摘要
小水电的接入对配电网的电压分布有直接的影响,影响的大小和小水电的接入位置有很大的关系。本文采用美国伊利诺伊大学开发的电力系统仿真软件包Power World对福建某地区一个47节点,3电源网络进行仿真分析,仿真结果直观、形象的反映出电网电压的分布情况,研究了小水电在丰水期、枯水期接入电网位置对电网电压参数的影响,并给出了结论,小水电并网后适合接在电网中间偏末端。
The access of small hydropower has a direct effect on voltage distribution of distribution network and the size of such effect has much to do with the position of small hydropower. In this paper, a power system simulation package Power World which is developed by the University of Illinois in the United States is adopted to simulate and analyze a network with 47 nodes and 3 power sources in some region of Fujian Province. The result can reflect voltage distribution intuitively and visually. This paper has researched the effect of the position of small hydropower on voltage parameter of network in high-water period and low-water period and got the conclusion that small hydropower is suitable to be connected to the position close to the end of the grid.
