Power distributing reactive optimizing compensation system based on GPRS and control method thereof

The invention discloses a reactive power optimum compensation system and a control method thereof of a GPRS-based distribution network. The compensation system of the invention comprises a combination control system and an intelligent upper computer (industrial computer) with collaborative optimization control, wherein, the combination control system coordinately controls TSC and DSTATCOM on the same compensation node by a hybrid dynamic control method, and can also realize the data remote-transmission of the system parameters of the node to the intelligent upper computer with collaborative optimization control by a GPRS wireless communication network; the intelligent upper computer with collaborative optimization control searches the optimum compensation node and the compensation capacity by utilizing a multi-machine collaborative reactive power compensation method and also sends an optimum control command to a combination compensation system which then realizes the local large-capacity and continuous reactive power compensation by classified TSC capacitance switching and continuous DSTATCOM compensation. The reactive power optimum compensation system of the invention effectivelysolves the defects of poor capacity of resisting disturbance and difficult networking, etc. of the existing reactive power compensation system, and also reduces the operation cost.
