摘要
提出了超高压智能变电站中的主变压器、开关、避雷器等主设备智能化及其智能组件的配置策略、综合故障诊断的实现方式;通过信息共享和数据综合分析,实现了对变压器、断路器、避雷器等被监测设备的分析、评估和预报,判断故障性质、类型、程度和原因,以及故障发生和发展的趋势,提出排除故障的建议措施,为运行、检修人员提供及时的参考信息。研究成果已在500kV智能变电站改造工程中成功应用。
A new intelligent strategy of transformer, circuit breaker, arrester for extra-high voltage smart substation, and their intelligent component configuration as well as the implemented mode of integrated fault diagnosis are proposed. Analysis, evaluation and prediction of transformer, circuit breaker and arrester, etc. monitored equipments are implemented by sharing information and synthesizing data from main equipments so that the fault property, type, degree, cause and trend can be judged. Suggestion for removing failure is put forward so as to provide latest reference information for operating personnel and maintainer. Research results have been successfully applied to modernization of 500 kV smart substations.
