Abstract: In allusion to the problems existing in the current management situation of reactive voltage and during the system operation of automatic voltage control (AVC), this paper used the innovated index system to carry out online evaluation, applied big data analysis and cooperated with three-level dispatching management, by optimizing AVC control strategy, increasing the coordination control between wind power and thermal power, intensifying defects closed loop control, reinforcing voltage monitoring adjustment and adjusting reasonable operation mode etc methods. From the respects of management tools and technical measures, the system improved the management level of reactive voltage, realizing the time-sharing and substation-sharing precise control of reactive voltage.
Key words: reactive voltage; automatic voltage control; power factor
