Monitoring method based on transformer station digital model

Abstract

The invention relates to a monitoring method based on a transformer station digital model. The method for localizing fault equipment comprises the following steps: (1), model establishment; to be specific, establishing an IFC informatization model according to a transformer station and specification parameters of all devices in the transformer station; (2), fault analysis; to be specific, carrying out an analysis and processing according to the operation data of all devices in the transformer station to obtain fault information of all devices in the transformer station; and (3), fault localization; to be specific, mapping the fault information to a corresponding IFC informatization sub model of each device in the IFC informatization model. Compared with the prior art, the IFC informatization model of the transformer station is established to carry out panoramic monitoring on the transformer station; and because the fault information of the transformer station is mapped to the sub models of all devices in the IFC informatization model, the fault information can be watched visually, so that the maintenance staff can carry out fault elimination conveniently.

Description

technical field [0001] The invention relates to a substation maintenance technology, in particular to a monitoring method based on a substation digital model. Background technique [0002] Since the concept of smart grid was introduced from abroad in the 1970s, a large number of digital substations using the IEC61850 standard system have been put into operation. The construction of domestic digital substations has been strongly supported and promoted by national policies and is developing in depth. At present, there are hundreds of digital substations that have been built and put into operation at home and abroad. The State Grid Corporation has approved dozens of the first and second batch of intelligent substation projects, and China Southern Power Grid has approved dozens of intelligent substations under construction. Despite this, the construction of intelligent substations still faces many problems: 1) Although the intelligent substations currently under construction or ...

Problems solved by technology

Despite this, the construction of intelligent substations still faces many problems: 1) Although the intelligent substations currently under construction or in operation all conform to the DL / T 860 standard, due to the different technical methods and intelligence levels used in various places, and The degree of intelligence between the completed stations and the stations under construction is also different, so the operation, maintenance and management methods of each station cannot be unified and standardized; 2) The monitoring systems of the equipment in the station are independent of each other, and the data cannot be directly converted, resulting in The difficulty of analyzing massive data is greatly increased; 3) The intelligent substation can only be designed once at the construction stage, and there is little room for improvement in the later stage, and the system's expansion ability is low

However, it can only visually monitor the appearance of the substation, but cannot monitor its operating status well
