| The social demand for electricity with economic prosperity and progress of contemporary science and technology, power application field is more and more big, equipment manufacturing technology is developing rapidly, many power enterprises successively in the country established, the size of the plant throughout all parts of the country. According to the energy difference and types of power are mainly thermal power, wind power, photovoltaic power plants, hydropower and nuclear power, the power is still the main power resource in China, the safety of electric power production is foundation of stable development of the industrial economy. To strengthen the power production safety foundation, to ensure the safety, stability and economic operation of the power plant, and reduce the production accident of the power plant, has important significance.Based on the more than more than 100 different types of power plants (not including hydropower, nuclear power, the same below) the safety analysis and evaluation processes, characteristics of different types of dangerous existing power plants are summarized.electric power enterprise in China at present, the main safety analysis and evaluation of preliminary hazard analysis (PHA), inspection method, method of analogy and simulation analysis of accident consequences, These evaluation method in the evaluation of power plant plays an appropriate role. After the heavy use of these assessment methods, arguing that existing methods based on fuzzy analytic hierarchy process to evaluation process could be further improved, the results more objective. Explore the feasibility of its application in the power plant engineering and significance, and an applied analysis of the advantages and disadvantages of different evaluation methods, to mprove the quality of evaluation, reduce the risk of accident.
