ABSTRACT:
A windfarm system is provided that is optimized for minimizing electrical loss. The windfarm system includes a plurality of wind turbine generators and a collector system including a conductor or network of conductors. The collector system also including a plurality of transformers with one or more transformers connected between each wind turbine generator and the conductors, and a substation transformer connecting the windfarm collector system to the electrical grid. The windfarm system also includes a monitoring system for monitoring the windfarm system electrical output and thermal condition, and outputs of the individual wind turbine generators. A control function may include voltage and real and reactive power commands to the individual wind turbine generators. The control function incorporates an algorithm whose technical effect is minimizing electrical losses for the windfarm system.
