Introduction: This project has investigated Active Voltage Control (AVC) to increase the efficiency of the network and to facilitate the connection of distributed generation. The project has undertaken field trials of the Fundamentals SuperTAPP n+ (AVC) relay and develop associated modelling criteria for network planners.

Objectives: To investigate the performance of the Fundamentals SuperTAPP n+ AVC relay to regulate voltage on 33kV and 11kV network feeders where both load and generation are present.
