摘要
10kV低压配电网引入光伏电源后,引起配电线路中传输的有功和无功功率的数量和方向的改变。研究了辐射状配电网络在不同位置并入不同容量的光伏电源后各负荷节点的电压幅值和总网损的变化,对33节点配电网进行了算例仿真,继而对电压分布的特点,光伏电源接入位置及最大接入容量限制进行了理论探讨。
The quantity and direction of active and reactive power in transmission of distribution circuit have changed after introducing 10kV low-voltage distribution grid into photovoltaic power supply.This paper researches the changes of voltage amplitude and total power loss in each load node after the radial distribution grid in different locations incorporated into photovoltaic power supply of different capacities.The author conducted an example simulation on 33 node distribution grid,and then conducted the theoretical analyses on characteristics of voltage distribution,interconnected location of PV power and the biggest interconnected level limit.
