IEC 61850 GOOSE messages
This paper describes the implementation of a circulating current scheme that uses IEC 61850 GOOSE messages to provide automatic voltage regulation for up to four paralleled power transformers.
IEC 61850 need not be applied on a substation-wide basis. There are many power system operation and control challenges that can be solved using parts of the technology outlined in the standard.
The paper is a tutorial for junior or graduate engineers to de-mystify the circulating current principle and encourage the use of IEC 61850 and relay logic to solve power system control and protection issues.
Hardware selection, scheme design, and network considerations are explored. The paper discusses lessons learned from setting and commissioning in-service solutions.
This paper presents a control solution that uses IEC 61850 Generic Object-Oriented Substation Event (GOOSE) messages to create an automatic voltage regulator (AVR) scheme that employs circulating current principles.
The paper describes the background of IEC 61850 and some of the solutions GOOSE messaging has enabled. It also explores the requirements for operating transformers in parallel and the need for an adequate control regime.
Finally, the paper shares commissioning requirements and lessons learned from in-service schemes.
The IEC 61850 standard was first released in the latter part of the 1990s. It was adapted from earlier work by the Electric Power Research Institute (EPRI) and the Institute of Electrical and Electronics Engineers (IEEE) that defined the Utility Communications Architecture (UCA).
The IEC 61850 standard consists of a set of documents that describe the substation design, configuration, and testing for both client-server and peer-to-peer communications.
The standard defines five types of communications services. GOOSE messaging is one of the services defined by the standard and may be the most widely adopted part of the IEC 61850 protocol.
