Over the past few years, there has been increased interest in testing
practices for protective
relaying systems. For example, NERC (North American Electric
Reliability Corporation)
produced Standard PRC-017-0 – Special Protection System
Maintenance and Testing, which
states its purpose: “To ensure that all Special Protection Systems (SPS)
are properly designed,
meet performance requirements, and are coordinated with other
protection systems. To ensure
that maintenance and testing programs are developed and
misoperations are analyzed and
corrected”
Moreover, utilities are being asked to document and show
implementation of their maintenance
program.
As a way of supporting this effort, SEL was asked to provide guidance to
the power industry to
address these concerns. The purpose of this paper is to provide
recommendations for testing SEL
relays and guidance for developing a test program. Utilities and other
end users should use their
own experience and expertise to develop and implement their test plans.
