Abstract:

TCR-TSC static reactive power compensator (SVC) is the most widely used in the field of power system reactive power compensation. This type of reactive power compensator can not only compensate the reactive power required in the power system, but also handle the over-compensation problem well. This paper will establish a MATLAB simulation model to simulate the TCR-TSC SVC, focusing on the dynamic reactive power compensation characteristics of the TCR-TSC SVC in suppressing voltage fluctuations. The simulation results show that the TCR-TSC SVC has a better dynamic reactive power compensation effect.

Abstract:

Traditional static var compensators (SVCs) employ shunt reactors and capacitors. These standard reactive power shunt elements are controlled to produce rapid and variable reactive power. Power electronic devices like the thyristor etc. are used to switch them in or out of the network to which they are connected in response to system conditions. There are two basic types, namely the thyristor-controlled reactor (TCR), and the thyristor-switched capacitor (TSC). In this paper we wish to investigate a compensator where the reactor or capacitor is replaced by a series connected resistor and reactor (R-L). The performance equations are derived and applied to produce the compensator characteristics for each of the configurations. Their performances are compared, and the contrasts between them displayed. All three configurations are made to achieve unity power factor in a system.

Abstract:

Abstract Voltage sag is one of the power quality disturbances most frequently by customers because it can cause economic loss for the customers especially industries and commercial customers. The main source of voltage sags are faults in transmission and distribution beside two others namely motor large starting and transformer energizing, both the voltage sags have less effect on the equipment. Voltage sags can cause degradation performance of the equipment, and it depends on the magnitude and the duration. The voltage sags that occur in the power system can be compensated with installed Static VAR compensator (SVC) and Static synchronous compensator (STATCOM) in the distribution system bus. The purpose of the study is to compare both types of the device used to mitigate voltage sags in simulation using Alternative transient program (ATP) software. The voltage sag results from the short circuit faults. The method proposes the installation of the two compensator devices alternatively at one of the IEEE thirteen busses systems. The result shows the STATCOM is better than the SVC to handle mitigation of voltage sags compared with the SVC.

Abstract:

Application of Flexible AC Transmission Systems (FACTS) devices in a power system is a promising and more efficient way for the transfer and control of bulk amount of power. One of the problems encountered in power-systems operation is the generation of unbalanced voltages and currents in the presence of long transmission lines with few or no transpositions. This includes possible unbalances arising in source and load conditions, or indeed any items of plant such as shunt and series reactors. To improve or investigate these unbalance effects in any detail, a 3-phase load-flow solution that allows representation of all possible unbalances as they exist in the power-systems network without making any assumptions is essential. This paper deals with the three phase power flow incorporating Static Var Compensator (SVC). Here SVC is modeled using variable reactance modeling technique and incorporated into the single phase and three phase load flow. Newton Raphson power flow algorithm is adopted here. The performance of SVC to control the power flow and regulating voltage in the network is discussed. The performance analysis is carried out for 4 case studies namely single phase power flow, single phase power flow with SVC, three phase power flow and three phase power flow with SVC. The change in power flow and losses due to the unbalanced load condition in the three phases in illustrated. The studies are carried out in a standard 5 bus test system. Keywords: Three Phase Power flow, Static Var Compensator, Unbalanced system, Negative sequence components, Zero sequence components.

Variability in power systems is increasing due to pushing the system to limits for economic purposes, the inclusion of new energy sources like wind turbines and photovoltaic, and the introduction of new types of loads such as electric vehicle chargers. In this new environment, system monitoring and control must keep pace to insure system stability and reliability on a wide area scale. Phasor measurement unit technology implementation is growing and can be used to provide input signals to new types of control. Fuzzy logic based power system stabilizer (PSS) controllers have also been shown effective in various studies. This thesis considers several choices of input signals, composed assuming phasor measurement availability, for fuzzy logic-based controllers. The purpose of the controller is to damp power systems’ low frequency oscillations. Nonlinear transient simulation results for a 4-machine two-area system and 50 machine system are used to compare the effects of input choice and controller type on damping of system oscillations. Reactive power in the system affects voltage, which in turn affects system damping and dynamic stability. System stability and damping can be enhanced by deploying SVC controllers properly. Different types of power system variables play critical role to damp power swings using SVC controller. A fuzzy logic based static var compensator (SVC) was used near a generator to damp these electromechanical oscillations using different PMU-acquired inputs. The goal was again improve dynamic stability and damping performance of the system at local and global level. Nonlinear simulations were run to compare the damping performance of different inputs on the 50 machine system.

