In the three setups mentioned above, the tests to be carried out were agreed HYPERSIM® network interfaced with the “Old replica” upon by the Stakeholders. The IREQ HYPERSIM® network interfaced to New Nicolet and the test program was intended to follow rest of the existing replica : Mix-Mode the different steps on site HYPERSIM® network with the “All” New replica > Test Program in accordance with the steps of the project • • Phase II : CPT , FST (local sequences) & some selected protection tests in Mix. Mode • Phase III : CPT, FST (local and master sequences, local and master power and voltage control) & protection tests with the new replica. Various contingencies in synchronous, islanded, bipolar monopolar or hybrid modes • 17 Phase I : CPT with the original(Old) replica for reference tests.

Main benefits of Using Replica of CPS Interfaced to Real -time Digital Simulators > Reduce the commissioning time and cost > Increase the reliability of the equipment operating in the power grid > Contribute to the reliability and the safety of the power system under normal and abnormal operating conditions. > Follow the evolution of the power grid for the lifetime duration of the equipment > Support the power exports between HQ and the neighbouring networks > Better understand the interactions between different equipment in the power grid. > Take advantage of IREQ lab for training purposes (engineers and operators) 25 HQ experiences in case of using control system replica interfaced with Hypersim real-time simulator in recent HVDC projects

Conclusion Presentation focusing on : • • Flexible interface developed to allow easy switching between « Original » and « New » replicas • Validating mix-mode configuration: New Nicolet with the original remaining replica • Running of multiple configurations with various contingencies according to the accepted test program to validate functions and systems • Validation of the test procedures for the two commissioning phases • 26 Hypersim description as a real-time simulator capable of interfacing with external replicas of HVDC/FACTS systems New CPS simulation results compared favorably with the original replica and the on-site commissioning tests HQ experiences in case of using control system replica interfaced with Hypersim real-time simulator in recent HVDC projects
