Abstract

The present invention provides a transformer monitoring system and method. The transformer monitoring system comprises a gas in oil chromatography on-line monitoring unit, a micro water in oil monitoring unit, a temperature monitoring unit, a partial discharge monitoring unit, a grounding current on-line monitoring unit, a transformer and on-load tap changer vibration monitoring unit and a master station computer. The transformer monitoring system and method provided by the present invention can monitor and diagnose the faults of a transformer by various monitoring units and monitoring methods, thereby improving the monitoring accuracy.

Description

technical field [0001] The invention relates to the field of power system transformers, in particular to a transformer monitoring system and method. Background technique [0002] With the advancement of west-to-east power transmission, north-south mutual supply, and national networking, the scale of my country's power grid and the scale of power transmission are constantly expanding, and grid security issues have become increasingly prominent. The "8.14" blackout in the United States and Canada, the "11.4" blackout in Western Europe and other internationally influential blackouts in recent years have caused huge economic losses and produced adverse social impacts. According to the statistics of power grid accidents during the "Eleventh Five-Year Plan" period in my country, power equipment failures account for the first cause of power grid accidents. Therefore, the safe operation of power equipment is the first defense system to avoid major accidents in the power grid, and t...
