摘要：

The paper investigates the Static Synchronous Compensator (STATCOM) stability enhancement. Two major factors of the STATCOM instability, power system strength and Phase-Locked Loop (PLL) delay, are analyzed theocratically as well as by exact digital simulation. A 24-pulse GTO converter model is designed to represent the exact operation of the STATCOM and the digital simulations are performed in a power transmission system. An Automatic Gain Controller (AGC) is designed to ensure the stable operation of the STATCOM under various load conditions. The operation of the additional supplementary controller is also validated by digital simulation, using the 24-pulse converter model, to demonstrate the effect of the AGC on stabilization of the STATCOM.
