Piloting Wireless Communication-based Condition Monitoring in an HVDC Station

High-voltage direct current (HVDC) systems are representing one of the backbone of modern power systems. As the fleet of installations grows all over the planet, TSOs and manufacturers are putting advanced condition monitoring systems into place which are usually based on data from permanently installed, wired sensors. If additional sensors are required in existing brownfield HVDC stations, wired sensors are often too costly and complex to install in the planned and optimized maintenance windows. On the other hand, temporary installations of specific sensor systems are often sufficient to detect abnormalities or conduct root cause analysis during trial, warranty or end of life periods. Wireless sensor networks (WSNs) based on low cost, low energy battery-powered wireless sensors are well…
