城市电网规划中负荷同时率的选择技术研究

Selection Technique Research on Load Simultaneity Factor in Urban Power Grid Planning

负荷同时率是电力系统规划中的一个重要参数。首先介绍了电力系统现状负荷同时率的影响因素以及现状负荷同时率计算分析方法,并且计算出了各级负荷同时率,由此分析了在缺少部分低压数据时综合负荷同时率的准确性;其次结合空间负荷预测以及负荷特性,提出了在城市电网规划中规划负荷同时率的计算分析方法。

Load simultaneity factor is an important parameter in power system planning.Firstly,the factors influencing the load simultaneity factor in power system are introduced as well as the calculation and analysis methods of load simultaneity factor,and then the load simultaneity factor at all levels are calculated,which analyzes the accuracy of comprehensive load simultaneity factor when lacking part of low voltage data.Secondly,combined with spatial load forecasting and load characteristics,the calculation and analysis methods of the load simultaneity factor are proposed in urban power grid planning.
