Link control panel of IGBT valve of chain static synchronous compensator

The invention relates to a link control panel of an IGBT valve of a chain static synchronous compensator. An energy storage circuit input and an energy storage circuit output of a high-potential dual power supply are connected with a primary equipment high potential side and a power supply changeover circuit input respectively, a power supply changeover circuit output is connected with a power supply monitoring circuit and a voltage signal input of a DC voltage detection circuit, an output thereof is connected with a logic protection circuit which is connected with an IGBT valve detection signal, a valve body temperature detection signal, a DC voltage detection signal and a fault indication signal, a valve body locking instruction and a valve status signal thereof are connected with a pulse distribution and dead zone processing circuit and a communication processor respectively, the communication processor is connected with a DC voltage signal at a DC, a light emission and receiving circuit, and a control instruction of the communication processor is connected with the pulse distribution and dead zone processing circuit. The link control panel is used for solving of complicated energy storage technology, imperfect trigger and real-time detection of the IGBT valve, anti-interference of the link control panel and communication with surface equipment in the prior art.
