Patent ID: 7839024

Claim:
A wind turbine generator control system, adapted for controlling output of a plurality of tightly-coupled local windfarms connected at a point of common coupling and tied to a power grid wherein each local windfarm includes a plurality of wind turbine generators, comprising: a local windfarm controller for each of the plurality of local windfarms, wherein the local windfarm controller controls operation of the plurality of wind turbine generators within the local windfarm, including control for the generation of real power and reactive power for an individual generator of the plurality of wind turbine generators within the voltage and thermal limits of the individual wind turbine generator; sensing means for determining a plurality of power-related parameters at a point of common coupling for the plurality of tightly-coupled windfarms; receiving means for receiving a plurality of power-related parameters from the output of the individual local windfarms; receiving means for receiving a plurality of power-related reference commands from a central system controller for the electric power grid; and a master reactive intra-area controller employing at least one of the plurality of sensed power-related parameters adapted for generating a plurality of power-related commands to each individual local windfarm controller for the plurality of tightly-coupled local windfarms.
