wave effects have been developed. After that, nonlinear models considering the inelastic and elastic travelling wave effects for a turbine with surge tank for Hydropower Systems with long length penstocks are implemented. Finally, the nonlinear models for a turbine with long length penstocks are linearized at an operating point considering both the nonlinear turbine characteristics and the travelling wave effects.The Master’s Thesis work is divided into three parts. The first part, comprising Chapters 2 to 8, reviews the physical characteristics and mathematical models of the components of a hydraulic power generating system. The influence of each component of the power system by means of appropriate mathematical models is essential for the understanding of system stability. The second part, comprising Chapters 9 to 11, deals with the dynamic study of the system stability characteristics of the different hydraulic power generating system models implemented in SIMPOW and LVTrans. Finally, the third part, Chapter 12 and Chapter 13, presents the discussion of the simulation results of the hydroelectric power system models, and draws general conclusions on this work and suggests possibilities for the approach further work, respectively.It was concluded that approaches based on nonlinear and linear models including the elasticity of the conduit system and the nonlinear turbine characteristics extracted from the Hill Charts, are the most accurate models for any acceptable study of the interaction between hydraulic system and power system.The study of dynamic performance and interaction between the hydraulic system and power system of these extended linear and nonlinear models including the elastic water hammer effect and varying the nonlinear characteristics of the hydraulic turbine must be studied in detail.

Abstract:
The thesis describes the development of a generic nonlinear computer model of a pumped storage hydroelectric scheme. The model combines the hydraulic, electrical and control systems. In particular, this model includes the water hammer effects, the hydraulic coupling in the common water supply tunnel, the power system stiffness and the electrical coupling between the generator and the power system. The benefit of the simulation is that it gives insight into the plant characteristics and improves understanding of the physical phenomena involved. A specific case of the model for Dinorwig power station is tested against the plant responses and establishes a good degree of confidence in the simulation. The model is used to evaluate governor performance and establish stability boundaries for various operating conditions. The model is also used to design a new black-start regime which allows Dinorwig to energise the power system after blackout, with individual units picking up incremental loads up to 15% of machine rating while ensuring that frequency deviations remains within limits. Another application of the model is to explain why a period of sustained power oscillation occurred at Dinorwig and to identify under what circumstances this can take place. Linearised system models are used for governor tuning and root locus and Bode plot methods applied to establish the optimum governor settings for different operation conditions. The results demonstrate the significance of hydraulic coupling and the power system (grid) size on governor tuning. The final part of the work addresses conversion of the model to run in real-time and interfacing it with an actual unit governor. The results demonstrate the practicality of the hardware-in-the-loop simulation as a technique for safely implementing and testing new controllers or enhancements to the current controller.

Abstract:
Hydropower is a flexible energy source that is essential for balancing the electrical power system on all timescales, from seconds to years. In addition to intra-hour regulation, it provides frequency containment reserves (FCR-N,FCR-D) and frequency restoration reserves (mFRR, aFRR) to the grid. The turbine governor is a device responsible for controlling the power output and delivering frequency control to the system. The aim of this Master’s Thesis project is to develop a new hydropower turbine governor in MATLAB/Simulink, which contains all critical functionality from the existing governor and with the same performance. The new governor should as far as possible comply to the well-established communication standard IEC 61850. A working model of the turbine governor has been built in Simulink that supports normal operation with frequency control, start and stop, load rejection, operation mode as synchronous condenser and more. Validations of the model against data from Akkats powerplant shows that the model behaves as a real governor during normal operation. Validations of the start sequence showed deviations during sequence 3 and 4 which can be explained by usage of different PID parameters. Using IEC 61850 as a nomenclature and as a way of structuring functions in the governor has also been possible. Implementing the whole standard for communication, requires that the control system also is renewed according to IEC 61850. Certain functions, as sequencing has thus not been done according to the standard. MATLAB and Simulink provide tools for building, simulating and testing implementations of the turbine governor. The contributions this platform can provide are; ease of implementation, optimization and testing of control strategies. Simulink also provides a graphical interface, which reduce system complexity. An optimal implementation requires a hardware with support for Simulink to get a transparent platform. Ultimately, these benefits could result in better frequency quality at a lower cost, which is essential for successful and cost-effective integration of other renewable energy sources such as wind- and solar power.

Abstract:
Frequency control systems are used to keep the grid frequency at the nominal value of 50.00 Hz. Vattenfall employ hydropower plants for this purpose as they can easily adapt their production to counteract frequency deviations. This master thesis focuses on trying to improve Vattenfall’s mechanism to provide FCR-N (Frequency Containment Reserve in Normal operation) for primary frequency control, i.e. the turbine governor. The efforts are made to operate the plants more efficiently, decreasing distribution losses and thus increasing the profits. The current control system was modelled in MATLAB’s simulation tool Simulink to understand its complexity and to be used as base for comparison. Then a new model was developed based on the idea to introduce a global governor for the frequency control in each plant which controls the input signal to the individual turbine governors of each unit. OPT-data (tabulated data indicating how to operate a plant at the highest possible efficiency) was used to determine how to optimally distribute the FCR-N among the active units in a plant in real-time. The conclusions which can be drawn from this master thesis are that it is possible to make a more optimal distribution of FCR-N in real-time. However, it has not been possible to make a good comparison between the two models and the results regarding the profits which can be made by introducing this new type of governor are therefore inconclusive. It is of crucial importance to make a better match of the regulating strengths of the two models in order to perform the comparison. Improving the parameter values for the proportional and integral gains of the individual controllers and the precision of the OPT-table lookups may further improve the new model and also make it possible to perform a valid comparison between the two models.

