Introduction

HVDC in China's power grid construction, power transmission for long distance and large-area networking has a very broad prospects for development, as is currently the In order to solve the high-voltage, large-capacity, long-distance power transmission and important means of asynchronous networking. According to China's direct DC transmission engineering requirements and high pressure Project stream transmission technology trends undertaken in the digestion and absorption of imported technology, the domestic HVDC project construction experience and independent research equipment Based on the research to develop national standards for HVDC transmission system equipment. Including basic standards, equipment standards and master control and protection equipment standard. Projects have been completed or are ongoing to develop a total of 19 national standards. (1) "performance of the first part of the steady-state performance HVDC system" (2) "Performance of HVDC systems failures second part of the operation."
