Abstract

The invention provides a method and a system for analyzing and processing events of a three-winding main transformer based on multi-source data. The method comprises the following steps: performing fault judgment and processing according to action information and time mark information of each monitoring device of the main transformer; performing preliminary judgment on internal and / or external faults of the main transformer according to the protection action type; corresponding historical equipment data and field equipment data are extracted according to the fault type of the main transformer for difference comparison, and the fault of the main transformer is further determined and processed based on the difference comparison result; and performing fault judgment and processing on the main transformer equipment, the main transformer control loop and background signals based on the health degrees of the main transformer primary and secondary equipment. According to the method, the related data of each part of the main transformer is acquired, and corresponding fault judgment and processing are respectively performed, so that the analysis accuracy is improved, the main transformer event fault analysis process is combed, and the fault finding time is greatly shortened.

Description

technical field [0001] The invention belongs to the technical field of grid dispatch automation, and in particular relates to a method and system for analyzing and processing events of a three-winding main transformer based on multi-source data. Background technique [0002] With the continuous advancement of unmanned substations, staff need to go to the site to check in time after a substation event occurs, but most of the substations are located in remote areas, which makes it take a long time for staff to arrive at the station. In addition, problems such as bad weather will hinder the on-site inspection work of the staff. [0003] At present, after the light gas of the transformer is activated, according to the latest regulations, after the light gas (including the main body and the tap changer) alarms, it is necessary to apply for a power outage to inspect and dispose of the relevant transformers in accordance with the emergency defect handling process. On-site inspecti...
