摘要: 针对配电台区三相不平衡度较高及传统人工换相效率较低的问题,提出基于改进背包算法的人工换相台区三相负荷不平衡治理方法。综合考虑三相不平衡度和换相次数,构建多目标换相优化模型。将换相问题抽象转化为多背包模型,引入分层分区并行搜索(layered partitioned parallel search,LPPS)思想对算法进行改进。采用某居民配电台区实际数据开展算例分析,运用改进背包算法计算获得配电台区换相方案,结果表明换相前后三相不平衡度得到了明显改善。相较于传统背包算法,在保证治理效果的同时降低了换相次数,有利于提高配电台区经济运行效率。

Abstract: In view of the high degree of three-phase unbalance in the distribution station area and the low efficiency of the traditional manual phase change, a manual phase change optimization method based on the improved knapsack algorithm is proposed. The multi-objective phase change optimization model is constructed by considering the degree of three-phase unbalance and the number of phase changes. The phase change problem is abstractly transformed into a multi-pack model, and the algorithm is improved by introducing the idea of layered partitioned parallel search (LPPS). The actual data of a residential distribution area are used to analyze the case, and the improved knapsack algorithm is used to calculate the phase change scheme of the distribution area. Compared with the traditional knapsack algorithm, the number of phase changes is reduced while ensuring the treatment effect, which is conducive to improving the economic operation efficiency of the distribution area.
