Method for automatically generating secondary equipment associating configuration based on system description

Abstract

The invention provides a method for automatically generating secondary equipment associating configuration based on system description. The method is characterized in that on the premise that the description of a transformer substation description file on the configuration of a primary system of a transformer substation and related key logic contacts is complete and accurate, a secondary equipment standard information and knowledge library is constructed according to relative standard of relay protection standard design, and the key information is gained from the system description file through the traversal algorithm, and thus the secondary equipment associating configuration of a smart transformer substation can be obtained based on the key information and the standard information and knowledge library. According to the method a standard IEC 61850 model and the system description are utilized to determine the relation of physical devices; the advantages of the standard model are fully utilized, so that the workload of system configuration can be decreased; the communication connection configuration of secondary equipment can be automatically created; a traditional secondary equipment associating manner using one-to-one corresponded positive terminals is completely changed.

Description

technical field [0001] The invention relates to a method for automatically generating associated configuration of secondary equipment based on system description. Background technique [0002] The IEC 61850 standard, as an important standard for smart substations, has been researched and applied on a large scale in my country. In order not to change the design mode of the traditional substation as far as possible and reduce the application difficulty of the smart substation, the design mode of "virtual terminal" is currently adopted in China, that is, the output and input of the relevant IED (Intelligent Electronic Device) are matched in the configuration. The concept of virtual traditional terminals; compared with traditional substations, this method does not reflect the advantages of smart substations. In actual engineering, it is still necessary to manually configure all "virtual terminals", which is a huge workload and prone to errors; IEC 61850 standard The advantage...

Problems solved by technology

[0004] In the second edition of the IEC 61850 standard, in addition to retaining the engineering configuration definition based on the SCL language in Part 6 of the first edition, two configurable data objects, InRef and BlkRef, are added to the logical node to perform "online" association of input signals; however, The source, internal address and destination of the device can be set separately, which is more cumbersome and complicated than the method of using "virtual terminals"; in addition, the automatic association of related information sorting from the communication level through the two setting values ​​of InRet' and BlkRet' requires complex It can be realized by GetGoReference or Get—GOOSEElemetNumber communication service, which is currently not supported by almost all manufacturers, and will also bring the complexity of GOOSE (Generic Object-Oriented Substation Event) communication association and reduce communication reliability; in addition, the standard There is no related service that defines SV (sample value), and it is impossible for SV input to achieve signal correlation in this way; therefore, this scheme cannot be applied in our country
