High-frequency disturbances from power converters on system operation call for high fidelity measurements. Synchronized waveform monitoring (SWM) is an emerging technology that extends the scope of synchrophasor technologies by providing wider bandwidth measurements including harmonics and electromagnetic transients across wide geographical areas.

Today with the help from 5G wireless and fibre optics, it is possible to acquire waveform measurements from the meters in real time. The technology has great potential, however, the application is in its infancy. The ESR will develop a real time data analytic workflow for offshore wind and O&G platforms, and through historical and formulated disturbance patterns, the algorithm will detect disturbances and identify the root cause. Both field and simulated measurements will be exploited through real time data platform and stream data analytics. Applications will be developed for monitoring and protection of weak AC systems and O&G platforms.
