摘要
分布式光伏电站可以通过控制并网逆变器的无功调节能力为电网提供电压支撑并作出一定量的无功补偿,当光伏有功出力为额定值时,逆变器是可实现以0.9以上的功率因数并网的,从而更好地提高光伏电站的无功控制能力。
distributed photovoltaic power plant can control the grid through the reactive capacity of the inverter to provide voltage support for the grid and make a certain amount of reactive power compensation, when the photovoltaic power output for the rated value, the inverter can be achieved to 0.9 or more Power factor grid, so as to better improve the reactive power control capacity ofphotovoltaic power plants.
