The use of phasor measurement unit (PMU), also known as synchrophasors, for monitoring of electrical powersystem states, stability and health, experiences an increasing growth throughout the world and especially inNorth America. The creation of the North American Synchrophasor Initiative (NASPI), for instance, has drawnthe attention of researchers and utilities worldwide and has helped in increasing the quality of research in thatarea. The Institute of Electrical and Electronics Engineers Standards Association (IEEE-SA) has issuedstandards on the performance requirements of PMUs and the test equipment required to achieve certification.These tests as well as the requirements for the test equipment are known to be very stringent. PMUs need to bevery accurate to ensure the best possible visualization of the grid condition and ensure reliability of the futureadvanced controls.A synergy between Canadian companies, namely Hydro-Quebec's Research institute (IREQ), Vizimax andOPAL-RT Technologies, have led to interesting developments in the area of synchrophasors. OPAL-RT andIREQ signed a strategic collaboration agreement for the shared commercialization and development ofHYPERSIM in 2012. There has also been an agreement between Vizimax and IREQ for the integration ofestimation algorithms resulting from research at IREQ. The algorithms have been enhanced by Vizimax foraccurate real-time estimation and standard compliance and the resulting PMU is commercialized by Vizimax.In 2015 and 2016, OPAL-RT has collaborated with VIZIMAX in order to help them prepare for the officialIEEE certification, by developing the required test rig on their real-time simulation platform HYPERSIM. TheVizimax PMU is now the second one worldwide which has passed the certification program. To OPAL-RT,this consisted in Phase 1 for the development of an integrated test platform and there are multiple other featuresto develop to make sure the platform can be used for official certification.
