Abstract
A wind turbine generator control system is provided for controlling output of a plurality of tightly-coupled windfarms connected at a point of common coupling with a power system grid. A master reactive control device employs algorithms whose technical effect is to coordinate the real power, reactive power and voltage output of the multiple windfarms. The controller incorporates a reactive power regulator that can be used to regulate reactive power, power factor or voltage at the point of common coupling and an active power regulator that can be used to regulate real power at the point of common coupling; such that each windfarm is not asked to contribute or violate its own operating capability.
