Abstract: DC based Deicing is the only way to melt ice for power grid 500 kV and above. In order to solve the cooling problem of deicing device SVC, according to the research of mainstream cooling methods and system running environment, fullclosed deion watercooling system was designed. Based on PLC, touch screen and ModBus communication, the watercooling system could be controlled locally and remotely. Antiinterference technology was also applied to the system to overcome the harsh electromagnetic environment. The running result indicates that the system is stable and reliable, ensuring the Deicing device running under the normal status.
Key words: static var compensator（SVC）; watercooling; antiinterference
