A Study of Control System for Self-Commutated Converter Compensator

Abstract

A new control system for a self-commutated coverter compensator was studied which applied real and imaginary component of instantaneous power as control signals. The adequacy of the system was verified by digital simulation of EMTP under various conditions of system disturbances. Sampling periods of input signals for digitalizing the control system were also investigated both by digital simulations and Bode diagram. Both results were well agreed with each other, and a prospect of digitalizing the system was obtained.
