Abstract

Abstract:

To improve the emergency management level of coal-fired power generation and ensure the safety and stability of the coal-fired power industry, an index system for the evaluation of the emergency management ability of coal-fired power plants was established in this paper from the aspects of emergency preparedness ability, emergency prevention and early warning ability, emergency response ability, emergency support ability, and emergency recovery ability. An improved fuzzy comprehensive evaluation method based on entropy weight was constructed, and the safety emergency management ability of a typical coal-fired power plant was evaluated systematically. Finally, measurements and suggestions for optimizing safety emergency management were proposed. The results show that the weight of the evaluation indexes for the emergency management ability of coal-fired power plants taper off as emergency recovery ability (0.269), emergency support ability (0.227), emergency preparedness ability (0.197), emergency prevention and early warning ability (0.172), and emergency response ability (0.135). The fuzzy comprehensive evaluation model can effectively solve the difficulty of evaluating complex problems with multiple factors and levels and improve the objectivity and scientificity of emergency management evaluation in coal-fired power plants.

Key words: entropy weight, fuzzy evaluation, index system, coal-fired power generation, safety emergency management
