Research on the SVC Auto-Compensating Method Based on the Variable Reactor

Abstract

The objective of this work is to research on a SVC auto-compensation method to improve the power factor of the power supply system. Firstly, the principles of the reactive power compensation of FC+TCR are analyzed qualitatively. According to the deficiencies of this compensator, a novel SVC auto-compensating method based on the variable reactor is presented. The reactor controlled by anti-parallel thyristors is namely as the variable reactor in this method. The secondary-side equivalent inductance of the variable reactor is varied by adjusting the SCR firing angles. And then, the equivalent inductance of the variable reactor of the compensator branch is adjusted indirectly for compensating the corresponding reactive power after the working conditions of the load are changed. Therefore, the auto-compensating of this var compensator is realized. The auto-compensating principles of this compensator have been analyzed, and a research on the compensating parameters of this compensator is given emphatically in this paper. Finally, the essential operation steps of this SVC compensation method are given. The research of this paper has laid a theoretical foundation for this compensator in industrial applications.

Software Design for Dynamic Reactive Compensation System

“…It leads to the reduction of the power factor. With the huge change of the industrial environment, the traditional reactive power compensator is difficult to meet the needs of the reactive power compensation [1]- [3].…”

A Dynamic Reactive Power Compensation Method of Super High-Power and High-Voltage Motor

“…As a consequence of this, problems like voltage instability and fluctuations become very common due to the mismatch between the demand and supply of reactive power. Though, authors have advocated the use of capacitor banks to improve voltage stability and to compensate the reactive power in the process of SHHM soft-starting [4]- [8], the fixed capacitors fail to deliver the required amount of reactive power to the SHHM in order to stabilize the system voltage.…”
