摘要
昆明电网中的110kV变电站的高压侧母线的主接线方式为单母分段接线,主要有2种运行方式:并列运行和分段运行。对2006年昆明电网丰大运行方式下的2种母线运行方式下的电网的电压合格率,网损率和N-1开断校验等3个方面进行了计算,并根据计算结果比较分析了2种运行方式。较之并列运行,110kV汤池变母线分段运行方式下,电压越限的母线数目增多;电网网损率略低;分段运行方式下汤池1号主变压器开断,电压越限的母线数目增多。
Single bus segmentation operation is applied in 110 kV buses of Kunming power grid, which mainly includes subsection and parallel operation modes. From the three aspects of voltage qualification rate, losses and N-1 outage checkout, calculation and comparison analysis of the two operation modes were performed in Kunming power grid in 2006. The conclusion is that numbers of over or under voltages buses is increased, losses is slightly decreased when 110 kV bus of Tangchi transformer is under segmentation operation mode.
