Modern Approaches to Controlled Static VAR Compensators design

The analysis of different approaches to the controlled thyristor static VAR compensators (CSVC) design is presented. The CSVC structural schemes are presented. The CSVC are carry out control of reactive power by controlling the effective value of the current flowing through the reactive element, changes in the resistance of the reactive element and changes in the effective voltage applied to the reactive element. The main features of the circuit design and control each of CSVC implementation are considered. The CSVC examples that implement each of the considered approaches are presented.
