LV & 11kV Networks
GenAVC has been developed by Econnect Ventures Ltd to manage voltage rise issues associated with the connection of Distributed Generation (DG) into 11kV networks. This system had achieved satisfactory operation in a trial at Martham Primary substation. The trial demonstrated that principles of voltage control could be applied in order to reduce the target busbar voltage and minimise network constraints.

At Horton Quarry, a landfill gas generator experiences nuisance trips during times of low demand. This project proposed to produce a generic tool to assess the benefits of the GenAVC solution. A comparison of the output of this assessment tool, with traditional methods of solving voltage rise issues, was carried out.

A generic assessment tool to assess the benefits of the GenAVC solution.

The tool showed that GenAVC was a solution, and a commercial grade GenAVC was installed at Steyning primary:

  • To validate the management of the voltage rise issues

  • Avoid the occasional disconnections of the generator

  • Demonstrate that GenAVC provides the least cost connection for DG when additional generation capacity is sought.
