Model predictive control algorithms have recently gained more importance in the field of wind power generators. One of the important categories of model predictive control methods is improved deadbeat control in which the reverse model of generator is used to calculate the appropriate inputs for the next iteration of controlling process. In this paper, a new improved deadbeat algorithm is proposed...
This work discusses the implementation of an efficient fault-tolerant control in a multiphase wind energy conversion system. The conversion system consists of an asymmetrical six-phase induction generator supplied by four voltage source converters (VSCs) in a hybrid series/parallel configuration Post-fault operation must preserve the current ratings of the system and should also maximize the generated...
Multiphase generators in multi-MW wind energy applications can be realized with a variety of possible topologies. Series connection of machine-side converters elevates the dc-link voltage for the same voltage rating of IGBTs, allowing medium voltage generation on the grid-side. On the other hand, parallel connection of machine-side converters provides fault-tolerant capability, enhancing the system...
As high power applications in industry commonly employ multi-phase motors and generators, a generic solution is needed for fault diagnosis of various multi-phase systems. Furthermore, the fault criteria set for the severity of the detected fault signature has still been a challenge due to the dynamic behavior of the fault-related signatures in the motor line current. Therefore a generalized solution...
