基于PSCAD的直流断路器电弧模型研究

In thisThis article describes the working principle of DC circuit breakers and breaking methods. Using PSCAD simulation software to build a model based on Mayr improved arc model and the DC circuit breaker,form which the crucial parameters can be got,such as the current conversion ability of DC circuit breaker, withstand voltage ability and energy absorption ability. The paper provided the basis for R&D of DC circuit breaker of HVDC project. Finally, PSCAD / EMTDC simulation model to prove the feasibility of the arc.
