Addressing emerging network management needs with enhanced WAMS in the GB VISOR project

This paper describes a number of novel Wide-Area Monitoring System (WAMS) capabilities and analysis tools, including a new monitoring solution that covers the 4-46Hz sub-synchronous oscillation range, and the deployment of a new oscillation source location algorithm. These are being demonstrated under VISOR - an innovation project that has created the first integrated GB WAMS in order to demonstrate the capabilities and tangible business benefits of WAMS to the GB system. Other work from the project is discussed including hybrid state estimation, dynamic model validation, line parameter estimation and a new boundary constraint approach that uses angle difference in addition to power. Finally, selected learning from a review of existing GB WAMS performance is presented, along with details of next steps in the project.
