Abstract


Boiler equipment as one of the three main power plant , which largely determines the security situation in the security of the entire plant operation . Safety evaluation technology as modern safety management model, many power plants will fully understand the boiler system status, security infrastructure , weaknesses and potential accidents and to play an active role to govern . Boiler safety evaluation of the entire power plant safety evaluation of an important part of the boiler safety evaluation method research has important theoretical and practical significance. In this paper, a multi-level fuzzy comprehensive evaluation model for boiler safety evaluation , first from the power plant boiler equipment status , operating conditions and technical management of a comprehensive analysis of three aspects that affect the safe operation of boiler safety conditions and risk factors and on this basis, the establishment of a scientific and reasonable evaluation for online boiler safety evaluation index system, the evaluation index system is divided into layers containing class , the class system layer and layer hierarchy of specific indicators , and then gives layers of the index system method for determining the index weights , and according to the different types of indicators , specific indicators were given various types of indicators layer method for determining the membership function , then the use of fuzzy theory , a reasonable choice for fuzzy fuzzy synthesis operator comprehensive evaluation results obtained vector , then the fuzzy comprehensive evaluation vector analysis, from the most dangerous factors have started to consider using binary tree classification algorithm to determine the current state belongs boiler safety level , give the final evaluation results , a numerical example analysis verified the effectiveness and feasibility of the method . Finally, based on the above method in MATLAB GUIDE as a platform , the design ' of the boiler safety evaluation system software.
