摘要
结合皖电东送工程,对特高压系统调试项目试验过程中的过电压及其对500 kV设备的影响等技术问题进行探讨.分析了当投切1 000kV空载线路,投切1 000kV空载变压器,投切特高压主变110 kV侧低压电容器组、电抗器组过程中,以及特高压线路人工短路试验中,引起的500 kV系统的过电压.并将仿真结果和规程进行了比较,提出了建议.
Abstract
This paper researches the Anhui-Shanghai transmission line project and analyze the overvoltage and impacts of UHV AC system commission on 500kV power system.Firstly,compute the overvoltage in the 500kV power system,when no-load 1000kV transmission line is switched.Secondly,calculate the overvoltage in the 500kV power system,when no-load 1000kV transformers is switched.Thirdly,analyze the overvoltage situation in the 500kV power system,when the capacitor and the reactors on the 110kV side of the UHV primary transformer are switched.Finally,simulate the overvoltage in the 500kV system during the artificial short circuit test in the UHV system.
