Implementing substation automation load transfer function

摘要

A process of implementing, or engineering, topology-dependent functions based on a formal description of the Substation Automation system, includes performing a topology analysis of the current single line state. A topology interpreting implementation replacing complex topology analysis logics can include the project specific static single line topology and the connection to the real process state data. All information can be delivered in an IEC 61850 conforming SCD file. The interface description for controlling and monitoring the load transfer application can be generated automatically from the SCD file.

1. A method of implementing a load transfer function in a Substation Automation SA system for a substation supplying electric power to a load, comprising:
reading a standardized configuration description of the SA system, to obtain a static topology representative of at least a part of the substation as well as information about primary elements of the substation; repeatedly updating a dynamic substation topology based on a switch status of a switching device of the substation; for a transformer connecting a first bus bar to a second bus bar of the substation, identifying, based on the dynamic substation topology, primary elements arranged between the first and second bus bar; determining a load transfer function by selecting, based on a status of the identified primary elements, a primary element that has to be activated in order to connect the first to the second bus bar; and storing the load transfer function to be executed in case of a failure of the transformer.
