基于三态数据的电网在线综合故障诊断

On-line Comprehensive Fault Diagnosis of Power Grid Based on Three-state Data

摘要: 提出了一种基于三态(稳态、动态、暂态)数据的电网在线综合故障诊断方法。首先从数据特性和调度自动化现状出发,分析了利用三态数据进行在线故障诊断的必要性;其次,从在线故障诊断的正确性、实时性和全面性3方面入手,提出了多源信息的数据挖掘和协同处理技术;最后,展望了电网在线故障诊断未来的发展方向。

Abstract: An on-line integrated fault diagnosis method of power grid based on three-state（steady,dynamic and transient state） data is proposed.Firstly,proceeding from the data characteristic and the status quo of dispatch automation,an analysis is made of the necessity of on-line fault diagnosis using the three state data.Secondly,starting from the aspects of accuracy,real-time,comprehensiveness of on-line fault diagnosis,a technology of data mining and co-processing based on multi-source information is proposed.Lastly,a look-ahead of the future developing direction in the field of on-line fault diagnosis is given.
