Description

METHOD AND APPARATUS FOR AUTOMATICALLY ASSOCIATING PRIMARY DEVICE MODELS WITH SECONDARY DEVICE MODELS OF SMART SUBSTATION

TECHNICAL FIELD

The present disclosure relates to the technical field of smart substations, and in particular, to a method and apparatus for automatically associating primary device models with secondary device models of a smart substation.

BACKGROUND

lEC 61850 is the basis for construction of smart substations, which defines a configuration system specification description (SSD) file. The file describes a primary system structure and a primary device association relationship and a secondary device association relationship, which is actually a link file. Useful information such as one primary device associated with which secondary device logical node (LN) and which secondary device LNs associated with a same bay may be obtained through the primary device association relationship and the secondary device association relationship. However, taking a medium-scale 220 kV smart substation as an example, hundreds of secondary devices are required to be associated with thousands of primary device LNs, which objectively brings a lot of obstacles to application of the SSD file. Currently, during integration process of the smart substations, the primary device LNs in the SSD file are basically not associated with the secondary device LNs, and the SSD file is not configured for many substations.

In recent years, advanced application technologies for operation and maintenance of the smart substations continue to develop. Functions based on secondary device information include same-origin comparison analysis of analog quantities and switch quantities originating from same primary devices, and monitoring of corresponding states of primary devices and secondary devices. Due to an unclear relationship between the primary device and the secondary device, the data foundation of the advanced application based on the states of the primary devices and the secondary devices and state information between the secondary devices in a bay is very poor. All configuration processes directly face instantiated specific apparatus models, and single-bay configuration achievements cannot be reused at all. Signals are required to be configured for each bay and each application function one by one, configuration efficiency is extremely low, and configuration correctness is difficult to guarantee Once a model of a device is changed, the related configuration needs to be performed again.

Based on the above, it is urgent to study how to automatically associate primary device models with secondary device models of the smart substation, so as to promote the practical level of the smart substation based on an advanced function with respect to smart application of information of the primary devices and the secondary devices.

Step 1: In an ICD (the IED Capability Description) file, for a cross-bay secondary device model, assign corresponding bay prefixes to bay logical nodes (LN) in the model to group the bay LNs, and establish a bay association LN to provide an interface to associate a primary bay with a secondary bay. In this way, a bay is associated with an LN in the bay, and an interface for associating the bay association LNs is provided for integration of the smart substation through the bay association LN.

Corresponding bay prefixes are assigned to LNs, which are responsible for functions, measurements, inputting/outputting, and the like of different bays in the cross-bay secondary device models in the ICD file. For example, a current amplitude of a busbar protection bay 5 is B5M1VDCU1, tripping of a bay 7 is B7PTRC1, and like, B5 and B7 are set bay prefixes.

The bay association LN is composed of bay name DOs (data objects). For example, a structure of a certain bay association LN is defined as shown in Table I. DO is the data object, and an LN is usually composed of a plurality of DOs. For example, the busbar protection can protect buses with 10 bays, and an interface is required to be provided to associate 10 bays In this method, a bay association LN is specially set for this purpose, and the bay association LN is composed of DOs corresponding to the 10 bays.
