Research on Construction Method for Blackout Fault Set Based on Weighted Power Flow Entropy and Coupling Branch Intermediate Index
摘要
Abstract
With the expansion of power grid interconnection scale,the probability of power blackout caused by cascad-ing faults in power grid increases.Therefore,the construction of a cascading fault set is an effective measure to prevent blackout.First,the set of fault branches that have a significant impact on the stable operation of power grid is studied.Secondly,a weighted power flow entropy calculation method is studied to quantitatively evaluate the operation status of power grid.Thirdly,combined with the PSD-FDS simulation software,a construction method for the blackout fault set based on weighted power flow entropy and coupling branch intermediate index is proposed,which can accurately reflect the dynamic process of power grid faults by taking into account changes in both the power grid's structure and its status.Finally,a regional power grid is taken as an example to verify the correctness and effectiveness of the proposed method.关键词
