摘要

将状态检修与大面积停电问题结合起来,提出一种基于状态检修(condition based maintenance,CBM)的N-k故障在线辨识方法:根据状态检修实时数据建立设备的故障可能性模型,应用功能组(functional group,FG)理论及相关改进后的搜索方法实现N-k故障路径的在线搜索及筛选,并根据电网实际运行方式以及状态检修的监测情况,建立了N-k故障的概率模型。最后,利用C++语言实现了所提方法,并以安阳电网的3个变电站为例验证了方法的正确性。

Abstract:

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