Analysis on the influence of lossless electricity proportion variation to line loss rate

为了消除无损电量对线损率真实情况的掩盖,剔除无损电量对线损率波动的影响,对无损电量进行了定义,提出了一种无损电量占比对线损率影响的计算方法,用实例计算分析了黑龙江省各个电压等级以及各个地区无损电量占比对线损率的影响。分析结果表明:利用提出的方法计算分析黑龙江电网各电压等级与地区的线损率,能够准确计算出受无损电量占比影响后的电网线损率变化值。

In order to uncover the real situation of lossless electricity’s influence on line loss rate and eliminate the influence of lossless electricity on the line loss rate fluctuation,the definition of lossless electricity is given and a calculation method of the influence of lossless electricity proportion on line loss rate is proposed.The influence of different voltage levels and the lossless electricity proportions in each area of Heilongjiang Province on the line loss rate is analyzed by calculating with examples.The analysis results show that the way to use the proposed method to calculate and analyze the line loss rate of each voltage level and area in Heilongjiang Power Grid enables the power grid line loss rate variation after influenced by lossless electricity proportion to be accurately calculated.
