Thi s paper presents the development of Wind Turbine Emulator (WTE) for wind energy conversion systems (WECS), using a separately excited DC motor, controlled by a chopper and real-time interface card. The DC motor is controlled using PI regulator. The wind turbine emulator system inc\udes wind speed profiles, mathematical model of wind turbines, modeling of rotor blade characteristics and modeling of rotor inertia. Wind speed can be easily programmed. The proposed approach was implemented on DSl104 real-time interface card and Matlab/Simulink real-time control programming. The experimental results show the performance of proposed WTS.

This paper focuses upon an approach to generate the electrical energy from wind by mounting specially designed wind turbines on the roof of moving rail locomotives (trains). In this work, three blade wind turbine system constructed using aerofoil is proposed. In proposed model, wind turbine is arranged in bus bar arrangement. The power developed by the implementation of aforementioned design is used to fulfil all the requirements for electrical appliances of a train coach (tube lights, fans etc). The aim of this research paper is to exploit the kinetic energy of air for generation of electrical energy, by implementing suitable arrangements on large vehicles. This technology will help reduce drastically, the fuel consumption required for the electrical power generation.

“…increase voltage) converters. Other research teams have developed ways to control WT voltage using buck, boost, and buck/boost converters: Arifujjaman et al (2006), Tafticht et al (2006, Hu et al (2008), Ni et al (2009), and Qiang et al (2011). Although each of these control/converter systems had their advantages for different applications, we decided that we will add a controller and a buck/boost converter arrangement to our existing hybrid WT/PV water pumping system which is similar to what Qiang et al(2011) used since their experiment demonstrated a relatively constant voltage (only 3% ripple) even though the WT input DC voltage varied from 20 to 100 V. A schematic of our proposed control loop is depicted in Fig.…”

While many remote water pumping systems exist (e.g. mechanical windmills, solar photovoltaic, wind-electric, diesel powered), few combine both the wind and solar energy resources to possibly improve the reliability and the performance of the system. In this paper, off-grid wind turbine (WT) and solar photovoltaic (PV) array water pumping systems were analyzed individually and combined as a hybrid system. The objectives were to determine: (1) advantages or disadvantages of using a hybrid system over using a WT or a solar PV array alone; (2) if the WT or solar PV array interfered with the output of the other; and (3) which hybrid system was the most efficient for the location. The WT used in the analysis was rated at 900 W alternating current (AC). There were three different solar PV arrays analyzed, and they were rated at 320, 480, and 640 W direct current (DC). A rectifier converted the 3-phase variable voltage AC output from the WT to DC before combining it with the solar PV array DC output. The combined renewable energies powered a single helical pump. The independent variable used in the hybrid WT/PV array analysis was in units of W/m 2. The peak pump efficiency of the hybrid systems at Bushland, TX occurred for the 900 W WT combined with the 640 W PV array. The peak pump efficiencies at a 75 m pumping depth of the hybrid systems were: 47% (WT/320 W PV array), 51% (WT/480 W PV array), and 55% (WT/640 W PV array). Interference occurred between the WT and the different PV arrays (likely due to voltage mismatch between WT and PV array), but the least interference occurred for the WT/320 W PV array. This hybrid system pumped 28% more water during the greatest water demand month than the WT and PV systems would have pumped individually. An additional controller with a buck/boost converter is discussed at end of paper for improvement of the hybrid WT/PV array water pumping system.
