Reactive voltage automatic control system of regional power grid

The invention relates to a reactive voltage automatic control system of a regional power grid which is applied to the technical field of power; the reactive voltage automatic control system of the regional power grid comprises a database module, a communication module, an analysis and calculation module, a graphic display module, a report management module and a system management module, wherein the communication module receives the actually measured data which is forwarded by a data acquisition and control system, sends the actually measured data to the analysis and calculation module, and simultaneously stores the actually measured data to the database module; the analysis and calculation module analyzes and calculates the actually measured data, forms a reactive voltage control strategy, issues the reactive voltage control strategy through the communication module, simultaneously transfers the reactive voltage control strategy to the graphic display module through the communication module, and displays the calculational analysis and the control results; the report management module inquires, displays and prints the control result through the communication module; and the system management module realizes the management of the whole system through the communication module. According to the reactive voltage automatic control system of the regional power grid, all automatic operations in the whole process can be controlled, the work intensity of a field operator can be greatly reduced, and the production efficiency is improved.
