低压配电网无功优化研究

Research of Reactive Power Optimization in Low-Voltage Distribution Network

配电网作为电力网的末端直接与用户连接,网上设备多,系统存在着阻抗,电能在转换、输送、分配过程中伴随着大量损耗。基于配电网线损计算是指在给定的时段内,计算一个配电网系统中的所有元件产生的电能损耗这个概念,分析了配电网结构的特殊性和复杂性,适用于电力网的线损计算方法都不再适用,新提出的一些计算方法在计算机的实现上存在很大的缺陷,另外配电网中元件数太多,各个元件上的运行数据具有一定的随机性,收集较为齐全的运行计算参数非常困难,可以看出配电网线损计算具有十分重要的经济意义。

As the end of the power network,the distribution network is directly connected with the users.There aremany equipments on the network and there is impedance in the system.The power consumption is accompanied by agreat loss in the process of conversion,transportation and distribution.The distribution network loss calculation is tocalculate electric energy loss of all components of a distribution network system in a given period,and analyze theparticularity and complexity of distribution network structure.But the calculation methods are no longer applicable forline loss of power network.Some new proposed calculation method has great significance.
