摘要/Abstract

摘要： 光伏电站并入电网的容量不断提高，其接入农配电网带来的影响已不容忽视。为有效评估其影响，结合张家口北部地区农配电网特点，对IEEE14节点模型做出相应改进。以PSAT为仿真平台，建立相应改进系统和光伏电站模型，分析了光伏电站并入农配电网后对地区电网电压稳定和线损造成的影响。进行了2类典型负荷变化的时域仿真。仿真结果表明，并入农配电网的光伏电站，对提高局部农配电网的电压静暂态稳定性、减小线损等方面有一定促进作用。

关键词: 光伏电站, 农配电网, 电压稳定, 线损, 负荷变化

Abstract: The capacity of photovoltaic power station connected to the grid is increasing, and its impact the rural distribution network can't be ignored. In order to evaluate its influence, firstly, the IEEE14 node model is improved considering the characteristics of a rural distribution network in Zhangjiakou area. Secondly the improved power system model and the photovoltaic power station model are established in the power system analysis toolbox (PSAT). The impacts of grid-connected photovoltaic power on the voltage stability and line loss of rural distribution network are investigated. In addition, time domain simulations with two kinds of typical load changes are carried out. The simulations show that the photovoltaic power station has a positive role on promoting static and transient voltage stability and reducing line loss of local rural distribution network.

Key words: photovoltaic power station, rural distribution network, voltage stability, line loss, load change
