摘　　要：对并网光伏发电系统的自动监测和控制进行了设计和研究。并网光伏发电系统中太阳电池阵列产生的直流电通过光伏并网逆变器转换为与大电网相同相位与频率的220 V或380 V正弦交流电,然后并入大电网。分布式光伏发电系统组成的微网和大电网双向交换,通过大电网调节并网光伏发电系统不足和多余的电力,使系统可靠地输出稳定、波形良好的正弦交流电。The automatic monitoring and control of the grid-connected photovoltaic power generation system were designed and studied. The direct current was generated by the solar array of photovoltaic power generation system and converted into 220 V or 380 V sinusoidal AC the same phase and frequency with large power grid through the PV grid-connected inverter and then connected into the power grid. The micro-grid composed of photovoltaic power generation system and large power grid could exchange in bidirectional way, the lack and excess power of grid-connected photovoltaic power generation system was adjusted through the large grid, making the system reliably output stable sinusoidal AC with good waveform.
