| Abstract |
Wind energy conversion is a fast growing technology with expanding possibilities of application. The
usual problems are the stringent control specifications due to variable speed operation and the need for
optimal wind speed tracking for improved efficiency. These have made the use of doubly-fed
induction generators very attractive. In this paper therefore, a wind powered DFIG which feeds a DC
load is investigated. It is shown that the inherent high control flexibility of the system results in
optimised power flow. Electrical losses can then be minimised and system efficiency improved.
Simulation studies of a prototype wind powered generator system employing a thyristor-bridge
controlled DC motor, which simulates a wind turbine, as prime mover, will be presented. |
