Probability Analysis Model and Risk Assessment of N-k Contingency Based on Condition-Based Maintenance

摘要：

Combining condition-based maintenance (CBM) with large-area power-failure,an N.k contingency on-line identification method based on CBM is proposed in this paper.According to real-time data of CBM,a failure possibility model for equipments is built,and the online searching and screening of N.k contingency path are implemented by use of the theory of functional group and modified searching approach; based on utility theory and monitoring results of CBM,risk assessment model of N-k contingency is established.Finally,the proposed method is realized by C++language.Taking three substations in Anyang power grid for example,the correctness of the proposed method is verified.
