Reactive Power Voltage Control Based On AVC In Regional Power Grid

Power system operating voltage depends on the balance of reactive power, if the lack of reactive power within the system will enable lower voltage level, the case of system disturbances, it is possible the voltage below the threshold voltage, while the collapse of catastrophic accidents of the system reactive power and voltage control in power systems has also become an important research content. This article focuses on analysis of area grid AVC devices based on the entire network reactive power and voltage control, the current emphasis on the more mature regions at home and abroad, and the whole network AVC control theory, engineering, analysis and comparison of the implementation of programs, including the independent AVC devices are now controlled strategic analysis, distributed control system effectiveness analysis of reactive power and voltage regulation and control strategy to improve on the more mature of the whole network at home and abroad AVC program conduct a study to propose adapted to large-scale grid systems to municipal control over the implementation of the whole network AVC the means to do theoretical preparation. According to area, the actual size of grid characteristics that suit the layout of the grid the whole network in area AVC system control mode, control strategy,and as a regional power grid NingBo analysis and appraisal examples.
