Automatic association method of virtual terminals in smart substation based on standard function coding

Abstract

The present invention relates to a method for associating virtual terminals in smart substations, in particular to a method for automatically associating virtual terminals in smart substations based on standard function coding. Functional coding of virtual terminals, 2) Establish a standard virtual terminal associated template library; 3) Correspond the ICD file in the project to the functional coding template library to realize automatic coding; 4) The virtual terminal after automatic coding is based on the standard virtual terminal associated template library Perform automatic association, and finally form the required SCD file output application. The advantages of the present invention are: the virtual terminal marking method centered on the secondary system functional circuit effectively avoids the problem that the definition of virtual terminals of various domestic manufacturers is difficult to unify, and the functional coding shields the differences between virtual terminals of different manufacturers, which significantly improves automatic coding Match rate and success rate of auto-association.

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
