Problems solved by technology

Since the SCD file is different from the CIM / E and CIM / G files in the grammatical structure of the file, the emphases of the modeling, and the representation method of the model relationship, the smart substation and the dispatching master station maintain their own files and graphic model information, it is difficult to share information

Embodiment 1

[0047] In step three, the conversion steps are as follows figure 2 as shown, figure 2 A schematic diagram of the method, including the following steps:

[0048] Step 3a performs syntax and functional verification on the SCD file;

[0049] Step 3b According to the mapping relationship between SCD file and CIM / E, CIM / G file and database in primary equipment, secondary equipment, primary equipment topology, primary and secondary equipment association and image description, establish model conversion rule file and Graphical conversion rule files, model conversion rule files and graphic conversion rule files convert the complex correspondence between SCD files and CIM / E and CIM / G files into one-to-one simple mapping relationships;

[0050] Step 3c extracts the verified SCD file, extracts the model information and graphic information, marks the relationship between the model time, and fills in the identification mRID of the model information and the identification keyID of the g...

[0054] In step 3a, the conversion of the model is involved, and the method is as follows:

[0055] For an equipment model conversion, according to the difference between the description of the equipment model in the SCD file and the CIM / E file, it is divided into the following four cases: 1) For the same type, the same name or similar in the SCD file and the CIM / E file , and there is a one-to-one correspondence model, direct mapping; 2) For an SCD model, when there are multiple CIM / E models of the same type, further combine the attributes or descriptions of the SCD model to determine the mapping to a certain CIM / E model; 3) For a model that lacks a definition in the SCD file but exists in the CIM / E file, perform type expansion in the SCD file; 4) For a model that is defined in the SCD file but not in the CIM / E file The model is mapped by means of equivalent treatment in the CIM / E file.

[0056] Secondary equipment model conversion, mainly mapping the analog quantity model an...

Abstract

The invention discloses a method for graph-model information sharing of an intelligent substation and a dispatching master station.The method comprises the following steps that 1, an SCD file containing graphs and model information is created; 2, the dispatching master station guides the SCD file into a regulator control system and verifies the SCD file; 3, the verified SCD file is converted into a CIM / E file and a CIM / G file; 4, the converted CIM / E file is used for completing guiding of a model file through the model splitting and splicing technology; 5, the converted CIM / G file is guided into a man-machine system, graph-model relevance is verified, display is performed, and guiding of a graph file is completed.The static model file interaction process of the intelligent substation and the dispatching master station is simplified, graph, model and library integration of the intelligent power grid dispatching control system is achieved, and the feasible technological means is provided for intelligent power grid source end maintenance and global sharing.

Description

technical field [0001] The invention belongs to the field of electric power system automation, and in particular relates to a method for sharing graphic model information between an intelligent substation and a dispatching master station. Background technique [0002] At present, the smart substation follows the IEC61850 standard, and the substation configuration description file (SCD) defined in it is used to describe the configuration information of the whole substation. IEC61850 is an international standard for power system automation information exchange system formulated by the International Electrotechnical Commission. The SCD file follows the XMLSchema (Extensible Markup Language Architecture) syntax and is used to describe various objects involved in substation configuration, including system structure, intelligent electronic device IED model, communication system model, and instantiated logical node model. [0003] The smart grid dispatching control system of the d...
