摘　　要：结合湖北省2019年-2020年代表日负荷实测和理论线损计算结果,简要介绍了两年代表日电网运行情况,接着分析了两年代表日理论线损计算结果的分电压、分元件的构成情况,全面论述了两年代表日各电压等级理论线损的变化趋势和主要影响因素。最后根据各电压等级的实际情况,提出湖北电网降损措施和建议。Combined with the measured representative day load and theoretical line loss calculation results in Hubei Province from 2019 to 2020,this paper briefly introduces the representative day operation of power grid in two years,and then analyzes the composition of sub-voltage and sub-component of the two-year theoretical network loss calculation results,comprehensively discussing the variation trend and main influencing factors of theoretical line losses of each voltage level in two-year representative days.Finally,combined with the actual conditions of each voltage level,the paper puts forward loss-reduction measures and suggestions for Hubei power gird.
