Testing methods of power swing blocking functions of distance protection relays

Abstract

The paper describes testing of distance protection relays’ power swing blocking functions (schemes). Basic and extended scopes of tests are proposed for power swing blocking functions. Test systems are proposed, and test modules of microprocessor tester software are described, which can be used for testing power swing blocking functions.
