摘要:
      线损率是体现电网运行水平、降损技术和管理水平的重要经济性指标。随着经济的发展,负荷用电结构也将发生变化,将对电网线损率产生影响。文中考虑了电力传输过程中的输入、输出以及售电环节的损耗,构建了分压线损率模型,定量分析了分压线损率与售电比例之间的关系,并求出了分压线损率最小时的售电比例。算例分析表明,所提的分压线损率模型及其计算方法可以得到售电比例变化时分压线损率的变化情况,有助于电网对未来线损率的把控,提升电网经济性。
Abstract:
      Line loss rate is an important economic index to reflect the operation level, loss reduction technology and management level of power grid. With the development of economy, the structure of load utilization will change, which will affect the line loss rate of power grid. Considering the input and output in the process of power transmission and the line loss in the process of electricity sales, this paper develops a line loss rate model at each voltage level. Then the influence of electricity sale proportion on the line loss rate at each voltage level is quantitatively analyzed based on this model. Then the electricity sale proportion is calculated when the line loss rate at each voltage level is minimum. The example shows that the variation of line loss rate at each voltage level can be obtained by the proposed model when the electricity sale proportion changes, which is helpful to control the future variation of line loss rate and enhance the economical efficiency of power grid.
