Abstract:
1. A wind turbine generator control system, for a plurality of windfarms each including at least two wind turbine generator connected through a collection bus and main transformer to a point of common connection with a transmission network including a plurality of generator/load groups physically distributed within the transmission network and including at least one non-renewable energy source, comprising: a windfarm controller for each of the plurality of windfarms, wherein the windfarm controller controls operation of the at least one wind turbine generator within the windfarm; at least one measurement point on a transmission network, the at least one measurement point being remote from the point of common connection for each of the plurality of windfarms, for measuring operating parameters of the transmission network; a plurality of sensors on the at least one measurement point on the transmission network, remote from the point of common connection for each of the plurality of windfarms, for measurement of transmission network operating parameters related to control of each of the plurality of windfarms; a coordinated windfarm controller employing at least one of the measured transmission network operating parameters related to control of the at least one windfarm generating output signals for stability of the transmission network at a location remote from the point of common connection of each of the plurality of windfarms with the transmission network; and communication means for transmitting the transmission network operating parameters for a location remote from the point of common connection for each of the plurality of windfarms to the coordinated windfarm controller and transmitting the output signals to at least one of the plurality of windfarms.
