Title: Research on Reactive Compensation Principle of Configuration Optimization in Distribution Grid
Abstract: The paper carries out the optimization of the principle of reactive power current configuration,that would make the reactive power compensation of the distribution power grid more economic and more effective,and the distribution power grid operation would be more economic.Firstly,the paper confirms loss reduction as the goal of the reactive power compensation optimization on the basis of establishing the reactive power compensation cost model and analyzing the investment of reactive compensation.Secondly,the paper establishes the calculation models of the power loss caused by the reactive power transmission of the components in distribution power gird,and gives the sensitivity analysis for the loss reduction.Meanwhile,the paper builds the cost-benefit model of the reactive power compensation,proposes the optimal power factor through analyzing the costeffectiveness of the reactive compensation,and optimizes the reactive power compensation principle of the transformer substation and distribution transformer combining with the hierarchical balance optimization of reactive power principle.Finally,the rationality and economy of the optimized principle is verified based on the analysis of the reactive power compensation configuration for typical examples.
