Abstract

The invention discloses a unit state monitoring and intelligent early warning method comprising the following steps: determining a first monitoring system used for monitoring the operation state of a water-turbine generator set, the first monitoring system comprising at least one type of monitoring variable; judging whether the current unit working condition data meets the working condition judgment condition corresponding to each type of monitoring variable or not; and when the current unit working condition data meets the working condition judgment condition corresponding to each type of monitoring variable, obtaining a type of detection result of each type of monitoring variable through a continuous increasing trend detection method according to the obtained monitoring record text of each type of monitoring variable. The invention also discloses a transformer state monitoring and intelligent early warning method and an auxiliary machine state monitoring and intelligent early warning method. According to the invention, the change trend of state monitoring data of different hydropower station equipment 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 state monitoring of a unit, a transformer and an auxiliary machine. Background technique [0002] Hydrogenerator sets, transformers and auxiliary equipment are important electrical equipment in hydropower stations. They directly affect the safe operation level of the hydropower station system. Once a failure occurs, it will cause huge direct and indirect losses. At present, the monitoring of the operation status of the equipment in the hydropower station (including hydroelectric generating units, transformers and auxiliary equipment, etc.) mainly adopts the threshold value early warning method and the trend early warning method based on manual analysis. [0003] (1) Over-limit value alarm method. By setting the limit value of the equipment monitoring point, such as upper limit value, lower limit value, etc., it can...
