基于继电保护的隐性故障诊断策略研究

Research on Hidden Fault Diagnosis Strategy Based on Relay Protection

为增强变电站的隐性故障诊断能力,本文提出了一种基于多维变量的智能变电站隐性故障诊断策略,通过构建继电保护隐性故障诊断体系,实现了对隐性故障的辨识与定位。在实例分析中,以某智能变电站的实际运行数据为输入,验证了本文提出故障诊断策略的科学性、有效性、合理性、可靠性。

To enhance the implicit fault diagnosis ability of substations,this paper proposes an intelligent substation implicit fault diagnosis strategy based on multidimensional variables.By constructing a relay protection implicit fault diagnosis system,the identification and localization of implicit faults are achieved.In the case analysis,the scientific,effective,reasonable,and reliable fault diagnosis strategy proposed in this paper was verified by taking the actual operation data of a certain intelligent substation as input.