Abstract:
A wind turbine needs to be controlled to ensure its safe and optimal operation, especially during high wind speeds. The most common control objectives are to limit the power and rotational speed of the wind turbine by using pitch control. Aero Energy is a company based in Potchefstroom, South Africa, that has been developing and manufacturing wind turbine blades since 2000. Their most popular product is the AE1kW blades. The blades have a tendency to over-speed in high wind speeds and the cut-in wind speed must be improved. The objective of this study was to develop an active pitch control system for wind turbines. A prototype active pitch control system had to be developed for the AE1kW blades. The objectives of the control system are to protect the wind turbine from over-speeding and to improve start-up performance. An accurate model was firstly developed to predict a wind turbine’s performance with active pitch control. The active pitch control was implemented by means of a two-stage centrifugal governor. The governor uses negative or stalling pitch control. The first linear stage uses a soft spring to provide improved start-up performance. The second non-linear stage uses a hard spring to provide over-speed protection. The governor was manufactured and then tested with the AE1kW blades. The governor achieved both the control objectives of over-speed protection and improved start-up performance. The models were validated by the results. It was established that the two-stage centrifugal governor concept can be implemented on any wind turbine, provided the blades and tower are strong enough to handle the thrust forces associated with negative pitch control. It was recommended that an active pitch control system be developed that uses positive pitching for the over-speed protection, which will eliminate the large thrust forces. Keywords: pitch control, wind turbine, centrifugal governor, over-speed protection, cut-in wind speed, blade element-momentum theory, rotor, generator, stall, feathering.

Abstract:
This thesis proposes a method and develops a model for the participation of a combined cycle power plant to power system frequency control. Through the period of integration to the UCTE system, (Union for Coordination of Transmission of Electricity in Europe) frequency behavior of Turkey&rsquo
s grid and studies related to its improvement had been a great concern, so is the reason that main subject of my thesis became as &ldquo
Power System Frequency Control&rdquo
. Apart from system-wide global control action (secondary control)
load control loops at power plants, reserve power and its provision even at the minimum capacity generation stage, (primary control) are the fundamental concerns of this subject. The adjustment of proper amount of reserve at the power plants, and correct system response to any kind of disturbance, in the overall, are measured by the quality of the frequency behaviour of the system. A simulator that will simulate a dynamic gas turbine and its control system model, together with a combined cycle power plant load controller is the outcome of this thesis.

Abstract:
In this paper, the energy efficiency and dynamic performance of servopneumatic drivers are studied aiming at the correct sizing of the system components. The study is carried out through a non-linear dynamic model of a servopneumatic system. The simulation data are used along with the operating point method in order to understand the effect of loading conditions in the system performance, which is then used as a tool for component sizing. The results show the effects that the piston area has on the energy efficiency and dynamic behavior of the system. Moreover, the dependency of the servovalve size on the piston area is elucidated. A procedure to design an effective combination of piston area and sonic conductance of the servovalve is presented. A practical case where a servopneumatic system is being designed for the speed governor of a hydraulic turbine is described, evidencing the suitability of the proposed method for servopneumatic systems.

Esta dissertação trata do problema de agregação dinâmica de modelos de turbinas e reguladores de velocidade de unidades geradoras coerentes, visando o cálculo de equivalentes dinâmicos precisos para estudos de estabilidade transitória de sistemas de energia elétrica. Os modelos de turbina e regulador de velocidade considerados neste trabalho são do banco de dados de estabilidade do sistema elétrico brasileiro (modelos do Anatem). A metodologia empregada para o cálculo de equivalentes dinâmicos apresenta três etapas básicas: a identificação de geradores coerentes, a redução estática da rede e a agregação dinâmica dos modelos das unidades geradoras coerentes. A agregação dinâmica de um grupo de unidades geradoras coerentes consiste em representar esse grupo através de uma ou mais unidades geradoras equivalentes. As unidades geradoras coerentes podem ser representadas por diferentes modelos de máquina síncrona, sistema de excitação, estabilizador, turbina e regulador de velocidade. Os parâmetros lineares dos modelos equivalentes são ajustados numericamente através do método de Levenberg-Marquardt para resolver o problema de otimização multivariável. As respostas em freqüência são apresentadas em diagramas de Bode (módulo e fase). O bem conhecido sistema New England é considerado para a avaliação do desempenho dinâmico dos equivalentes. As curvas de oscilação angular e de potência elétrica dos geradores do sistema interno, assim como curvas de tensão em barras, obtidas com o sistema equivalente são comparadas com aquelas obtidas com a simulação do sistema completo.
This dissertation deals with the problem of dynamic aggregation of turbine and speed governor models of coherent generating units to calculate dynamic equivalents for power system transient stability studies. The turbine and speed governor models considered in this work are in the Brazilian electrical system stability database (Anatem models). The methodology used for the calculation of coherency-based dynamic equivalents has three basic steps: the identification of the coherent groups of generating units, the static reduction of the external network and the dynamic aggregation of coherent generating unit models. The dynamic aggregation of a group of coherent generating units consists of the representation of this group by one or more equivalent generating units. The coherent generating units can be represented by different models of synchronous machine, excitation system, stabilizer, turbine and speed governor. The linear parameters of the equivalent models are numerically adjusted using the Levenberg-Marquardt method in order to solve the multivariable optimization problem. The frequency responses are presented in Bode diagrams (magnitude and phase). The well known New England system is considered for the evaluation of the dynamic performance of the equivalents. The angular swing curves and electric power curves of the internal system generators as well as bus voltage curves obtained with the equivalent system are compared with those obtained with the simulation of the complete system.

