太阳能光伏发电系统并网逆变器的研究

Research on grid-connected inverter of photovoltaic generation systems

分析了太阳能光伏并网逆变器的控制方式中的重复控制。针对其输出滞后一个周期的缺点提出重复控制和极点配置结合的方法,利用Matlab/Simulink环境进行仿真。仿真结果证明加入极点配置后改善了系统的动态性能,且输出波形的波形畸变率减少。

A strategy named repetitive control was presented for grid-connected inverter of photovoltaic generation systems. According to its output lags behind a cycle faults, the method based on the repetitive control and poles placement was presented, and the simulation in Matlab/Simulink was given. The simulation results show that after joining poles placement, the method can improve the dynamic function of systems, and the THD of the output waveform is reduced.
