Abstract
A starting and stopping method for a static synchronous series compensator (SSSC) is provided. A starting process includes: connecting a converter to a shunt transformer, and closing a breaker which connect the AC system and the shunt transformer to charge the converter until the DC voltage is stable; opening the breaker, and connecting the converter to a series transformer through a change-over switch; and deblocking the converter, and controlling a current of a bypass switch of the series transformer to approach zero. A stopping process includes: switching a control mode of the converter to make the current of the bypass switch approaches zero when closed the bypass switch, then controlling a current of the series transformer to be gradually reduced to zero to make the series transformer out of service, and blocking the converter.
