一个光伏并网单位功率因数并网模型，含有光伏阵列，且是三相逆变并网-A photovoltaic grid-unity power factor and network model, containing the PV array, and is a three-phase inverter grid

逆变器采用PQ控制，实现并网时的功率控制，可单位功率因数运行-use PQ control

官方例子，电压外环，电流内环，有参考意义，适合初学者。(Official examples, voltage outer ring, current inner ring, have reference significance, suitable for beginners.)

使用扰动观察法实现最大功率跟踪，使用电容电压外环，电感电流内环实现单位功率因数的并网逆变器双环控制。(The method of disturbance observation is used to realize the maximum power tracking, the outer loop of capacitor voltage and the inner loop of inductor current are used
