The invention discloses a power grid security risk influence factor analysis method, which comprises the following steps of: firstly, analyzing an accident mechanism from four aspects of human factors, equipment factors, management factors and environmental factors by applying a'cognition-constraint 'model, and secondly, constructing a proper accident tree model to systematically sort security risk factors, and explaining the correlation effect among the influence factors, and summarizing the accident occurrence rule by quantifying the structural importance of each event. According to the method, the power grid safety risk influence factors are taken as research objects, the relationship among the influence factors and the corresponding accident occurrence rule are deeply analyzed, and reasonable suggestions are provided for scientifically and reasonably avoiding the occurrence of similar accidents and building a safety power grid. 本发明公开了一种电网安全风险影响因素分析方法，首先应用"认知-约束"模型，从人为因素、设备因素、管理因素、环境因素4个方面对事故机理展开分析，其次构造合适的