Abstract:

Bakgrunden till detta projekt är att Vattenfall Eldistribution AB (nedan kallat Vattenfall) kommer att införa ett avgiftssystem för inmatning av reaktiv effekt till sitt elnät. Avgiften införs till följd av problem på elnätet som orsakas av reaktiv effekt. Umeå Energi Elnät AB (nedan kallat Umeå Energi) har historiskt matat in reaktiv effekt vilket motiverade detta arbete som utreder den reaktiva effekten på Umeå Energis elnät samt bidrar med information om två alternativa tillvägagångssätt att bemöta avgiften. Alternativ 0 är att kompensationsutrustning inte installeras, utan att ett abonnemang på inmatning av reaktiv effekt upprättas. Alternativ 1 är att kompensationsutrustning installeras. För att utreda den reaktiva effekten erhölls och behandlades data på reaktiv effekt i Umeå Energis nät. Historisk kondensatordrift togs fram för år 2016 ur händelsehistoriken hos Umeå Energis driftcentral. Kondensatordriften år 2015 kunde enbart erhållas från ett tidigare arbete på Umeå Energi eftersom ett begränsat antal händelser lagras i händelsehistoriken. Genom att subtrahera kondensatorernas produktion från den reaktiva effekten i Umeå Energis anslutningspunkter som uppmätts av Vattenfall erhölls data som mer representerade underliggande fenomen på nätet. Utan kondensatordrift beräknades inmatningen enligt Vattenfalls definition uppgå till cirka 34 MVAr utifrån data från 2015 och 2016. För åren 2018 till och med 2023 beräknades ändringar i reaktiv effekt till följd av förändringar på Umeå Energis nät. Vid beräkningarna försummades ledningarnas induktiva karaktär, vilket gav ett tomgångsscenario med maximal produktion av reaktiv effekt. År 2023 beräknades inmatningen ska ha ökat till 59 MVAr till följd av förändringar på Umeå Energis nät. Med antagandet att Umeå Energi inte kommer att drifta kondensatorbatterierna så att inmatningen höjs föreslogs för alternativ 0 val av abonnemang på inmatning av reaktiv effekt för åren 2018 till och med 2023 utifrån de 34 MVAr som nämnts ovan och inverkan från förändringarna på nätet. År 2019 föreslogs ett abonnemang på 41 MVAr, och 2023 föreslogs ett på 59 MVAr. Kostnaderna för dessa beräknades enligt Vattenfalls tariff till 820 000 kr respektive 1 187 000 kr. Kostnaden för eventuell överinmatning av reaktiv effekt beräknades med tariffen för överinmatning årligen uppgå till maximalt 76 000 kr med 95 % sannolikhet enligt den korrigerade standardavvikelsen hos inmatningen utan kondensatordrift åren 2015 och 2016. Optimal kondensatordrift beräknades för åren 2015 och 2016 genom att addera den produktion av reaktiv effekt från befintliga kondensatorbatterier som gav minst absolutvärde i reaktiv effekt. Beroende på hur ofta kondensatordriften justerades erhölls olika resultat. En undersökning av störningar till följd av kondensatorkopplingar rekommenderas för att få en förståelse för förutsättningarna för optimal kondensatordrift. Det bedömdes inte ekonomiskt motiverbart med mer avancerad kompensationsteknik såsom statiska VAr-kompensatorer då variabla reaktorer kan kompensera dygns- och säsongsvariationer i reaktiv effekt. Den reaktiva effektproduktionen i ledningar är störst på 145 kV-nivån och kommer öka i framtiden på denna nivå. Det är därför sannolikt här kompensationsutrustning såsom reaktorer först bör installeras. För att kunna ta så bra beslut som möjligt angående den reaktiva effekten rekommenderas att snarast möjligt ingå ett arbetssätt som om avgiftssystemet redan tagits i bruk och utöka ett representativt dataunderlag.
The background of this project is that Vattenfall Eldistribution AB (hereinafter referred to as Vattenfall) will establish a system of fees for input of reactive power. This will be done due to problems in the grid caused by reactive power. Umeå Energi Elnät AB (hereinafter referred to as Umeå Energi) has historically input reactive power, motivating this work which investigates the reactive power in the grid of Umeå Energi and provides information on two alternative approaches to responding to the fee. Alternative 0 entails no installation of compensation technology, and that a subscription for reactive power input is established instead. Alternative 1 entails that compensation technology is installed. To investigate the reactive power, data on reactive power in the grid of Umeå Energi were obtained and processed. Historical operations of capacitor banks for the year 2016 were obtained from the history of events of the control center at Umeå Energi. The operations of the capacitor banks during 2015 could only be obtained from an earlier work at Umeå Energi since the number of events stored in the history is limited. By subtracting the capacitor banks’ production from the reactive power measured by Vattenfall in the connections of Umeå Energi, data more representative of underlying phenomena were obtained. Without capacitor production of reactive power, the input was calculated according to the definition of Vattenfall to about 34 MVAr, by using data from 2015 and 2016. For the years 2018 through 2023, changes in reactive power due to changes in the grid of Umeå Energi were calculated. These calculations did not consider inductances, and thus yielded zero-load scenarios with maximum reactive power production. By the year of 2023, the input was calculated to have increased to 59 MVAr due to changes in the grid of Umeå Energi. Assuming that Umeå Energi will not operate the capacitors so that the input is increased, for alternative 0 subscriptions for input of reactive power were suggested for the years 2018 through 2023 by considering the abovementioned 34 MVAr and the changes in the grid. Subscriptions of 41 MVAr and 59 MVAr were suggested for the years 2019 and 2023 respectively. The costs of these were calculated with the fee specified by Vattenfall to SEK 820,000 and SEK 1,187,000 respectively. Calculations with the applicable fee yielded that the yearly cost of possible over-input could amount to a maximum of SEK 76,000 with a 95 % probability, using the corrected standard deviation of the input without capacitor production of reactive power for the years 2015 and 2016. Optimal capacitor bank operations were calculated for the years 2015 and 2016 by adding the production of reactive power from existing capacitor banks which yielded the minimum absolute reactive power. Depending on how often the capacitors were operated different results were obtained. An investigation of power quality disturbances due to capacitor bank operations is recommended to achieve an understanding of the conditions for optimal capacitor bank operations. It was not deemed economically justifiable to install more advanced compensation technologies such as static VAr compensators since variable reactors are able to compensate daily and seasonal variations in reactive power. The production of reactive power in cables is the largest on the 145 kV level and will increase in the future on this level. It is therefore likely here compensation technologies such as reactors should be installed first. To be able to make as good decisions as possible concerning the reactive power, it is recommended to as soon as possible commence a working method as if the fee system had already come into effect; thus increasing the amount of representative data.

