Integrated control of voltage and reactive power based on monitoring system

Voltage and reactive power integrated control (VQC) is an effective means to increase rate of qualified voltage,reduce grid losses,and improve the system stability. A comparative analysis on the advantages and disadvantages of the multiple ways and control strategy is conducted.Upon this, a new method based on predict algorithm and local monitoring system is presented,and implementation of the method is also described.Because of the complicated operation mode,the object-oriented design thought is used to realize the control function of multiple substation and operation mode.
