Method and device for monitoring distribution transformer overload power outage based on metering automation system

Abstract

The invention provides a distribution-transformer heavy-load-and-overload power-off monitoring method based on a metering automation system. The method includes the steps that load data of distribution transformers is collected once every preset data collection moment, and whether the distribution transformers are heavy-load distribution transformers or overload distribution transformers is judgedaccording to the load data; power-off event information is obtained, the heavy-load distribution transformers and the overload distribution transformers are analyzed through the power-off event information, and power-off distribution transformers caused by heavy load and overload are screened out. According to the distribution-transformer heavy-load-and-overload power-off monitoring method basedon the metering automation system, distribution-transformer heavy-load-and-overload monitoring technology means can be greatly improved, real-time monitoring of the distribution-transformer load-raterunning state is achieved according to the data analysis means, monitoring efficiency, accuracy and reliability are greatly improved, and when distribution-transformer abnormal power-off reasons are analyzed, the power-off distribution transformers caused by the heavy load and overload can be accurately screened out, and defect processing of the power-off distribution transformers is effectively improved.

Description

technical field [0001] The invention relates to the technical field of metering automation, in particular to a method and device for monitoring a distribution transformer overload and power failure based on a metering automation system.
