Abstract: Based on the practice experience and incessant improvement these years, automatic voltage control(AVC) system in Jinhua power grid has achieved the threelevel cooperation with AVC systems in province power grid and county power grids. In order to monitor the state of the cooperation of the threelevel AVC systems, an AVC threelevel cooperation state monitoring software was designed and developed. Firstly, the cooperation mechanism of the threelevel AVC systems was analyzed. Then the data to be monitored and the functional modules of this software were determined. At last, the design and implementation of this software were introduced. Practice experience indicates that this software could provide useful reference to monitoring center, dispatching center and AVC system managers.
