| 摘 要： | 结合配电网的特征,建立了配电网无功优化的数学模型,采用N点分散补偿法对配电网无功补偿的最佳位置进行了研究,采用遗传算法对配电网无功补偿最佳容量和有载调压变压器分接头最佳档位进行了研究,编制了基于N点分散补偿法和遗传算法的配电网无功优化软件.以新疆某配电网为算例的计算结果表明:N点分散补偿法可确定补偿位置;遗传算法可确定变压器分接头档位,且在补偿容量和减少线损方面优越于N点分散补偿法.

| Abstract: | Based on the characteristics of power distribution network,mathematical models for reactive power optimization of distribution system are established.And by dispersed compensation at N nodes,how to determine the optical opposition of compensation is studied.Genetic algorithm is used to research the compensating capacity and the tap position of on-load tap changer.Based on dispersed compensation at N nodes and genetic algorithm,reactive power optimization programs of power distribution network are programmed..Calculation examples of CHANGJI power distribution network show that the genetic algorithm can be used to determine the tap position,and is more suitable to the compensation capacity and the energy loss than dispersed compensation method at N nodes. |
