城市电网运行水平分析及其改善措施

Operation Level Analysis and Inprovement Schemes of Urban Power Networks

笔者通过对某大城市电网的夏季高峰代表日的负荷实测的分析，提出了当前在电网运行中电压、无功功率、变压器及大用户等方面存在的各种问题，并针对这些问题提出了相应的改善措施．

Based on analysing the load data of a big city power network on representative summer days, this paper presents sorts of operation problem in power networks including voltage, reactive power, transformer and large users etc., and puts forward the improvement schemes for these problems.
