摘要
本文通过分析GIS设备扩建时对接和耐压试验的特点,结合西北某330kV变电站工程实际,对330kV、110kV接线进行优化研究,旨在避免因GIS设备扩建造成全站停电,且减少扩建时部分母线的停电时间及其对周边110kV负荷供电造成的影响,提高系统的供电可靠性,力求优化后的方案不仅在技术上、而且在经济性上也更优。
This article analyzed the characteristics of GIS equipment＇s docking and pressure tests during its expansion , combined with the live example of a 330kV substation project at the northwest , carried out the optimization study of 330kV, 110kV single line diagram.The study aims to avoid the station blackout caused by the expansion of GIS equipment , significantly reduce the outage time of bus and the im-pact to 110kV-load power supply at the periphery , improve the reliability of system＇s power supply, and try to achieve a plan with techni-cal and economical optimization .
