The fault-tolerant technique in the Rotor Current Controller in Induction Wind Generator

The thesis expounds the importance of the rotor current controller in induction wind generator in wind generator sets. The topic analyses the kind and the source of the faults of the rotor current controller. Also it design the method of the technology of tolerating faults in the rotor current controller. Some kinds of the technology of tolerating faults are used in hardware and software. So the system can identify the kinds of the fault and eliminate the fault, then making the system can control itself and achieve the best work state again. Using mix redundant methods in software part in order to protect the program running reliably and disposing dates correctly. The system which can be controlled remotely and showed communicates with the computer and can send the result of diagnosis to it in time.
