An Index System to Assess Reactive Power Operation in High Voltage Distribution Network

The executing existing regulation for voltage/ reactive power management is scant of both quantitative criteria with strong operability and related index system to assess reactive power operation in power network,for this reason,an index system to assess reactive power operation in high-voltage distribution network is proposed.The proposed index system assesses reactive power operation of high-voltage distribution network in two sides,i.e.,the configuration of reactive power compensation capacity and control ability of voltage and reactive power.Using the proposed index system,the problems related to voltage and reactive power operation in high-voltage distribution network can be traced and the concrete main power transformer causing the problem can be tracked down,and then reactive control strategy of voltage/reactive power can be drafted.The application of the proposed index system in Yuhang high-voltage distribution network verifies the correctness and rationality of this index system.The proposed index system could be available for refined management of voltage and reactive power operation.
