Abstract

The invention discloses a transformer early warning method for an operation and maintenance system, relates to the technical field of power systems, and solves a technical problem of recognizing the abnormal condition of a transformer. According to the nominal parameter of the transformer, transformer operating condition data measured by the operation and maintenance system, and transformer operating condition data measured by a manual tour inspection way, the method calculates the temperature alarm coefficient and the current difference ratio of the transformer so as to calculate the alarm value of the transformer, and determines the operating state of the transformer according to the alarm value of the transformer so as to timely identify the abnormal operating conditions of the transformer and data acquisition quality anomalies. The method provided by the invention can help an operation and maintenance worker discover equipment defects timely.

Description

technical field [0001] The invention relates to power system technology, in particular to a technology of a transformer early warning method for an operation and maintenance system. Background technique [0002] With the continuous expansion of the scale of the power grid, the workload of power grid monitoring and operation and maintenance is increasing. The power system operation and maintenance inspection system can effectively improve the level of power grid monitoring and equipment automation management, and reduce the workload of operation and maintenance personnel. [0003] During the inspection process, the original inspection method is to manually fill in the report, and then report the summary method, and the defect information of the transformer equipment is registered and stored in the warehouse. Problems, the abnormal operation of the transformer equipment cannot be detected in time, and an early warning is issued. Contents of the invention [0004] In view of...
