| 摘 要： | 采用元件可靠度和系统可靠度两个可靠性指标，提出功效评估法：通过硬件模块、接口模块、功能模块、功效模块对继电保护及控制系统进行建模。针对二次系统对一次系统的产生的功效，提出一次系统的典型功能事件，并分别通过串并联网络法定量评估二次系统的可靠性。深入到元件层面对硬件模块进行重要度分析并重新排序，从而有针对性的发现系统薄弱环节，提高二次系统的可靠性。

| Abstract: | Two reliability indices, component availability and system availability, are illustrated. Reliability model of protection and control systems is created by a system effectiveness approach including hardware module, interface module, functional module and effective module. Typical functional events are demonstrated based on the effectiveness on the primary systems. And series-parallel method is used to quantitatively evaluate the reliability of protection and control systems. Components importance analysis i... |
