Adding Flexibility to Protection and Control Systems
By Jared Mraz and Keith Gray
IEC 61850 GOOSE messaging provides an incredible amount of flexibility to the design and implementation of protection and control systems. This flexibility was essential to recent projects involving the upgrade of the electrical distribution system at an oil refinery. GOOSE was used for transfer tripping, breaker failure, islanding detection, remote synchronizing, automatic restoration, manual transfer, and load shedding.
This paper describes the design approach for each scheme, documentation methods, and lessons learned. Data from live event captures is included to demonstrate the operating speed of the schemes.
