Research on Safety Evaluation Method of Hydropower Plant based on Extension Theory

[摘要] The theory of extenics is used to evaluate the safety of hydropower plants. The theory of matter element analysis and the theory of extension set are introduced into the evaluation, applying the concept of extenics, create a set of matter element analysis model, structure a set of evaluation index system for safety of hydropower plants. By calculating the extension correlation degree between each index and each evaluation grade, the safety of the hydropower plant is evaluated. At the same time, the weight coefficient is determined by the analytic hierarchy process. In the realization of comprehensive and quantitative evaluation, ensure the objectivity of the whole process of evaluation and avoid the influence of human subjective factors.
