Construction method of full information model for substation and control center graph-model integration

Abstract

The invention belongs to the technical field of power systems, and specifically belongs to a substation and control center graph-model integrated full information model. The invention discloses a novel substation full information model organization scheme; a new model comprises SCD model information and CIM model information; through information extraction and format change, an SCD file and a CIM / E file can be generated; and the substation graph files and the model information are organically combined, so that the graph-model integration of the substation configuration vector graphs is realized, the maintainability of the substation models is enhanced, the workload of the control centers is decreased and the construction of smart power grids is promoted.

Description

technical field [0001] The invention belongs to the technical field of electric power systems, in particular to a method for constructing a full information model integrating a graph model of a substation and a control center. Background technique [0002] When describing the substation model in the power system, there are mainly the IEC61850 standard and the IEC61970 standard. The main station energy management system of the dispatch center follows the IEC61970 standard, and uses the Common Information Model (CIM) to describe the substation configuration, while the substation side follows the IEC61850 standard. Substation Configuration Language (SCL) model to describe. Because the IEC61970 standard of the main station and the IEC61850 standard of the substation only consider their own needs, and define the model of the relevant power system information, which leads to many problems in the construction of intelligent substations and intelligent dispatching management. These ...

Problems solved by technology

[0007] (3) Model update lag

[0008] The model is not updated in time, and the newly put into operation plant and individual operating plants only have measurement models, and no corresponding network models have been established;

[0009] (4) Duplication of modeling work

[0010] When building a new substation, the substation automation system modeling needs to be carried out according to the IEC61850 standard on the substation side, and repeated modeling work needs to be carried out according to the IEC61970 standard on the dispatching center side, and the model information of the same object cannot be shared;

[0011] (5) Communication is complex and information integrity is poor

Since the current IEC61970 is quite mature and widely used around the world, if the CIM model is modified, it will face a global upgrade of the energy management system of the control center, and the implementation of the scheme will cost a lot

The second solution is to establish a mapping between the two models. Since the two models are quite different in terms of description methods, emphases, and description objects, the model information cannot be completely corresponding, and it is difficult to implement one-to-one mapping.
