Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] figure 1 The flow chart of the bus conversion method for the source end maintenance of the power system of the present invention includes:

[0027] S101: Extend the connection point object in the substation description system based on the IEC 61850 standard, and add type description parameters for the connection point object;

[0028] S102: The scheduling master identifies the type description parameter of the connection point object, and creates a bus device when the type description parameter is determined to be a bus.

[0029] For the system at the dispatching master station end, if there is no description of the busbar equipment, the node branch model will not be formed, and the calculation of high-level applications will not be possible. Therefore, th...

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...
