基于PSCAD的高压断路器仿真模型
|
摘要
断路器是电力系统中最重要的控制和保护设备,但现有的断路器模型大多只能简单表现断路器的分合状态改变,故建立基于动态电弧的断路器模型。首先分析所选电弧模型,得到所需参数,再在PSCAD/EMTDC仿真软件中搭建断路器仿真模型,在MATLAB中针对电弧模型进行算法编程,并利用PSCAD中特殊接口调用MATLAB程序得到断路器开断故障全过程。通过仿真研究与比较,断路器切断故障时的电压电流与理论分析基本一致,验证了断路器模型的正确性,表明设计模型具有一定的参考性。
The circuit breaker was the most important control and protection device in the power system. However,the switching state was only simply represented by most of the existing circuit breaker models,so a circuit breaker based on dynamic arc was established. Firstly,the selected arc model was analyzed to obtain the required parameters. Then,the circuit breaker simulation model was built in PSCAD/EMTDC. The algorithm was programmed for the arc model in MATLAB,and MATLAB was called by special interface in PSCAD. Through the simulation research and comparison,the voltage and current of the breaker when the fault was cut off was basically consistent with the theoretical analysis. The correctness of the circuit breaker model was verified,which showed that the design model had a certain reference.
