| Abstract |
In this paper, an analysis of different control designs is presented for a variable speed wind turbine (VSWT). Simulation studies are compared with experimental results in a laboratory system.
An experimental rig is used, composed by a DC machine coupled with a wound rotor machine of 15KW. The DC machine with its control actuates as the wind turbine, and the doubly fed machine actuates as the generator.
The study is focused in the control strategy for the emulation VSWT in terms of power quality, reduction of fatigue loads and optimal power generation.
The analysis of the whole system (from wind to electric grid), allows understanding the phenomena that origin power quality, fatigue load and energetic yield problems. Once the causes are detected, improved control algorithms are proposed to optimize the behavior of the wind turbine. |
