In order to study the accident risk of gas power plant, and through the nearly ten years of statistical analysis of gas power plant accident, failure to get the presence of risk factors of gas power plant. Use explanation structure model, structural analysis of the identified risks, through expert for each system within the relationship between the risk factors of comparison, identify the gas leakage at the risk and risk factors, step by step under the top building structural relationships. Secondly, using fuzzy analytic hierarchy process to evaluate the risk factors quantitatively, the gas system is the main risk. Finally, the risk of the gas leakage accident is evaluated. Based on the case of the Jing Feng gas power plant, the safety countermeasures are put forward to provide guidance for gas generation enterprises.
