The invention relates to the technical field of power
system monitoring, in particular to a
bus duct temperature and
humidity abnormity monitoring method, which comprises the following steps of S1, periodically acquiring temperature and
humidity data through a temperature and
humidity sensor, and performing data preprocessing to obtain processed data; s2,
mutation detection and
trend analysis are carried out according to the processed data, and
mutation data and trend data are obtained respectively; s3, according to the abrupt change data and the trend data,
a weighting strategy is adjusted in a self-adaptive mode; when the method is used, the credibility of data can be improved, the
noise and errors of the sensor can be effectively reduced, the adaptability of the
system can be improved, the data subjected to denoising and abnormal value
elimination can be used as high-quality input of
mutation detection,
trend analysis and
time sequence prediction, the accuracy of the whole temperature and humidity abnormity monitoring is improved, and the reliability of the
system is improved. And short-time
window detection and long-time
window detection are integrated, so that the accuracy of anomaly monitoring is improved,
false alarm caused by purely based on
mutation detection is avoided, and the response speed of the method is improved.
