摘要
为了提高交/直流电网的混合仿真速度,有必要使用分网并行的手段改进仿真方法。提出了一种交/直流混合电网机电暂态稳定仿真系统,交/直流子网模块用于将大交/直流电网划分为小交/直流子网,使每个子网可以并行仿真。同时对数值计算方法进行了改进,提高了仿真计算的效率和精度。以准新英格兰IEEE10机39总线为例,在电磁暂态仿真软件PSCAD(Power Systems Computer Aided Design Software)环境下验证了该方法的有效性。
In order to improve the hybrid simulation speed of AC/DC power grid,it is necessary to improve the simulation method of sub grid parallel.An electromechanical transient stability simulation system is presented for AC/DC hybrid power grid.The AC/DC sub network module is used to divide the large AC/DC power grid into small AC/DC sub networks,so that each sub network can be simulated in parallel.The numerical calculation method is improved for the efficiency and accuracy of simulation calculation.Taking IEEE 10-39 bus as an example,the effectiveness of the method is verified in PSCAD(Power Systems Computer Aided Design Software)environment.
