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. HVDC transmission project is based on our actual needs and high pressure DC transmission technology development trends carried out. Projects in the introduction of technology digestion and absorption of domestic HVDC project construction experience and autonomous equipment Developed based on research to develop national standards for HVDC transmission system equipment. Including basic standards, master control and protection equipment standards Equipment standards. Projects have been completed or are ongoing to develop a total of 19 national standards.
