Bus conversion method and device for maintaining source end of power system

Abstract

The invention discloses a bus conversion method and a bus conversion device for maintaining the source end of a power system; the method comprises the following steps that a connecting point object in a transformer substation description system based on an IEC 61850 standard is expanded, and a type description parameter is added for the connecting point object; a scheduling main station end identifies the type description parameter of the connecting point object; and when the type description parameter is judged to be a bus, bus equipment is created. After the invention is adopted, the connecting point object can be expanded based on the IEC 61850 standard, the bus can be identified on the premise that no bus interval and other external new concepts are introduced, so that the sharing and the maintenance of bus information which is converted from an intelligent transformer substation to a main station are realized conveniently.

Description

technical field [0001] The invention relates to the technical field of power system source end maintenance, in particular to a bus conversion method and device for power system source end maintenance. Background technique [0002] At present, the smart grid is the research focus and development trend of my country's power grid technology, which has risen to the height of the national strategy, and the smart substation is an important part of this strategy. The key to intelligent substations is to realize the unified modeling of the whole station data, and realize the unified description of the properties, capabilities and behaviors of secondary devices and primary equipment in the station, so as to make information sharing and interoperability between different intelligent electrical equipment possible. Realize the intelligent substation in the true sense. As a result, the new technical field of source-end maintenance of power systems has emerged. [0003] The "Technical G...

AI Technical Summary

Problems solved by technology

However, due to the lack of description in the IEC 61850 standard itself, the busbar cannot be identified during the conversion of the smart substation model based on the 61850 standard

The current status of the above-mentioned engineering applications urgently needs to explore a set of technical solutions to realize data source maintenance at the substation end and data sharing at the dispatching station end, otherwise it will affect and restrict the development of smart substation technology
