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.
