Embodiment 1

[0028] Such as figure 1 As shown, a method for automatically associating primary and secondary equipment models of a smart substation includes the following steps:

[0029] Step 1. In the ICD (IED Capability Description File) file, for the cross-bay secondary equipment model, configure and set the bay prefix for each bay LN in the model to complete bay LN grouping, and establish bay association LNs to provide a secondary bay association interface. In this way, the bay is associated with the LN in it, and the bay-associated LN interface is provided for the integration of the smart substation through the bay-associated LN;

[0030] Set a specific bay prefix for the function, measurement, input and output of different bays in the secondary equipment model across the bay in the ICD file; for example, the current amplitude of bus protection bay 5 is B5MMXU1, and the trip of bay 7 is B7PTRC1, etc., B5 and B7 is the set interval prefix;

[0031] Interval-associated LN is composed o...

Embodiment 2

[0065] An automatic association device for primary and secondary equipment models of an intelligent substation, comprising:

[0066] The bay associated LN configuration module uses the set interval prefix to distinguish the secondary equipment LN of each bay for the cross-bay secondary equipment model, and establishes the bay associated LN to provide a secondary bay associated interface;

[0067] The assignment module is used to configure the SCD file to complete the instantiation of each secondary device model, import the SSD file into the SCD file, directly associate the single-interval secondary device CID file with the relevant primary interval in the SSD, and link the inter-interval secondary device CID files Each interval DO assignment of the interval association LN to complete the interval association;

[0068] The association module is used to specify the secondary equipment LN association relationship for the primary equipment object type; according to the primary equ...

Abstract

The invention discloses an automatic association method and device for primary and secondary equipment models of an intelligent substation, and the method comprises the steps: configuring a specific interval prefix for each interval LN (logic node) in a cross-interval secondary equipment model, grouping the intervals LN, and building interval association LN, and providing a primary and secondary interval association interface; configuring an SCD file to complete instantiation of each secondary equipment model, importing the SSD file into the SCD file, directly associating a single-interval secondary equipment CID file to a related primary interval in the SSD, and assigning each interval DO of interval association LN in the cross-interval secondary equipment CID file to complete interval association; assigning a secondary equipment LN association relationship for the primary equipment object type; and associating the primary equipment in each interval with the related secondary equipment LN in each single-interval and cross-interval secondary equipment model according to the association relationship between the primary equipment object type and the secondary equipment LN. Accordingto the method, automatic association of primary and secondary equipment models of the intelligent station is realized.

Description

technical field [0001] The invention relates to the technical field of intelligent substations, in particular to a method and device for automatically associating primary and secondary equipment models of intelligent substations. Background technique [0002] The IEC61850 standard is the basis for the construction of smart substations. The standard defines the configuration system specification description SSD (system specification description) file, which describes the primary system structure and the relationship between primary and secondary equipment. Association relationship, which can obtain useful information such as which secondary equipment logical nodes (LN, abbreviation of logical node) are associated with a certain primary equipment, and which secondary equipment logical nodes are associated with the same interval, but take a medium-scale 220kV smart substation as an example , Hundreds of secondary devices need to be associated with thousands of LNs with primary ...
