Research on Analysis and Calculation of Reactive Power Optimization with Arbitrary Segmentation Area

文章在对分割点进行等效和遗传无功优化的基础上,提出了任意分割区域无功优化计算的思想和寻优算法,给出了任意分割区域及遗传算法无功优化的流程。以某省110 kV变电站为算例,采用任意分割区域无功优化算法进行了计算,并对计算结果与实测值进行了比较。结果表明,在基本不影响电压水平的前提下,采用任意分割区域无功优化算法对提高电容器投入率,优化经济调度,降低线路线损有较强的指导意义。同时,由于实现了无功优化计算范围的任意选择,方便了无功电压线损定量计算分析管理工作。

Based on the equivalent and genetic reactive power optknization for segmentation node, the idea and optknization algorithm of reactive power optknization calculation with arbitrary segmentation area was put forward. The flow. of reactive power optmization with arbitrary segmentation area and genetic algorithra was given. With the 110 kV substation in certain province as a caiculative example, the calculation adopting reactive power optknization algorithm with arbitrary segmentation area was carried out, and the calculating result was compared with the value of actual measurement. The results show that the reactive power optknizafion algorithm has more strong guidance memmg for rising the eapaecitanee ratio of putting into service, optknizmg economic dispiaehMg, and reducing line losses. At the same time, due to the realization of arbitrary selection of reactive power optimization calculation scope, it is easy for quantitative calculation and analysis of line losses management of reactive power.
