摘要提出一种由点及面的建模思路及相关性分析的无功规划方法。该方法从无功平衡的角度将影响无功优化配置率的特性参数分为影响程度小(LI)和影响程度大(MI)的两类,利用LI类特性参数建立20 kV城市电缆网的“点模型”;而MI类特性参数则用来对“点模型”进行多维度拓展,使分析工作能较强覆盖不同特性的线路。进而采用相关性分析的方法进行20 kV城市电缆网无功配置率的优化研究,得出适用于不同负荷特性的配变台区的最优无功配置率参考范围,以解决目前对20 kV配电网无功配置率研究不足、指导原则中配置区间过于笼统及缺乏差异性等问题,也避免了针对各线路逐一进行无功优化规划的通用性不足的问题。算例结果说明了该方法的有效性。

Abstract：A reactive power planning method,based on the modeling approach from points to face and the correlation analysis,is put forward in this paper.From the perspective of reactive power balance,the characteristic parameters which influence the optimal rate of reactive power allocation (RPA) are divided into two categories.The ones that have less influence (LI) are used for creating the “point model” of the 20 kV urban cable network.And the others that have more influence (MI) are available for developing the point model toward multiple dimensions so that the analysis can cover different features lines.Then,with the optimization research on the rate of RPA in the 20kV urban cable network by the correlation analysis,the optimal referential range of the RPA rate which can be applied to distribute-electricity transformer district with different load characteristic is worked out.The article provides solutions for the limited research on the optimal research on the rate of RPA in 20 kV distribution network and the over-generalized guidelines neglecting the differences.Also,it avoids the limited generality of the other approaches considering every feeder’s optimal reactive power planning.The effectiveness of the method is verified by example results.
