Phasor-Based Monitoring with HVDC Control (NIA funded project)

The HVDC Phasor Based Monitoring project is part of SSEN’s Innovation Program; where SSEN, GE and the HVDC Centre are project partners. This project aims to evaluate the electricity network system strength using the Phasor Point Wide Area Monitoring System (WAMS) to potentially support the stability of the large embedded HVDC links (for example Caithness-Moray located in the north of Scotland).

As part of this project, HIL (Hardware-In-the-Loop) testing of the WAMS along with the physical and simulated PMUs (Phasor Measurement Units) will be undertaken to ensure accurate measurement data collection takes account of the differences across real devices . This project will then demonstrate how wide area PMU data can be used to calculate system strength in real-time platforms in order to inform the ideal HVDC converter operating states as the conditions of the onshore network.
