根据开关磁阻风力发电系统工作原理及对并网过程分析, 结合Z源逆变器的单级 式升降压特性, 针对发电机输出直流电压偏低的情况, 采用基于SVPWM调制的Z源逆变器实现系统 并网的策略, 实现逆变后输出电压满足并网的要求. 通过并网逆变控制器的设计实现Z源网络的电容端电压的稳定及系统的有功功率和无功功率控制. 在Matlab/Simulink仿真平台下, 建立开关磁阻风力发电系统和Z源逆变器的仿真模型, 仿真运行结果表明Z源逆变器应用于开关磁阻风力发电并网系统中的可行性和有效性.

This paper proposes the use of Z source inverter with grid connected switched reluctance wind power generation systems. Based on the operation of switched reluctance generator (SRG) and requirements of grid-connected, considering the unique single stage buck boost feature of Z source inverter, Z source inverter with space vector pulse with modulation (SVPWM) is adopted to satisfy the voltage level when the SRG's DC output voltage is low. To maintain Z source capacitor voltage stable and control the active and reactive power by the regulation of boost factor and d-q axis current, the grid connected control method is designed for the system. Simulation system of wind power generation on SRG and Z source inverter are constructed based on Matlab/Simulink platform. The simulation results reveal that Z source inverter is feasible and valuable in wind power generation on SRG system.
