The presence of renewable energies on the distribution grid is continuously evolving, influencing more considerably the overall comportment of the power system. The intermittent character of the primal energy (wind, sun, water) increases the complexity of the problem, thus new test facilities must be developed. As power electronics are generally part of these production systems, high frequencies are involved so the test facilities must be well adapted. The present paper proposes the Real-Time (RT) Hybrid Simulator as a very flexible test facility, well suited for the study of grid connected electrical devices.

“…It was also utilized for the type testing of prototype equipment and verification for various customer applications. This facility has upgraded its capability by installing a state-of-the-art realtime digital simulator from Electricity de France (EDF) [4]. P To keep pace with the development of the simulation technology, the facility in the US has also installed a real-time digital simulator from EDF at Allentown, Pennsylvania, in 2001, to replace their third model power system at Coral Springs, Florida.…”

With the introduction of high-speed relaying systems, the need for extensive testing of these systems for different fault and abnormal conditions has become more important, to ensure the security and dependability of the electric power systems. Testing of relays can be summarized into three groups: steady state, dynamic and transient. While the first two types are performed during bench testing, they are not adequate for performance evaluation of sub-cycle modern relays. Transient testing is performed for verification of relay performance under transient conditions of power system to address such requirement. ABB has been using real-time simulations of power systems, for relay performance evaluation, for around seventy years in the US. This paper discusses the methodology employed for real-time simulations of power systems with different technology, with specific focus on the state-of-the-art real-time digital simulator from EDF. Specific case study related to the performance evaluation of a Line Relay System is discussed in this paper.
