GenAVC is installed at the primary substation. Measured parameters from the generator and primary substation are fed into a state estimator. The output of the system biases the target voltage of the traditional substation Automatic Voltage Controller (AVC).
North Norfolk has a number of small wind-farms connected to the EDF Energy Networks’ 11kV rural network. The circuits are mostly overhead feeders of various lengths. Voltage rise is a clearly documented problem that needs to be solved to allow increased penetration of DG to be connected to these networks without the costs of traditional reinforcement methods.

GenAVC has been developed in conjunction with EDF Energy Networks and United Utilities as a solution to this problem. GenAVC has been installed at Martham Primary, North Norfolk.
