Common Ancillary Protective and Control Functions

The IEEE Power System Relaying Committee (PSRC), Substation Protection Subcommittee, Working Group K5 on Ancillary Protective and Control Functions Common to Multiple Protective Relays have produced a document that addresses the considerations in applying the ancillary protection, control and monitoring functions that are common in multiple relays and the integration of these functions into the overall protection system. Today's modern protection schemes come with fully integrated protection, control and monitoring functions to accommodate the implementation of the different design requirements to achieve a reliable protection and control solution.
