摘要 分析了含有电力电子元器件的电磁暂态仿真中的数值振荡现象和多重开关动作问题,提出一种基于后退欧拉法并考虑多重开关动作的变步长电磁暂态仿真算法。该算法利用线性插值技术处理开关动作,利用变步长后退欧拉法进行试探积分,能够有效处理多重开关动作并有效抑制数值振荡,且对仿真步长具有较好的适应性。通过典型电力电子整流电路和简化高压直流输电系统,对算法进行了适用性和效率分析,并与商业软件PSCAD的仿真结果进行对比,算例结果表明了该算法的正确性和有效性。

Abstract:Numerical oscillation problem and multiple switching events in power system electromagnetic transient simulation with power electronic devices are discussed in this paper. And then a variable step integration method considering multiple switching events is proposed, based on backward Euler method. In this method, linear interpolation is to change the switch state, and the variable step backward Euler method is used to the numerical integration. There are several advantages of the proposed algorithm, including effective treatment to multiple switches, significant inhibition to numerical oscillation, and favorable adaptability to step size. The effectiveness and efficiency of the algorithm are studied on typical power electronic rectifier circuit and simplified high voltage direct current transmission system, and the validity is also proved compared with the simulations by PSCAD.
