【Abstract】 In the development of a new integrated control set for voltage and reactive power in substation, some improvements for the traditional nine-zone diagram are performed. After the derivation of the formulas of the control variables, in which the relation between reactive power of capacitor and voltages is considered, the operating status is meticulously divided into more zones, and the corresponding control strategy is brought about. In the hardware of this set, the 80C196KC single chip microcomputer system and In System Programmable (ISP) device is adopted to provide a friendly interface; in the communication the CAN bus protocol is applied. The result of simulation tests shows that this method is correct and superior.更多还原
