【摘要】 针对目前输变电设备的维修技术,将风险评估引入输变电设备的维修决策中,建立了基于风险评估的维修方法,应用于输变电设备的基本技术框架。从经济风险和系统风险两方面出发,分别得到设备量化的各个风险指标。通过对系统风险进行经济性量化,将输变电设备故障造成的系统后果可以由相应的系统严重度来表示。最后的算例分析验证了该方法能够更加全面科学地评估风险,更加快速有效地进行维修决策。更多还原

【Abstract】 Given the current maintenance technology of electric transmission equipment,the risk assessment is introduced into the maintenance decision of electric transmission equipment,and a basic technical framework which is based on the maintenance method of risk assessment applying to the power transmission equipment is built.From two aspects of economic risk and systemic risk,each quantitative risk indicator of the equipment is gotten.By quantifying the systemic risk economically,the system consequence of electric transmission equipment outage can be presented by the corresponding system severity.This method has been proved to be more scientifically to assess risk and more quickly and effectively to make maintenance decisions by the final example analysis.更多还原
