摘要
在分析开关磁阻起动/发电系统(SRS/G)运行机理的基础上,提出了一种基于Ansoft/Sim-plorer的SRS/G系统建模方法.该方法利用Simplorer的电路元件库搭建SRS/G的功率变换器及其外围电路,根据SRM小信号分析模型进行比例积分(PI)参数整定和参数优化,电机起动时采用转速外环PI调节加内环电流斩波、发电时采用电压外环PI调节加内环变开通角的控制策略对SRS/G系统进行了仿真分析.仿真结果与样机试验结果的比较验证了模型的正确性.该模型修改容易、直观性强,便于对不同的控制策略进行特性分析,为研究和设计SRS/G控制系统提供了一种有效的工具.
According to the principle of switched reluctance starter/generator（SRS/G）, a method for modeling SRS/G system is proposed, where the power inverter of SRS/G and its circuit are constructed with circuit components, and PI parameters are adjusted and optimized following the SRM small signal model. The variation parameters speed PI control and the current chop control are used when SRM operates in the starting state, whereas the variation parameters voltage PI control and angel position control are used in case of generator. Simulation and experimental resuits are compared to demonstrate the validity of the modeling method, which enables clearly to modify and analyze the different control strategies to offer one kind of effective tool for SRS/G control system.
