Robustness investigation of Vector Control of Five-phase PMSG based Variable-Speed Wind Turbine under faulty condition

摘要

Wind energy becomes recognized as a resource for sustainable electrical power generation. However, the main challenge for this kind of energy development is to minimize the operation costs and maintenance operations in the wind harsh environment. These worries are justified by the incident high rates on offshore wind turbine systems. Wind energy turbines are characterized by a very difficult access for regular or emergency maintenance operations. This is why the development of fault tolerant system is a key feature. This paper deals with the use of a PM five phase wind turbine generator. With this kind of system, it is possible to maintain the power production even if an electrical fault appears in the power converter. This system is associated with an optimal strategy of torque/speed control using a vector control. This approach is evaluated in this study in the healthy and faulty operation modes.
