分布式光伏并网对线路电压的影响研究

Study on the Influence of Distributed Photovoltaic Grid Connection on Line Voltage

基于分布式光伏的发展现状,用数学模型分析了分布式光伏并网对电力系统电压的影响,得出节点电压水平和线路压降与光伏容量和线路负载数值有关。通过Simulink仿真,确定不同光伏容量、负载容量等参数对线路电压的分布变化曲线,验证了理论正确性。

Based on the development status of distributed photovoltaic,the influence of distributed photovoltaic grid connection on power system voltage was analyzed by mathematical model,and it was concluded that the node voltage level and line voltage drop were related to the photovoltaic capacity and line load values.Through Simulink simulation,the distribution curves of different PV capacity,load capacity and other parameters on the line voltage are determined,which verify the theoretical correctness.
