Demonstration of Multi-vendor Protection Systems for Multiterminal VSC-HVDC Networks

This paper outlines the demonstration of partially selective and fully selective HVDC protection systems using a simulated industrial case study HVDC network, hardware HVDC protection IED prototypes, and simulated HVDC circuit breaker models. A summary of results are presented demonstrating the performance if the protection IEDs and indicating successful operation of the overall HVDC protection system according to system-level indicators. The presented results are intended to increase confidence that HVDC protection systems for multi-vendor HVDC networks are near ready for full-scale industrial implementation.