Abstract:

Modern interconnected power systems are becoming highly complex and sophisticated, while increasing energy penetrations through congested inter-tie lines causing the operating point approaching stability margins. This as a result, exposes the overall system to potential low frequency power oscillation phenomena following disturbances. This in turn can lead to cascading events and blackouts. Recent approaches to counteract this phenomenon are based on utilization of wide area monitoring systems (WAMS) and power electronics based devices, such as flexible AC transmission systems (FACTS) and HVDC links for advanced power oscillation damping provision. The rise of hybrid AC-DC power systems is therefore sought as a viable solution in overcoming this challenge and securing wide-area stability. If multiple FACTS devices and HVDC links are integrated in a scheme with no supervising control actions considered amongst them, the overall system response might not be optimal. Each device might attempt to individually damp power oscillations ignoring the control status of the rest. This introduces an increasing chance of destabilizing interactions taking place between them, leading to under-utilized performance, increased costs and system wide-area stability deterioration. This research investigates the development of a novel supervisory control scheme that optimally coordinates a parallel operation of multiple FACTS devices and an HVDC link distributed across a power system. The control system is based on Linear Quadratic Gaussian (LQG) modern optimal control theory. The proposed new control scheme provides coordinating control signals to WAMS based FACTS devices and HVDC link, to optimally and coherently counteract inter-area modes of low frequency power oscillations inherent in the system. The thesis makes a thorough review of the existing and well-established improved stability practises a power system benefits from through the implementation of a single FACTS device or HVDC link, and compares the case –and hence raises the issue–when all active components are integrated simultaneously and uncoordinatedly. System identification approaches are also in the core of this research, serving as means of reaching a linear state space model representative of the non-linear power system, which is a pre-requisite for LQG control design methodology.