The dynamic characteristics of the turbine system are nonlinear and difficult to predict.

The governor system parameters were simulated with the actual data available in the power plant. Traditional PID controller parameters are difficult to tune when used in control systems and a fuzzy PID which can tune the parameters on-line is introduced to be appropriate in the turbine governing control system.

This chapter highlights on the design, operation, and comparative analysis of different types of wind turbine systems with respect to steady state and transient phenomenal activities under rapid wind speed variations. Here, Type I, which is fixed speed induction generator based, and Type II, which is DFIG based, variable speed operated systems are initially compared. In the next part, Type III wind turbine system is presented, which uses DFIG; later, it is compared with the Type IV WT system, which uses permanent magnet synchronous generator. This chapter provides a comparative overview on existing wind power systems including an analytic discussion of key principles and innovations for wind turbines. In this energy conversion system, various designs of wind turbines, pitch angle controlled based variable speed wind turbines governed by help of electronic power converters, were preferred. This scope of dynamic simulation-based study is implemented using MATLAB Simulink to convey the feasibility of the proposed wind turbine models.

Abstract:
Each hydropower system incorporates with appropriate hydro turbine, and hydro governor unit. In the current work, an Automatic Generation Control (AGC) of two equal hydropower systems with Proportional-Integral-Derivative (PID) controller was investigated. The gain values of the PID controllers were tuned using Ant Colony Optimization (ACO) technique with one percent Step Load Perturbation (1% SLP) in area 1. The Integral Square Error (ISE), Integral Time Square Error (ITSE), Integral Absolute Error (IAE) and Integral Time Absolute Error (ITAE) were chosen as the objective function in order to optimize the controller's gain values. The experimental results reported that the IAE based PID controller improved the system performance compared to other objective functions during sudden load disturbance.

Abstract:
In this work, Artificial Intelligence (AI) based Ant Colony Optimization (ACO) algorithm is proposed for Load Frequency Control (LFC) of interconnected multi–area hydrothermal power systems. Area 1&2 are thermal power systems and area 3 is a hydro power system, all the areas are interconnected through the appropriate tie-line. Thermal and hydro power plants are applied with reheat turbine and electric governor respectively. Investigated power system initially applied with conventional Proportional-Integral (PI) controller and controller parameters are optimized by using trial and error method considering Integral Time Absolute Error (ITAE) objective function. After that, the system is equipped with Proportional – Integral – Derivative (PID) controller and controller parameters are optimized by using ACO algorithm with ITAE objective function. The superiority of the proposed algorithm has been demonstrated by comparing conventional controller. Finally, The Simulation results of multi-area power system prove the effectiveness of the proposed optimization technique in LFC scheme and show its superiority over conventional PI controller.

Abstract:
The dynamic characteristics of the steam turbine speed governor system is one of the major factor that influence the security of the power system. It has important practical significance for the security of the power system to establish the detailed dynamic model of the steam turbine speed governor system through parameter identification. This paper starts from the actual needs of the modeling of steam turbine speed governor system, several key issues such as field test of the speed control system, data preprocessing, parameter identification and simulation verification are researched, the solution of the key problems in the field static test and dynamic disturbance test is summarized, a variety of data preprocessing algorithms and parameter identification algorithms are achieved, and a new method for the simulation verification is proposed. On this basis, software based on MATLAB for the parameter identification of the steam turbine governor system is developed, which can perform the data preprocessing, parameter identification and simulation verification. The software offers a variety of parameter identification method to identify the linear and nonlinear part of the system model quickly and efficiently, and provides detailed qualitative and quantitative method for the evaluation of the simulation verification. The parameter identification results of steam turbine governor system of a power plant show that the software is user friendly and feature rich, and also show that it can complete parameter identification of steam turbine speed governor system intelligently and precisely.
