An Advanced Real Time Digital Simulator Based Test System for Protection Relays

This paper reports on the developments of the real time digital simulator (RTDS) based test systems for protection relays. The background of the developments in protection relays and their associated technologies, such as optical transducers and IEC 61850, are introduced. New developments in RTDS systems are described. It is shown that the current development in transducers and communication technology will have great impact on the developments of protection relays and their associated RTDS based relay test systems. The paper further describes the current, new developments and the future trend in the development of protection relays and their associated RTDS systems
