北美可靠性风险评价指标及应用分析

为了支撑我国可靠性标准的改进和对执行过程的监督，需要建立完善的可靠性评价指标。首先总结了北美大电力系统的可靠性标准体系及标准驱动指标(Standards Driven Index, SDI)中标准的选择原则。随后，剖析了SDI指标的设立目的、发展流程、性能指标模型和数据来源等方面，结合案例重点分析了风险指标CP-1和影响指标CP-2的应用情况和改进建议。最后，通过对我国现阶段可靠性标准制定和风险管理现状分析，指出我国在可靠性标准体系、事件分析和数据管理方面还有待改善。建议完善并扩大可靠性指标领域，加强事件跟踪分析并建立统一的数据库，以降低电力系统风险。

North American reliability risk assessment indicators and application analysis

In order to support the improvement of China''s reliability standards and the supervision of the implementation process, it is necessary to establish a sound reliability evaluation index. Firstly, this paper summarizes the reliability standard system of North American power system and the selection criteria for the Standards Driven Index (SDI). Subsequently, the purpose of the establishment of SDI indicators, development process, performance indicators and data sources are analyzed. After that, the application of risk indicators CP-1 and impact indicators CP-2 and suggestions for improvement are specifically analyzed with the case study. Finally, in view of the current situation of the reliability standard and risk management system in China, it is pointed out that China still needs improvement in terms of reliability standard system, event analysis and data management. It is recommended to improve and expand the field of reliability indicators, strengthen incident tracking analysis, and establish a unified database to reduce power system risks.
