摘要
为提高二次虚回路故障精准度,提出对基于数字孪生技术的开关操作箱二次虚回路故障精准定位方法。根据当前的定位需求,先明确二次虚回路故障特征。然后采用多元件的方式,打破传统定位方法的覆盖范围限制,设计多元件自检告警BPA定位结构,并构建数字孪生开关操作箱二次虚回路故障定位模型,最终采用举证测验处理的方式来实现故障定位。测试结果表明:针对选定的6个测试区域,新方法的故障定位误动次数被控制在5以下,说明在数字孪生技术的辅助下,新方法更具有应用价值。
To improve the accuracy of secondary virtual circuit faults,a precise positioning method for secondary virtual circuit faults in switch operation boxes based on digital twin technology is proposed.Based on the current positioning requirements,first clarify the fault characteristics of the secondary virtual circuit.Then,a multi-component approach is adopted to break the coverage limitations of traditional positioning methods,design a multi-component self checking alarm BPA positioning structure,and construct a secondary virtual circuit fault positioning model for the digital twin switch operation box.Finally,an evidence-based test processing method is used to achieve fault positioning.The test results indicate that for the selected 6 test areas,the number of false positives for fault location of the new method is controlled below 5,indicating that with the assistance of digital twin technology,the new method has more application value.
