Compensators in Power Electronics
The growing capabilities of power electronic components have developed the use of FACTS devices. The higher power levels have been made available in converters for highest voltages. The overall starting points are network elements influencing the impedance or the reactive power of a part of the power system. For FACTS devices, it has two terms to be explained. One of the terms is dynamic, which is used to express the fast controllability of FACTS devices which is provided by the power electronics. This is one of the main differentiating factors from the conventional devices. Another one is static, which is used to perform the dynamic controllability because it has no moving parts like mechanical switches. This article discusses about compensators used in power electronics, that includes Static Synchronous Series compensator (SSSC), TSSC, TSSR, TCSC and TCSR.
