Abstract

The invention discloses a multisource and multi-parameter fusion-based electric transmission / transmission equipment state abnormal mode recognition method and device. The method comprises the following steps of: obtaining original monitoring data; respectively sorting various pieces of state quantity data according to a time sequence; judging whether each piece of state quantity data is candidateabnormal data or not; when the state quantity data is the candidate abnormal data, generating a candidate abnormal data sequence at the current moment; and when the candidate abnormal data sequence does not accord with a preset normal data clustering feature, obtaining a plurality of monitoring data sequences in a first time period which comprises the current moment, and judging whether electric transmission / transmission equipment is abnormal or not according to the plurality of monitoring data sequences. The multisource and multi-parameter fusion-based electric transmission / transmission equipment state abnormal mode recognition method and device are capable of effectively reducing the algorithm complexity and space required for data storage and calculation, and can be used for rapid and effective recognition of various electric transmission / transmission equipment abnormal states.

Description

technical field [0001] The invention relates to the technical field of signal and information processing, in particular to a method and device for identifying abnormal patterns of power transmission and transformation equipment based on multi-source and multi-parameter fusion. Background technique [0002] Power transmission and transformation equipment is the most important power system equipment, so its condition monitoring and fault diagnosis have always been very concerned technical fields. At present, most online monitoring devices use a certain standard threshold to judge the status of power transmission and transformation equipment, and only when the monitoring data exceeds a certain evaluation value, an alarm signal is issued. Due to the differences in the operating environment of each power transmission and transformation equipment and the detection principles and acquisition accuracy of different devices, the threshold value applicable to a certain sensor on a cert...
