摘要
介绍直流断路器的设计原理,利用PSCAD仿真软件建立了基于改进M ayr模式的电弧模型以及直流断路器的模型。比较了直流断路器两种不同的设计方法,并基于大量仿真试验,提出了直流断路器设计中元件参数的选择方案。最后通过PSCAD/EMTDC仿真,证明了该方案在HVDC工程MRTB设计中的可行性。
The design scheme for the DC circuit breaker was presented, and PSCAD was used to construct the are model and the DC breaker model based on the improved Mayr equation. Two different current interruption theories were compared, and a suitable parameter choosing scheme for DC breakers was proposed based on large amount of simulation data. PSCAD/EMTDC simulations proved the scheme feasible in MRTB design for HVDC projects.
