PROJECT TITLE :
Open-Circuit Fault-Tolerant Control for OuterSwitches of Three-Level Rectifiers in WindTurbine Systems - 2016
A 3-level converter is used as the ability converters of wind turbine systems because of their benefits such as low-current total harmonic distortion, high efficiency, and low collector-emitter voltage. Interior permanent magnet synchronous generators (IPMSGs) are chosen as the generator in wind turbine systems as a result of their advantages of size and potency. In wind turbine systems consisting of the 3-level converter and the IPMSG, fault-tolerant controls for an open-circuit fault of switches ought to be implemented to improve reliability. This paper focuses on the open-circuit fault of outer switches (Sx1 and Sx4) in 3-level rectifiers (both neutral-point clamped and T-sort) that are connected to the IPMSG. Yet, the results of Sx1 and Sx4 open-circuit faults are analyzed, and based mostly on this analysis, a tolerant control is proposed. The proposed tolerant management maintains traditional operation with sinusoidal currents underneath the open-circuit fault of outer switches by adding a compensation value to the reference voltages. The effectiveness and performance of the proposed tolerant management are verified by simulation and experiment.
