基于连续潮流模型的电网自组织临界性的探讨

建立了一个基于连续潮流电网连锁故障模型,通过引入了一个切负荷控制模块,有效的选择切负荷点、切负荷量,模拟仿真了电网大停电事故的发生过程。结果表明:该模型不但能更有效地揭示电网大停电事故机理中自组织临界性,而且可以有效地防止大停电事故的发生,降低大停电发生的风险。

Discussion on the Network Self-Organization Criticality Based on Continuous Power Flow Model

An electric network interlocking fault model based on continuous powerflow is set up. By drawing to a switching load control module,select an efficient switching load point and switching load quantity. The analogy simulates the procedure of large area power failure of the network. The result shows that the model can not only reveal the selforganization criticality of the large area power failure mechanism more efficiently,but prevent large area power failure,reducing the risking of large area power failare.
