Intelligent substation virtual terminal automatic association method based on standard function coding

Abstract

The present invention relates to an intelligent substation virtual terminal association method, in particular to an intelligent terminal substation virtual terminal automatic association method basedon the standard function coding. The method comprises the following steps that: 1) an ICD file function coding template library is established, and function coding is carried out on the device virtualterminal; 2) a standard virtual terminal template library is established; 3) the ICD file in the project is corresponded to the function coding template library to implement automatic coding; and 4)the automatically encoded virtual terminal carries out automatic association according to the standard virtual terminal template library, and the required SCD file output application is finally formed. The method disclosed by the present invention has the advantages that: the virtual terminal marking method taking the secondary system function loop as the core can effectively avoid the problem that the definitions of the virtual terminals in various domestic manufacturers are difficult to be unified, and the function coding shields the difference between virtual terminals of different manufacturers, so that the match rate of the automatic coding and the success rate of the automatic association can be significantly enhanced.

Description

technical field [0001] The invention relates to a method for associating virtual terminals of an intelligent substation, in particular to a method for automatically associating virtual terminals of an intelligent substation based on standard function coding. Background technique [0002] At present, the main ideas of the research on the automatic association of virtual terminals can be divided into two categories: matching by characters or matching by solidifying the sequence of virtual terminals. These methods all have some things in common, for example, need to standardize technology based on ICD files, and need to establish a standard template library etc., with the support of these standardized data for automatic matching or solidified matching; this may cause the following problems in practical engineering applications: [0003] (1) Too much reliance on the standardization of the original data may affect the automatic matching rate of virtual terminals. This is because...

[0003] (1) Too much reliance on the standardization of the original data may affect the automatic matching rate of virtual terminals

This is because although the State Grid Corporation of China has issued relevant smart substation model file specifications, there are many secondary manufacturers in China, and the model file differentiation among different manufacturers is inevitable, so there will be some differences in the corresponding standardized data. As a result, the automatic matching rate of virtual terminals between devices from different manufacturers is reduced, and the practical effect is poor.

[0004] (2) Relevant standardized specifications should be applicable to all devices, so it is difficult for the construction rules of the template library to be detailed or scientific and reasonable, and the correctness of the template library directly affects the effect of automatic association
