摘要
根据油田配电网的特点，提出了一种计算配电网无功功率补偿的数学模型。分析了配电网的潮流，综合考虑了节约电能和设备投资两个经济指标，以配电网年运行费用最小为优化目标，运用该模型确定了合理而经济的补偿容量和最佳补偿位置。用这种算法可以实现配电网就地基本无功平衡，最大限度地减少配电线路上的电能损耗。实例说明，运用该优化补偿方案进行降损具有较好的经济效益。
This paper presents a new algorithm in regard to reactive power optimization for distribution system based on the features of oilfield distribution system. A mathematical model for the distribution system is developed and used to calculate power flow. Based on the power flow, the rational capacity and distribution of reactive power is determined. The balance of reactive power is realized in the place of user. An example proves that the new algorithm is benefit to reduce the energy losses of distribution line and raise the economical efficiency on optimal reactive power.
