United accident-prevention rehearse method for provincial and city power system

Abstract

The invention suggested combination anti-accident maneuver method of provincial and prefectural two-stage power system, pertains to the power system dispatching automation and simulation technology. First of all provincial power network dispatching centers and prefectural network dispatching centers automatically generate initial power flow parameters according to their own power network real-time data, the provincial dispatching centers send the data to the prefectural dispatching centers; the prefectural dispatching centers correct the prefectural power network flow distribution after receiving the parameters, after the power network disturbance occurred, the provincial dispatching centers and the prefectural dispatching centers respectively send their flow parameters data after being changed to the other party, and correct the respective states. The method has the advantages that: the provincial and the prefectural dispatching centers can reflect mutually the impact of their own power network model changes on the other side, and ensure the fidelity of the combination anti-accident maneuver; only a small number of key information is exchanged between the provincial and the prefectural dispatching centers; and the provincial and the prefectural dispatching centers can independently conduct the combination anti-accident maneuver, which is a kind of decoupling mode and has a in high availability of their own system.

Description

technical field [0001] The invention relates to a joint anti-accident exercise method for provincial and local power systems, and belongs to the technical field of power system scheduling automation and simulation. Background technique [0002] The power grid is composed of multiple regional power grids interconnected as a whole, and the impact on the power grid after an accident occurs is global; while the dispatch and control of the power grid are usually hierarchical, hierarchical, and independently carried out. Provincial and regional dispatch centers are very important two-level dispatch, and dispatchers at these two levels need to coordinate and cooperate with each other in daily operation dispatch and accident handling. The dispatcher training simulation system (DTS) is an important technical means for training dispatchers and anti-accident drills. [0003] Limited by the progress of computer technology and distributed computing research, the joint anti-accident dril...

AI Technical Summary

Problems solved by technology

[0009] Among them, Option 1 is the method commonly used at present, using independent provincial and regional DTS to conduct exercises, and then relying on manual adjustments, it can only achieve an effect similar to a sand table demonstration, without coordination between power grids, the degree of fidelity is not high it is good

Scheme 2 has something in common with the present invention, but this paper only discusses its advantages and disadvantages, does not provide specific implementation technology, and does not actually realize

Option 3 is an idealized method, but it has strict requirements on communication conditions, difficult model maintenance, serious waste of computing resources, and is not practical
