Abstract

The aim of this paper is to analyze the control of several wind power generators with one common power converter. This configuration is especially useful for offshore wind farms with a VSC-HVDC transmission to an onshore system. A comparison with a more conservative topology, where one generator is connected to one power converter, is done focusing in the total power extraction. Scalar-controlled squirrel cage induction generators have been implemented in both cases. The control scheme has been slightly modified implementing an aggregated model in order to allow the common converter to perform the proper control tasks. Results have been validated by means of simulation in both scenarios showing the differences in the total power obtained and the influence of the generator operating point.
