Single Phase Photovoltaic Grid-connected Inverse Power System Based on DSP

摘要：

As the energy crisis and the pollution are serious,the exploitation of solar has received more and more attentions.The configuration and principle of photovoltaic grid-connected power system are analyzed in detail.The method of maximum power point tracking is designed and the control principle of voltage and current double closed-loop is analyzed in this paper.At the same time an improved phase locked tracking method combined with software and hardware is presented.The experimental results show that the current waveform of grid-connected inverter has the same frequency and phase angle with the grid voltage,the power factor of grid-connected inverter is 0.999,which meets the design requirement entirely.
