Transformer substation online secondary equipment standing book information acquisition method

Abstract

The invention discloses a transformer substation online secondary equipment standing book information acquisition method. According to the invention, content extension is carried out on an IEC61850 model of equipment such as a protection device, a measurement and control device and the like in the substation, and secondary equipment standing book information is written into a CID model and transmitted to a background monitoring system. The background monitoring system is upgraded, and the acquired secondary equipment standing book information is compiled into a monitoring system model through substation control level MMS communication. Through the technical scheme disclosed by the invention, the monitoring system can update transformer substation secondary equipment information in real time, all-station model integration is carried out on acquired single device information so as to generate a whole plant station secondary equipment model, the acquired information is provided for a power grid information system to use so as to realize overhauling assistance, operating assistance and asset life cycle management of a transformer substation, a panoramic model of the transformer substation and the equipment is constructed, and the informatization, automation and intelligentization level of the transformer substation can be improved.

Description

technical field [0001] The invention relates to a method for realizing real-time collection of secondary equipment ledger information in a substation by cooperating with a relay protection device, a measurement and control device, and a monitoring system, in particular to a substation online secondary equipment ledger information collection method. Background technique [0002] The secondary equipment ledger information mainly includes: interval name, installation location, voltage level, manufacturer, equipment model, date of manufacture, date of commissioning, device power supply type, primary rated voltage, secondary rated voltage, primary rated current, secondary Rated current, program version, program date, verification code, plug-in information, etc. Information comes from design drawings, product manuals, and secondary equipment itself. [0003] At present, the information database of the primary and secondary equipment in the substation is established by means of ca...

Problems solved by technology

The correctness and comprehensiveness of the information collection content of this kind of equipment are greatly affected by human factors, and it is easy to cause the situation that the database information does not match the actual information of the device.

At the same time, the equipment information in the substation is constantly updated and changed due to technological transformation, product upgrades, etc., resulting in a huge workload for manual collection.

[0004] The equipment information of some existing manufacturers’ devices can be uploaded to the dispatching master station through the protection information substation system or the telecontrol system through the device description or fixed value. The real-time performance meets the requirements, but there are still the following limitations: 1) Only small...
