Abstract

For power system stabilization, an advanced static VAr compensator (SVC) using the world largest GTOs, that is a self-commutated SVC, has been developed. The series connection technique of many high power GTOs for realization of a high voltage power converter was established. The effectiveness of voltage stabilization in power systems was verified through field tests and these large capacity self-commutated converters offer prospects of application to power systems. This paper introduces essential techniques for development, present the state of field tests, and proposes a new overcurrent protection method for high voltage power converters composed of many series-connected devices.<>
