Abstract

The invention discloses a transformer state monitoring intelligent early warning method. The method comprises the following steps: determining a second monitoring system for monitoring the operation state of a transformer; i-class monitoring parameters are obtained from the second monitoring system, and when the current unit working condition data meet working condition judgment conditions corresponding to the I-class monitoring parameters, a first-class early warning result is obtained through a continuous increasing trend detection method according to the obtained monitoring record text of the I-class monitoring parameters; the I-type monitoring parameters refer to data having a correlation relationship with the working condition data of the unit; acquiring II-class monitoring parameters from a second monitoring system, and acquiring a second-class early warning result set through a continuous increasing trend detection method according to the acquired monitoring record text of the II-class monitoring parameters; the II-type monitoring parameters refer to data which do not have a correlation relationship with the unit working condition data. According to the invention, the change trend of different hydropower station equipment state monitoring data can be intelligently analyzed, and the timeliness and accuracy of trend early warning can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of equipment monitoring, and in particular relates to an intelligent early warning method for transformer state monitoring. Background technique [0002] Turbine generator sets, transformers and auxiliary machines are important electrical equipment in hydropower stations. They directly affect the safe operation level of the hydropower station system. Once they fail, they will cause huge direct and indirect losses. At present, the monitoring of the running status of the equipment in hydropower stations (including hydro-generator sets, transformers and auxiliary machines) mainly adopts the threshold value warning method and the trend warning method based on manual analysis. [0003] (1) Alarm method for exceeding the limit value. By setting the limits of equipment monitoring points, such as upper limit and lower limit, etc., real-time detection of whether the state monitoring data of the equipment reaches the...
