Analysis of Control and Performance Response of System using Scaled Model for STATCOM

축소모델을 이용한 STATCOM의 제어효과 및 계통응답 분석

This paper describes the theory and experimental result of scaled model of STATCOM. The STATCOM, a solid-state voltage source inverter coupled with a transformer, is tied to a transmission line. A STATCOM inject an almost sinusoidal current of variables magnitude, at the pont of connection. This injected current is almost in quadrature with the line voltage, thereby emulating an inductive or capacitive reactance at the point of connection with the transmission line.
