Reactive Power Compensator

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.

Raphson Method

One of the major causes of voltage instability in power system is the reactive power limit. Therefore, this paper aims to analyze the effect of Static Var Compensator (SVC) on voltage stability of a power system. There are many ways to control the voltage, but in this paper only focus on the SVC and IEEE-9 buses. The SVC circuit and IEEE-9 buses were designed and modelled in Power World. The Newton Raphson method was applied to compute the load flow solution. Then, the reactive power (Q) was injected to SVC and the effect of SVC on IEEE 9-buses were studied. The analysis of voltage control was considered the conditions of fault occurred at the bus. The simulation results obtained in Power World demonstrate that the improvement voltage in the IEEE 9-buses when the Q was injected into SVC circuit. Besides, the QV curve was plotted to show the sensitivity and variation bus voltages with respect to the Q injection.

Reactive Power Compensator

The objective of this paper is to present the challenges, methodological approach and possible solutions for the overvoltage issue during the winter light load period in the Main Interconnected Transmission System (MITS) of Oman after introducing the new 400kV system. Load flow studies of the planned MITS in 2016, including representation of other local and GCC interconnection grids, have shown overvoltage issues at the 400kV substations in Oman during winter off-peak demand. These voltage issues can even lead to difficulties in synchronizing the 400kV circuits. Simulation results are presented to define the size and location of a reactive power compensator which can resolve such overvoltage issues. Many options of the reactive power compensation, including fixed and variable means, have been studied and the best option (fixed shunt reactors) is selected.

Background & Objective: Harmonic amplification is one of the primary issues in power system networks. The objective of this study is to manage the harmonic event and its significant effects on power quality. A new control approach that uses Artificial Intelligence (AI) is proposed and applied to a Distribution Static Synchronous Compensator (DSTATCOM). DSTATCOM is a FACTS device that can achieve highly effective reactive power compensation to reduce and/or damp the harmonic amplification in power system networks. Results & Conclusion: Simulation results are obtained using the MATLAB/Simulink package. The validity and effectiveness of using the AI approach are proven based on the DSTATCOM FACTs device with linear and nonlinear loads. Analysis results are discussed.

Aiming at the situation of the low power factor of coal mine power system, this paper puts forward an integrated distribution scheme of reactive power compensation based on SVG. In this paper, not only the disadvantageous influences of reactive power of coal mine power network are analyzed, but also the working principle and advantages of SVG are introduced. This paper proposes a distribution scheme of three-level reactive power compensation, which is to compensate in the sides of high voltage, high-low voltage power distribution and the long-distance high-power loads. According to the results of theoretical calculation and MATLAB simulation, the scheme can reduce the power loss and increase the power factor, so the power quality of coal mine can be improved.

For resolving the problem that power filter cannot work normally because TCR (thyristor controlled reactor) generates extra third harmonic current under asymmetrical voltage, the paper proposes the estimation method of current capacity that TCR generates extra third harmonic current under asymmetrical voltage. Considering extra third harmonic current under asymmetrical voltage, Optimum method based on genetic algorithm is used to design the parameters of power filter. With reactive power compensation and harmonic suppression project of a steel mill as example, the proposed method is simulated by Matlab. Simulation results show optimized power filter can eliminate extra third harmonic current effects under asymmetrical voltage, meet the requirement of reactive power compensation, reduce harmonics current that load injects into system, and guarantee the power filter safe operation under asymmetrical voltage.
