Abstract
Provided is a transformer station measured data abnormity warning method which summarizes and concludes a criterion capable of determining the abnormity of measured data according to various data characteristics at the time when measured data abnormity appears in a user transformer station, and which gives a corresponding alarm and a trip-out instruction in a preset specific case when the criterion is satisfied. The method may monitor the data of all measuring points in the transformer station in a unified way. When equipment or man-made data abnormity appears at a certain measuring point, an alarm can be given immediately to warn operators in the transformer station, a data abnormity reason can be automatically acquired and information is transmitted to a power company main station at a distant place. The method may automatically turn off a breaker in a faulted line within five minutes after the data abnormity appears in order to prevent long-time measured data abnormity and contribute to electric energy compensation in the future. The method effectively prevents great consequent loss of electric charge of a power company, timely gives the alarm and activates trip-out, and contributes to abnormality positioning in advance for the power company.
