摘要：

A de component contained in a output of a voltage source self-commutated converter makes a converter transformer to be de-magnetized, in the worst case causing an overcurrent due to saturation. We experienced the dc-magnetization of the converter transformer of a 50 MVA self-commutated SVC installed in the Shinshinano Substation of Tokyo Electric Power Company when system disturbances occurred by energizing of an adjacent large capacity transformer. After analyzing the problem, a novel de magnetization preventing control was developed that makes a fast flux correction according to the voltage de component detected in the converter output. This method was applied to the 50 MVA self-commutated SVC and produced satisfactory operation results.
