本例程是仿真风电机组并网农网末端，改善供电质量包含单相逆变器、锁相环、单项逆变滤波、电网的仿真。经过测量，风电机组补偿后的农网末端电压提高到9.908kV，电压偏移率下降到了0.92 。-The simulation is to simulate the end of the grid-connected rural power grid, to improve power quality, including single-phase inverter, phase-locked loop, single inverter filter, power grid simulation. After the measurement, the voltage of the rural network after the wind turbine compensation is increased to 9.908kV, and the voltage offset rate is reduced to 0.92 .