Abstract:

A new static VAr compensator (SVC) topology suitable for high voltage ac systems is proposed. This high pulse naturally commutated SVC is based on the ability of the ac/dc naturally commutated converter to regulate the absorption of reactive power and a novel method of achieving high pulse operation (i.e. with the dc ripple reinjection scheme). Steady state and dynamic operating performance of the scheme are tested in a variety of ac system conditions with the help of two models techniques, a scaled down equivalent in hardware and a high voltage representation in a computer simulation package (EMTDC-PSCAD). There is a linear relationship between firing angle and reactive current, and the 36-pulse harmonic characteristic of the compensator current is consistantly maintained over this operating range and in a variety of ac system conditions. Its dynamic performance is compared to that of the thyristor controlled reactor (TCR), when operating in the same power system environment, showing that the proposed scheme's voltage control ability is consistently faster than the TCR. The main difference in the compensator performances, however, is the proposed scheme's inherent temporary overload capability. This difference shows that there is the opportunity for the proposed scheme to supersede the TCR technology and further work to clarify the compensator's viability is considered to be worth while.

Abstract:

The research work conducted and presented forward in this document is the evaluation of real time values obtained using three recording devices at two independent locations and implementing them as recorder devices in Eskom’s power system. The research work conducted was presented at an IEEE International Conference (ICIT2013) and Appendix A shows the accepted paper presented. A derived model within a simulation software package known as DIgSILENT PowerFactory is created and Electromagnetic Transient (EMT) studies are performed and then compared to the real time values obtained using the OMICRON CMC 356’s. Transformers are normally energised via a circuit breaker which is controlled by an auxiliary closing contact. By applying system voltage at a random instant in time on the transformer windings may result in a large transient magnetizing inrush current which causes high orders of 2nd harmonic currents to flow under no load conditions. A philosophy known to mitigate these currents is to energise the transformer by controlling each individual phase 120 degrees apart with the first pole closing at the peak on the voltage waveform. Transients produced due to 500MVA transformers been introduced into the power system at a certain space in time can cause nuisance tripping’s at the particular location where the respective transformer is energised. OMICRON EnerLyzer is the software tool used for the Comtrade recordings at both locations. Four independent case studies are generated within EnerLyzer software and the relevant Comtrade files are extracted for the four independent case studies relative to Transformer1 and Transformer2 switching’s. TOP software, which is a mathematical tool used to analyse Comtrade files, is then used to analyse and investigate the four case studies. Results from DIgSILENT PowerFactory are then generated according to the derived model. The results extracted depict three scenarios, indicating a power system that is weak, strong and specifically a power system that correlates to the actual tripping of a Static VAr Compensator (SVC). The results are all formulated and then evaluated in order to produce a conclusion and bring forward recommendations to Eskom in order to effectively ensure the Dedisa/Grassridge power system is reliable once again.

Abstract:

Large horsepower motors on weak power systems cause problems associated with excessive voltage drops. The voltage drops may be steady state caused by heavy system loading or they may be transient caused by starting a large motor. One way to solve the problems is to use a Static Var Compensator (SVC) on the power system, to compensate for the reactive loads and stabilize the voltage on the utility and in the station. SVCs have been used for years by electric utilities and are now being used for some industrial applications. This paper gives an overview of the technology and describes a pipeline application.
