摘　　要：通过对3种电力系统安全风险评估方法的分析,认为现代电力风险评估体系能将更多的影响因素纳入评估流程,定量地抓住事故的可能性,引入反映经济因素的风险指标,实现对设备状态及风险的综合性、系统化的分析,为项目确定、检修或策略的变更等提供理论基础,可提高企业资产管理。实例计算结果表明,风险状态评估经济效益明显。By analysis of three methods of safety evaluation in power system,the paper believes that power risk management system can bring more influencing factors into evaluation procedure,hold back accident possibilities in nemberical quantities and introduce risk indexes influencing economic factors so as to comprehensively and systematically analyze equipment status and risks,which provides theoretical basis for project determination,overhaul and change of strategies and can enhances enterprise assets management.The calculation example indicates that the risk status evaluation has apparently achieved economic benefits.
