摘　　要：结合我国配电网网损大、电压合格率低的特点,提出了配电网无功优化规划的数学模型,分析了其在4种配电网无功补偿方式的应用。利用该数学模型可得到并联电容器的补偿容量和有载变压器分接头的位置,解决了补偿容量依据供电部门要求达到的功率因数确定,而不是依据用户用电时的实际效益、最佳电能质量、最小支付电费的经济功率因数来确定的问题。In consideration of the great distribution network losses and low voltage up-to-standard rate in China, a mathematical model for reactive optimization planning of distribution network is proposed, and its applications to four reactive compensation means for distribution network are analyzed. The compensating capacity of shunt capacitor and the location of on-load transformer tap changer can be obtained by use of the model, which solves the problem of determining the compensating capacity by the power factor specified by power supply department and not by the economic power factor of demand-side actual benefits, optimum power supply quality and minimuxa electric costs.
