Resumo: | In recent years, with the development of micro and power electronics, the switched reluctance machine has been gaining popularity. This type of machine is attractive because it has a cheap and easy construction, having absence of rotor windings and permanent magnets. It has also an inherent fault tolerance ability. Due to this fault tolerance it has gained the attention of industries and applications that require safe and reliable operation. However, the machine is only fault tolerant to a point and, with the aim of improving its already high fault tolerance, multiple studies were conducted on the subject. In this dissertation a new passive fault tolerant method, comprising on simple modifications in the windings, converter and control method will be presented. Worth notice that one of the modifications is already discussed in the cited literature. This method is aimed principally at open circuit faults in the windings with the machine working as a motor in the low speed zone. The effectiveness of this method will be studied by comparison of a regular SRM with one with the solution through simulation of winding fault conditions, namely open and short circuits faults. In order to do this, first finite element analysis was performed, with the software Flux2D®, in order to obtain the magnetic and torque characteristics of the machines. This was followed by dynamic simulations in Matlab-simulink®. It will be shown that the method is very effective for open circuit faults but will only have negligible improvements in case of winding short circuits. |
