Centralized Control System for the Regional Grid＇s Reactive Voltage Optimized Operation

Under the conditions of guaranteeing the safety operation of the power grid and all the equipment involved, the centralized control system for the regional grid＇ s reactive voltage optimized operation helps realize the optimized control for the reactive voltage from the angle of the whole grid, rationalizing the input of the reactive power compensation and realizing the reactive hierarchy direct balancing and stabilizing the voltage. The system minimizes tbe adjusting times of the main transformer＇s tapping switches, reduces the power transmission loss, and raises the automation capability of the grid, therefore enhances the safety and stability of the power system＇s operation, and comprehensively improves the voltage quality. This paper expounds the functions of the system and the technical solutions.
