“…Depending on the generator type, there are three classes of WTs with fully rated converters in the wind power industry: WTs with PMSG [2], WTs with wound rotor synchronous generator [3] and WTs with squirrel cage induction generator (SCIG) [4]. WTs with PMSG due to lower maintenance cost, simple structure, enhanced power factor and better maximum power capability are largely used in wind power systems [5][6][7][8][9]. WTs with PMSG are linked to the electric network through back-to-back…”

Wind turbines (WTs) with Permanent magnet synchronous generator (PMSG) are mostly integrated in power systems as popular energy conversion systems. From the machine-side converter (MSC) structure point of view, there are two types of PMSG-WTs: PMSG-WT with voltage source converter (VSC) as the MSC, and PMSG-WT with boost converter-diode rectifier as the MSC. The focus in this paper is on the control modification and dynamic and transient behavior improvement of PMSG-WTs with boost converter-diode rectifier. In this way, inner control loop of the boost converter current and outer control loop of generator speed are developed and extracted. Next, the boost converter control loop is modified by adding two auxiliary control signals, known as auxiliary damping signal and auxiliary compensation signal. The auxiliary damping signal modifies the boost converter current and provides a damping torque for inhibition of WT torsional oscillations. On the other hand, the auxiliary compensation signal, as the second auxiliary signal, limits the dc-link overvoltage during the voltage dip and amends the WT low voltage ride through capability. By modifying the wind turbine control through second auxiliary signal, the size, cost and rated energy of the required dc chopper resistance decrease considerably.

“…The shaft torque T m is proportionally related to the turbine Energies 2017, 10, 706 12 of 24 torque T t . Based on (22) and (30), the value of T e has to change with the wind speed fluctuation to keep the rotor speed steady.…”

“…In [18][19][20][21], the researchers focused on the applications of FSTP topologies in brushless DC (BLDC) [18,21] and DC motors [19,20], however, the machines mentioned above are not usually applied in wind energy conversion systems. One of the commonly used generators in the wind industry is the permanent magnet synchronous generator (PMSG), and in [22][23][24] the authors studied PMSG drives in FSTP converters for WT applications, and fault tolerance was considered. However, the heavy weight and high cost of a PMSG are the main obstacles for its development in wind energy industries.…”

This paper investigates the performance of a fault-tolerant four-switch three-phase (FSTP) grid-side converter (GSC) in a doubly-fed induction generator-based wind turbine (DFIG-WT). The space vector pulse width modulation (SVPWM) technique is simplified and unified duty ratios are used for controlling the FSTP GSC. Steady DC-bus voltage, sinusoidal three-phase grid currents and unity power factor are obtained. In addition, the balance of capacitor voltages is accomplished based on the analysis of current flows at the midpoint of DC bus in different operational modes. Besides, external disturbances such as fluctuating wind speed and grid voltage sag are considered to test its fault-tolerant ability. Furthermore, the effects of fluctuating wind speed on the performance of DFIG-WT system are explained according to an approximate expression of the turbine torque. The performance of the proposed FSTP GSC is simulated in Matlab/Simulink 2016a based on a detailed 1.5 MW DFIG-WT Simulink model. Experiments are carried out on a 2 kW platform by using a discrete signal processor (DSP) TMS320F28335 controller to validate the reliability of DFIG-WT for the cases with step change of the stator active power and grid voltage sag, respectively.

“…When the motor operates under a winding short-circuit fault condition, a great short-circuit current will be generated. The short-circuit current will influence normal phase windings and lead to the system unable to operate normally [4,5,[13][14][15][16]. In addition, the SR motors suffer from drawbacks of larger torque ripple, lower power density, lower efficiency, and bigger noise than permanent magnet (PM) motors [11,12,17].…”

To adapt to the single power supply system of the aircraft, this study proposes and investigates a novel fault-tolerant drive system based on the redundancy bridge arm for aerospace applications. The proposed fault-tolerant drive system adopts a dual-winding fault-tolerant (DF) motor; the DF motor offers the advantages of magnetic isolation, physical isolation, thermal isolation, small cogging torque ripple, inhibiting the short-circuit current and high fault tolerance. The proposed fault-tolerant drive can adapt to the single power supply system of the aircraft, reduce the drive cost, and cut down the number of independent power sources and power switches. In addition, it can improve the power density, reliability, and the utilisation rate of the drive system. To realise the open-circuit fault diagnosis performance, the diagnosis and processing method of the opencircuit fault has been investigated. Then, to realise the fault-tolerant performance, a novel space-vector pulse-width modulation (SVPWM) fault-tolerant control strategy is proposed. Finally, the performances of the fault-tolerant drive have been verified by simulations and experiments. The research results verify the reliability and effectiveness of the proposed fault-tolerant drive system based on the redundancy bridge arm and SVPWM fault-tolerant control strategy. Fig. 8 Experimental results of the fault-tolerant drive based on the redundancy bridge arm (a) Measured waveforms under normal condition, (b) Measured waveforms under phase-A open-circuit, (c) and (d) Measured waveforms under phase-A open-circuit condition when the proposed control strategy is adopted
