Reactive voltage control simulation system and method based on power grid regulation and control integrated mode

Abstract

The invention discloses a reactive voltage control simulation system and method based on a power grid regulation and control integrated mode. The reactive voltage control simulation system based on the power grid regulation and control integrated mode comprises a simulation service system and a control system. The simulation service system is used for receiving external control and disturbance, simulating the regulation of power grid equipment, simulating the load flow changes of a power grid, generating real-time simulation power grid data, storing, managing and distributing the real-time simulation power grid data, and supplying the real-time simulation power grid data for the control system. The control system receives the real-time simulation power grid data from the simulation service system and stores the real-time simulation power grid data, formulates a simulation power grid control strategy, generates a control instruction and sends the control instruction to the simulation service system. According to the reactive voltage control simulation system and method, an AVC system and a DTS system can conduct closed-loop control simulation on the power grid according to an actual power grid operation electricity generation load curve in continuous time periods, and the defect that when an existing AVC system conducts verification and analysis on the control strategy, the regulation condition which may occur is not taken into consideration is overcome.

Description

technical field

[0001] The invention relates to the technical field of automatic control and simulation of electric power system dispatching, in particular to a reactive power voltage control simulation system and a method thereof based on an integrated mode of power grid regulation. Background technique

[0002] Under the integrated regulation mode, for the regional power grid, the automatic reactive power and voltage control system (AVC) is one of the most important automatic control systems. As a real-time control system, AVC has very high requirements on operation reliability and safety. Before the AVC system is put into closed-loop control operation, or before a substation is put into closed-loop control, an effective method is needed to analyze and verify the strategy given by the AVC system to confirm the rationality and safety of the closed-loop control strategy given by the AVC system And correctness, this kind of verification link is indispensable, and it is an im...
