摘要：
Hybrid cascade multi-terminal HVDC technology is one of the important development directions of UHVDC transmission in the future, and its reclosure strategy is an important factor related to reliable operation of HVDC system. Firstly, the fault characteristics of hybrid cascade multi-terminal HVDC transmission lines are analyzed, and then the application of combined HVDC circuit breaker in hybrid cascade multi-terminal HVDC transmission is studied. On this basis, an adaptive reclosure method of DC circuit breaker based on the voltages at both ends of DC circuit breaker is proposed. A typical hybrid cascade multi-terminal DC transmission model with composite DC circuit breakers is built on PSCAD/EMTDC, and the reclosure strategy is verified. © 2019, Power System Technology Press.
