摘　　要：参考青海省海西、海南地区新能源送出及甘肃-青海断面功率极限,对该地区35 kV及以上电压等级电网在串补工程投运前后及新能源不同发电出力等典型方式下并网对线损的影响进行分析计算,总结出新能源发电对线损影响的变化规律,为电网分析决策提供技术依据。Based on the new energy output of Haixi and Hainan in Qinghai province as well as the Gansu-Qinghai section power limit,the impact of new energy grid connection of the 35kV and over-35kV power grids on the line loss is analyzed and calculated before and after the operation of the series compensation project with different power generation outputs of new energy.Then,the law of change of the impact is summarized,which provides technical basis for power grid analysis and decision-making.
