摘要
配电终端的可靠性对配电自动化有效运维至关重要,结合故障树分析法与比例分摊原则,提出了适用于配电终端失效研究的一种方法。该方法通过分析各配电终端各模块工作与失效机理,建立配电终端的故障树分析模型,采用故障树分析法推导顶端事件失效计算公式;根据失效分摊法计算出各模块对系统失效的贡献比例,并据此识别配电终端的薄弱环节。最后以重庆某地区配电终端现场运行数据为样本,验证了该方法的有效性。
The reliability of distribution terminal is crucial for the effective operation of distribution automation.Combined with the principle of fault tree analysis and the principle of proportion allocation,a method for failure analysis of distribution terminal is presented.Through the analysis of the distribution of the terminal module and failure mechanism,it establishes the terminal power distribution fault tree analysis model,and based on the fault tree analysis method,it derives the top event failure calculation formula.According to the ineffective allocation method,the system failure contribution ratio of each module is calculated,and it can tell the weak links of distribution terminal.Finally,the validity of the method is verified,based on the field operation data of the distribution terminal in a certain area of Chongqing.
