摘要:
针对一般PI控制存在测量干扰的问题,设计了带有前馈补偿器和电流反馈PI补偿器控制的微型光伏离网逆变器. 利用状态空间平均法建立理想反激转换器的小信号数学模型,给出了输入与输出之间的传递函数;设计了带有前馈补偿器和PI控制器的微型光伏离网逆变器控制算法. 为了验证提出的算法,通过微控制器实时对光伏电池板电压、交流输出电流、交流输出电压进行采样和计算,生成SPWM波形并驱动开关管来实现DC-DC升压变换和DC-AC变换,得到较为稳定的正弦输出. 对实验得出的结果进行分析,充分验证了控制算法的有效性和可行性.
Abstract:
Aimed at the measuring interference in proportional integral (PI) control, the micro off-grid photovoltaic inverter with feed-forward and current feedback PI compensator was designed. The small signal model of ideal flyback converter was constructed by the state-space averaging method to derive the transfer function from the input and output signal. Then the control algorithm of the micro off-grid photovoltaic inverter with feed-forward compensator and PI controller was designed. To verify the proposed algorithm, the real-time photovoltaic (PV) panel voltage, alternating current (AC) output voltage and AC output current were sampled and calculated by the microcontroller to generate the sinusoidal pulse width modulation (SPWM) waveform, which could drive the switch to realize direct current (DC)-DC boost converter and DC-AC converter. Finally, the stable sinusoidal output was obtained. The effectiveness and feasibility of control algorithm was verified by the experiments.
