摘　　要：分析了冲击过压过流及突变对感应电机动态特性的影响,利用状态空间法建立了表征功率损耗的性能指标函数。提出将冲击作为约束条件,通过静态优化性能指标函数获得最优参数配置的思想。仿真曲线和实际波形表明,该方法抑制了冲击,降低了功率损耗。The effects of over voltage,over current and surage impacts on the dynamic performance of induction machine were studied.The performance index representing thyristor's power loss was established by means of state space modeling tool.Taking advantage of impacts' restriction conditions,the idea that obtaining optimal parameter configurations through optimizing performance index in steady state was proposed.The simulation curves and actual waveforms show that this method significantly restrains impacts and reduces power loss.
