摘　　要：提出只需在开关磁阻发电机每相定子绕组并联一个交流电容,形成交流开关磁阻发电机(AC SRG),周期性变化的相电感和电容构成LC参量振荡电路,输出交流电压,不需要功率变换器和位置传感器,磁链能用于两个象限;提出其电路模型和数学模型,分析稳定运行条件和机电能量转换过程,给出变速运行的电容值选定方法;建立仿真模型,仿真结果表明该系统能稳定运行,静动态性能较好,验证了AC SRG的可行性和简单性,适合用于偏僻地区的小型风力发电。Switched reluctance generators （SRG） is usually used as DC power by power converter providing excitation. The rotor position angle is identified by position sensor, as trigger signals of each phase master switch of power converter. But the simplicity and reliability of generating system are decreased. AC switched reluctance generator （AC SRG） that the output is AC voltage is proposed which each phase winding is paralleled with an external AC capacitor, the phase cyclical changes inductance together with capacitor forms a LC parametric oscillator circuit. It has no power converter and position sensors, and flux can be used in two quadrants. The circuit model and its mathematical model of it were presented. The conditions of stabile operating, electrical-mechanical energy conversion process were analyzed. The value of the selected variable capacitor was given. The simulation model of AC SRG was provided. The results shown that AC SRG generating system can run stable, static and dynamic performance is better. The feasibility and simplicity of it are verified. It suits for small size wind power generating system in remote areas.
