| Abstract |
In this work the modelling and design for a wind generation control system using the doubly-fed induction machine and a DSP-based experimental set-up construction as well as part of its commissioning are presented. A DC-machine driven by a thyristor bridge emulates the windmill and is connected to the shaft of the generator. The latter is fed through its slip-rings by a back-to-back converter consisting of 2 IGBT-VSI connected with a DC-Link. The stator is directly connected to the grid. An LC-Filter at the output of the mains-side inverter supresses the harmonics and furnishes the required reactive power to the system. The system’s electrical losses are minimised through an optimal control strategy in which the reactive powers of both converters are simultaneously controlled. Due to the amount of required variables and measured quantities, as well as, the complexity of the control structure a powerful processing capability is needed. All of these features make a very interesting and challenging engineering task. Some simulation and experimental results will be shown and inherent problems of the commissioning will be addressed. |
