Technical Report
10 Jul 2020
Out-of-Step (OOS) protection schemes for generators have received much attention after the 1965 Northeast Power failure and other subsequent power system disturbances. In 1970s, the Rotating Machinery Subcommittee formed a working group that prepared a report on the need for and the methods of accomplishing generator OOS protection. OOS protection has attracted further attention since the 2003 Blackout. In 2010, North American Electric Reliability Corporation (NERC) System Protection and Control Subcommittee produced a Technical Reference Document “Power Plant and Transmission System Protection Coordination” which provides guidance on setting the OOS relay.[1] The assignment of this working group is to produce a report and summary paper explaining the various schemes and setting guidelines in use for OOS protection for AC synchronous generators.
