The world's first HVDC circuit breaker successfully completed short circuit test

May 20, China can build planning and Design Group Zhejiang Institute to participate in the design of China's independent R & amp; D and manufacturing of the world's first 200,000 kv high-voltage DC circuit Breaker-Zhoushan Flexible System Zhouzhou Converter station DC Circuit breaker, the completion of the first short-circuit test, its performance in the actual system short-circuit conditions have been fully tested,
It has accumulated experience for DC circuit breaking related technology. On the basis of the traditional single-pole grounding short-circuit test, the double-pole short circuit test is carried out for the first time in this boat fixed converter station, and the UAV hanging line is used for the first time.
Zhejiang Academy undertakes the transformation of power distribution device and the design of test site of Converter station in this short-circuit test project. The test results show that the DC Circuit breaker is successfully moved under a variety of short-circuit conditions, which fully verifies the action performance of DC Circuit breaker in the process of short circuit fault of the system, and marks the maturation of HVDC breaking technology.
