Abstract:

The UK has committed to sourcing 15% of its energy from renewable sources by 2020 and wind turbines have the potential to contribute towards this target. Due to the Feed-In-Tariffs introduced by the UK Government in 2010, the potential uptake of micro-generation methods such as small wind is likely to increase. However, many barriers exist which prevent widespread implementation, such as noise concerns. There is little work available in the open literature quantifying the problem because much of the existing research focuses on large scale turbines. The need for an increase in interdisciplinar

Abstract:

This paper investigates the concept of an isolated small wind power system based on a three-phase generator and a direct ac-to-ac conversion. The ac-to-ac conversion is performed by a matrix converter and thus removing the need of a large smoothing capacitor in the typical rectifier-inverter solution. The paper is briefly presenting the operation for a particular topology of a three-phase to single-phase matrix converter. The control of this conversion ensures system’s frequency and voltage stability. Simulation results and practical results are presented to validate the frequency and voltage

Abstract:

Small-scale renewable energy systems are becoming increasingly popular due to soaring fuel prices and due to technological advancements which reduce the cost of manufacturing. Solar and wind energies, among other renewable energy sources, are the most available ones globally. The hybrid photovoltaic (PV) and wind power system has a higher capability to deliver continuous power with reduced energy storage requirements and therefore results in better utilization of power conversion and control equipment than either of the individual sources.

The aim of the research is to produce a methodology for the siting of small-scale, embedded wind generators, and implement this within a commercial software package designed to use existing digital data sets.

Much of the information required for such a siting study is spatial in nature and hence the site identification process can be facilitated using a geographical information system - GIS.

A major research challenge is that many contemporary methods provide a restricted spatial resolution or coverage of variations of ABL properties such as how wind speed varies across a landscape with complex topography.

As wind turbines are increasingly being adopted for meeting growing energy needs, their implementation for personal home use in the near future is imminent. There are very few studies conducted on small-scale turbines in the one to two meter diameter range because the power generated at this scale is currently not sufficient to justify the cost of installation and maintenance. The problem is further complicated by the fact that these turbines are normally mounted at low altitudes and thus there is necessity to have the optimum operating regime in the wind speed range of 3-10 mph (1.34 -- 4.47

Small wind turbines, and especially urban-mounted turbines which require no dedicated pole, have garnered great public enthusiasm in recent years. This enthusiasm has fueled widespread growth among energy conservationists, and estimates predict that the power produced nationally by small wind will increase thirty-fold by 2013. Unfortunately, most of the wind resources currently available have been designed for larger, rural-mounted turbines; thus, they are not well suited for this nascent market. A consequence of this is that many potential urban small wind turbine owners over-predict their l

Generally, visual tracking algorithms are tuned to detect motion of relatively large objects in the scene with noticeably significant motion; therefore, applications such as high-altitude visual searches for human motion often ignore target motion as noise. Furthermore, after a target is identified, arbitrary maneuvers for transitioning to overhead orbits for better observation may result in temporary or permanent loss of target visibility. W

碩士<br>清雲科技大學<br>電機工程所<br>98<br>This thesis a small-scaled vertical axis wind power generation system was development. In the wind turbine side, the maximum power point tracking method was adopted to control the DC/DC boost chopper to achieve optimum maximum power output and enhance conversion efficiency. In the batteries side, a boost dc chopper was used to get the maximum power association with variation wind speed from the wind power generation system and supply power to batteries charge. Finally, DC power can be transformed into AC power by a single phase full-bridge inverter. The voltage s

Specifically, this study investigates the characteristics matching problems between the rotor blade and generator, and develops a generator output control system using a micro-controller. The characteristics of some available generators are tested using a generator test bench. These generators are combined with the existing rotor blades to evaluate the matching availability. The controller designed of this system uses a microchip PIC1

Cars using fossil fuel are facing critical challenging dioxide produced by combustion when driving the car is making green house effect increasingly serious. Therefore, it’s very important to design a vehicle that can be partly driven by alternative energy. The perspective of the study is to recycle wind energy when a car is moving and develop small wind power generator which can be used by

Abstract:

Approaching problems with global warming due to the use of fossil fuels, means that new system solutions have to be investigated. This report investigates the possibility to expand an existing photovoltaic system with a wind turbine generator to simplify the expansion of renewable energy sources. Through an extensive literature study and simulation in SIMULINK the result has been developed and tested. It shows that it is possible to connect a wind turbine generator to the same inverter as the PV-modules if no MPPT algorithm for the PV-modules is integrated. To protect the inverter a dump load
