In this paper, the authors investigated a Direct Drive Permanent Magnet Synchronous Generator Wind Turbine (PMSG-WT). This study deals with control of the PWM back-to-back converter (AC/AC) of the wind turbine, since the average size of WTG installations has increased due to the advent of larger capacity machines, especially variable speed technology, this raise of integration rate of wind ener...

This paper deals with the problem of interfacing a wind turbine generator with an electrical three phase grid in the presence of nonlinear loads. Wind systems are generally connected to the grid through an AC/DC inverter in the generator side, followed by a DC/AC converter in the grid side. In this work, the considered DC/AC converter is based on multilevel neutral point clamped topology, and w...

AC motors play a vital role in industrial and domestic applications. Due to different tasks of application, most of the industries need to have variable speeds of operation of AC motors using Variable Frequency Drives (VFDs). The operation of VFDs is controlled by control signals from reference signal generator. Here, it has to be noted that transfer of analog control signal to the electric dri...

This work presents power generation using Attic type (internally braced) air exhauster to generate the electrical power for industrial application. Generally power can be generated from renewable and non-renewable energy sources like solar, wind, tidal, geothermal, coal, natural gas and petroleum. To satisfy the growing power demand the industry focuses on alternate energy sources like wind dri...

Labeling of specific antibodies with bifunctional chelated Actinium-225 ((225)Ac; an alpha generator) allows the formation of new, highly potent and selective alpha-emitting anticancer drugs. We synthesized and evaluated a radioimmunoconjugate based on 3F8, an IgG(3) antibody that specifically binds to ganglioside GD2, which is overexpressed by many neuroectodermal tumors including neuroblastom...

This paper presents the comparative analysis of improved quality three phase AC/DC boost converters, using SIMULINK. Comparison of three phase controlled single switch and six switch AC/DC boost converters have been done to identify the boost converter with low cost/small size/high efficiency for three phase system. Three phase AC/DC boost converters with improved quality in terms of power fact...

A sustainable residential microgrid composed of two distributed generation sources (photovoltaic panels and biofuel generator), one energy storage device (battery bank), and able of supplying both AC and DC loads, including a plug-in hybrid electric vehicle, is proposed. The microgrid can operate in grid-connected mode and island mode. It is composed of a main DC bus and also an AC bus. The cha...

Power generation using small wind turbines connected to AC grids has been gaining attention and contributions in recent years. As are remote areas as support energy systems, there not extensive connecting those grids. This paper presents the integration of a system which is AC-grid-connected. The composed 160 W commercial turbine with permanent magnet synchronous generator 140 Texas Instruments...

This paper treats an induction machine as a wind power generator, and voltage deviation due to wind velocity change is simulated by a dynamic stability calculation program. The ac bus voltage connected to the wind generator highly depends on the wind velocity variation. Then author actually measured the wind velocity which is used for the simulation. This paper shows 1 second sampling data of t...
