With the installed volume on wind farm increasing constantly, the impact of wind electricity on public grid has become increasingly evident, which superimposes more and more importance on the study on wind power integration to grid. A solid state transformer (SST) based induction wind power generator grid-connected system is put forward in this paper. The lumped parameter mathematical model of the induction wind power generator, input side controlled rectifier, output side inverter and middle stage high-frequency transformer are constituted respectively. System working principle at power flowing forward and backward status are analysed and the control strategy of each module is designed afterwards. A system simulation model is built based on topologies and control strategies discussed above. It is seen from the results that the newly designed system is of good working performance. The grid connecting current is sinusoidal and the unity power factor control is achieved. Output voltage and DC bus voltage are stable during the operating process. During voltage sag caused by grid faults, energy storage devices connected to the SST discharge to sustain the low-voltage DC bus voltage, enhancing the system low voltage ride through (LVRT) capability.

The paper is devoted to an approach to optimize the stator circumferential geometry of a five phase fractional-slot PM synchronous machine (FSPMSM). The proposed approach is initiated by a formulation of the armature MMF considering a sinusoidal current supply that matches the surface-mounted arrangement of the PMs. An investigation of the harmonic content of the armature MMF enables the analysis of its total harmonic distorsion versus the stator circumferential geometry. Then, the cogging torque is formulated and its variation with respect to the circumferential geometry is explored. The obtained results are validated by FEA. Finally, an optimal stator circumferential geometry is selected considering as criteria an increased average value of the electromagnetic torque, and a decreased peak-to-peak value of the cogging torque.

Replacing the conventional cars with electric vehicles is generally considered a promising solution for the up-to-date energy shortage and atmospheric pollution problems. Loss is generated all the time in the traveling process of electric vehicles and it is eventually transformed to heat dissipating in ambient environment. Thermal management is a critical part in electric vehicle research to timely take away the heat, ensuring the system work properly. A self-adaptive cooling system with cooling fan and coolant pump being controlled adopting fuzzy law is proposed in this paper. The structure and parameters of the fuzzy controller are designed according to the actual cooling system working conditions. Simulation model is constructed in Matlab/Simulink environment based on the topology and control strategy studied above. Experimental prototype, including two permanent magnet synchronous motors (PMSM), power converters, control box, cooling fan and coolant pump are all manufactured and tested. The design scheme is verified by the testing results.

In this study, an engine on/off and engine operation control algorithm to improve the fuel economy was proposed for a PHEV(plug-in hybrid electric vehicle) considering driver tendency. To identify the driver tendency, a driver model was developed using VIDE (virtual integrated development environment). The target vehicle model was developed based on MATLAB/Simulink and validation of the vehicle model was performed by experiments. Using the VIDE, real drivers who have different tendency drive the PHEV in virtual environment and driving data were accumulated. Using the driving data, the driver model which can reflect the driver tendency was developed. To describe the driver tendency, degree of driver aggression (DDA) was proposed, which was determined by fuzzy logic. The DDA was applied to the PHEV control algorithm to improve the fuel economy. This algorithm controls the engine on/off and engine operation, which provides the improved fuel economy.

The impedance represents one of the most important performance parameters of the Lithium-ion batteries since it used for power capability calculations, battery pack and system design, cooling system design and also for state-of-health estimation. In the literature, different approaches are presented for measuring the impedance of Lithium-ion batteries and electrochemical impedance spectroscopy and dc current pulses are the most used ones; each of these approaches has its own advantages and drawbacks. The goal of this paper is to investigate which of the most encountered impedance measurement approaches is the most suitable for measuring the impedance of Lithium-ion batteries during ageing.

In the context of a BMBF joint project an electric vehicle with decentralized direct drives was developed at Ostfalia University of Applied Sciences. In order to enable energy-optimized operation as well as maximum driving safety while factoring in the interactions between electrical traction and vehicle-dynamics controls, an electronic vehicle management was laid out in a model-based manner. This vehicle management integrates the functionalities of drive-, chassis and energy management and is structured hierarchically. It comprises two subordinated control structures: a chassis management and an electrical energy management, each of them comprising other local information-processing units. The focus of the present paper is on the model-based function layout of the cooperative braking system with the hierarchically subordinated control of the traction machines and friction brakes.

Batteries drawbacks are represented by the high cost, the limited reliability and the frequent maintenance requirements (recharge or replacement). Energy Harvesting (EH) offers an alternative to batteries replacement or, at least it allows the increase of their lifetime. EH is the conversion of ambient energy, which is present in the environment, into electrical energy. Different energy sources for EH applications have been reported in the literature: light, radio frequency (RF), temperature gradients, solar energy, vibrations. In this paper we will focus on vibration EH. In a Vibration Energy Harvester (VEH) electrical energy is generated by allowing an inertial mass to vibrate with respect to a frame. In this paper a closed-form analysis of the model of a single-degree of freedom Out-of-Plane Switchless Electrostatic Vibration Energy Harvester (SEVEH) will be presented and discussed. We will demonstrate that, under suitable reasonable assumptions, it is possible to study SEVEHs by using models that admit closed form solutions and, at the same time, are enough accurate if the simplifying hypothesis are met. In particular, a circuital model will be developed which describes both the mechanical and the electrical subsystems composing a SEVEH.

Hybrid electric ship propulsions are becoming a leading/emerging area of research, prompting investigation in hybrid propulsion system design and demonstration of concept vessels. With respect to ship design and operation, minimizing costs associated with fuel consumption and maintenance are key objectives. As such, new, and existing, ships are subject to regulatory requirements, especially regarding emissions and energy efficiency. Hybrid electric propulsion is a promising approach in addressing these concerns. Particularly for inland vessels that require a high degree of manoeuvrability and are continuously travelling upstream and downstream. In this work, a Permanent Magnet propulsion motor with 350kW at 300rpm, hence around 11,000Nm, will be discussed. With this motor a quiet mode is available with reduced emission during electric cruising and dynamic positioning.

The paper proposes two novel direct torque control (DTC) strategies dedicated to three-switch three-phase inverter (TSTPI) fed induction motor (IM) drives. The TSTPI generates six asymmetric active voltage vectors in the stationary plane: (i) three high-amplitude vectors and (ii) three low-amplitude vectors. Suitable combinations of the three high-amplitude voltage vectors are considered in the vector selection table of the first DTC strategy. While, the second one considers the subdivision of the stationary plane into six sectors. This approach is similar to the one adopted in the Takahashi DTC strategy dedicated to IM drives fed by the conventional six-switch three-phase inverter (SSTPI). A simulation-based comparison between both DTC strategies has highlighted the superiority of the second DTC strategy especially with respect to the motor current distortion.

This study presents the results of electromagnetic field parameters measurements in an open area under different air temperature and humidity conditions. An attempt to consider the electromagnetic wave as a holistic harmonic oscillation, which takes into account all frequency components of the field at the measurement point, was also presented in this study. During the measurements, the closest electromagnetic radiation sources were taken into account. Therefore, measurements of field parameters were produced in specific frequency bands. For the simplification of large data, the spectrum decimation technique was applied. As a result, measurements and data processing were revealed to characterize the electric field strength and the magnetic flux density when air temperature increases. The field parameters dependences on air relative humidity have a decreasing tender.
