摘　　要：由于电容器长期运行在户外环境,其实际投切动作可靠性受环境温度、湿度影响较大,存在实际补偿效果与预测补偿效果不一致问题,且分布式电源的海量并网也对台区电压的平稳运行带来较大的挑战。针对上述问题,本文考虑到配电台区数量规模庞大、资料收集不便等现状,提出一种数据驱动的台区无功资源充裕度评价方法,其基于台区基态模型及灵敏度分析拟合,利用台区低压侧电压运行数据,在线绘制无功需求曲线并从多个维度对台区无功资源的充裕度进行评价,实现台区无功资源的差异化分析和实用化在线评价。后以某台区为例进行了无功资源充裕度的评价分析,在不依赖复杂建模的情况下验证了本文所提方法的有效性。Due to the long-term operation of capacitors in outdoor environments,the reliability of their actual switching action is greatly affected by environmental temperature and humidity.There is a problem of inconsistency between the actual compensation effect and the predicted compensation effect,and the massive grid connection of distributed power sources also poses significant challenges to the smooth operation of substation voltage.In view of the above problems,considering the large number of distribution stations and the inconvenience of data collection,this paper proposes a data-driven method for evaluating the adequacy of reactive power resources in the substation area.Based on the base state model and sensitivity analysis fitting of the substation area,this method uses the low-voltage side voltage operation data of the substation area to draw the reactive Demand curve online and evaluate the adequacy of reactive power resources in the substation area from multiple dimensions,Realize differentiated analysis and practical online evaluation of reactive power resources in the substation area.Subsequently,an evaluation analysis of the adequacy of reactive power resources was conducted using a certain substation area as an example,verifying the effectiveness of the proposed method without relying on complex modeling.
