Risk Element Transmission Model for Power Grid Engineering Based on Covering Rough Set
Li Zhu · East China Electric Power · 2012
A new approach to power grid engineering risk analysis is proposed based on covering rough set and neighborhood classifier theory in this paper.At first,the concept and principles of the model is introduced,and historical data from risk information system of the power grid engineering are normalized.Then the neighborhood classifier with high precision is used to classify the historical data in order to construct the knowledge bases for estimating their average testing accuracy.Finally,the bases with higher precision are chosen to forecast the probability distribution of power grid engineering under a new case of risk elements in order to assess the risk of the project.Furthermore,a case analysis demonstrates the feasibility and efficiency of the model.
