摘要
运用EMTDC/PSCAD仿真软件,建立能够反映断路器短路短延时和短路瞬时保护特性及电弧外特性的仿真模型。通过典型故障算例仿真表明,仿真模块能够准确模拟断路器的保护特性,为断路器保护特性的设计和保护参数的整定提供了仿真试验、研究的基础。
The simulation model was established based on EMTDC/PSCAD software, which can reflect the short circuit short delay and short circuit instantaneous protection characteristics and arc external characteristics. A typical fault example was given, and the simulation results show that the model can canlate the protection characteristics of circuit breaker aecurary, it provides foudation for design of protection characteristics and parameter setting for circuit breaker.
