Abstract

The invention discloses a system of performing early warning on faults of transformers. The system includes a plurality of data monitoring nodes, a data acquisition unit, a data analysis unit, a faultdiagnosis unit and a fault early warning unit, wherein each data monitoring node includes a plurality of monitors and each monitor is used for monitoring the state parameters related with the operation state of an owned transformer; the data acquisition unit is used for acquiring all the state parameters related with the operation state of the owned transformer; the data analysis unit is used forperforming data analysis on all the state parameters of each transformer to determine the performance level of each state parameter; the fault diagnosis unit is used for determining the operation standard of each state parameter, performing scoring on the performance level of each state parameter according to the operation standard of each state parameter, and determining whether each transformerhas a fault and determining the fault type according to the scores of at least one state parameter of all the state parameters; and the fault early warning unit is used for reporting the identifier and the fault type of each transformer to a remote monitoring center when determining that the transformers have faults.

Description

technical field [0001] The present invention relates to the technical field of transformer faults, and more specifically, to a system and method for early warning of transformer faults. Background technique [0002] It is of great significance to the power system to realize the intelligent online monitoring and early warning of the transformer in the substation through the automatic online detection technology of the smart grid. Through the online monitoring and early warning of the transformer, it will greatly improve the safe operation of the substation equipment. [0003] At the earliest, since the main transformer equipment in the operating substation cannot be detected online in real time, it is almost always repaired and repaired after a problem occurs, which not only affects the quality of power supply, but also increases the damage rate of the equipment. With the development of science and technology, the transformer monitoring system is gradually taking shape, but m...
