free - 200 watt permanent magnet wind generator - ebook
SKU: f2wpmg/ebook/000

This manual describes how to build a 'permanent magnet generator' (PMG). We can also call it an 'alternator', because it generates alternating current (AC). It will not generate 'mains voltage' or 'utility power' AC. It generates low voltage, 'three phase' AC, and then changes it into 'direct current' (DC) for charging a 12 volt battery.

Alternator secrets - ebook
SKU: as/ebook/0/0

In the last two decades alternators have replaced generators in motor vehicles. The reasons are many: output current can be produced at lower rpm, voltage can be more accurately' controlled with solid state regulators, alternators need less maintenance, and they cost less to manufacture.

When modified, auto alternators can provide variable direct current at 0 to 120 volts for battery charging, hot charging, light arc welding, or for running AC-DC appliances and lights. Another simple modification provides AC power to run some transformer-operated appliances. If you know the secrets of its operation and the modifications possible, the small low-cost alternator can become a versatile power plant.

Surprisingly, alternators are constructed with three sets of field windings positioned evenly at 120 degree intervals inside the frame. Such construction produces three-phase AC.

Rewiring Generators as Alternators
SKU: rga/ebook/000/000

Wind generators run at fairly slow speeds: usually 250 to 600 rpm. Most people who design their own wind systems are stymied by the unavailability of slow speed generators. They usually choose to use an off-the-shelf generator that is stepped up to operating speed from the relatively slow propeller speed of a wind generator. But stepping up with gears, chains or belts introduces large inefficiencies, not to mention more moving components that need maintenance. There is another way around this problem: rewinding the alternator or generator for slow speed operation.

Batteries - simple guide to batteries - free ebook
SKU: bsg/ebook/000/00

As many small-scale methods of electricity generation are available only intermittently, some form of electricity storage or battery is needed if people want to have electricity available at all times.

There are a wide range of batteries available, and the aim of this Technical Brief is to give an introduction to the advantages and disadvantages of the different types of batteries. The central point is that there is no such thing as a universal battery; a single type of battery cannot cover all applications.

Can migrogrids make a major contribution to UK energy supply - ebook
SKU: cmmac/ebook/000

Almost all the electricity currently produced in the UK is generated as part of a centralised power system designed around large fossil fuel or nuclear power stations. This power system is robust and reliable but the efficiency of power generation is low, resulting in large quantities of waste heat. The principal aim of this paper is to investigate an alternative concept: the energy production by small scale generators in close proximity to the energy users, integrated into microgrids. Microgrids – de-centralised electricity generation combined with on-site production of heat - bear the promise of substantial environmental benefits. This is brought about by a higher energy efficiency and by facilitating the integration of renewable sources such as photovoltaic arrays or wind turbines. By virtue of a good match between generation and load, microgrids have a low impact on the electricity network, despite a potentially significant level of generation by intermittent energy sources. The paper discusses the technical and economic issues associated with this novel concept, giving an overview of the generator technologies, the current regulatory framework in the UK, and the barriers that have to be overcome if microgrids are to make a major contribution to the UK energy supply. The focus of this study is a microgrid of domestic users powered by small Combined Heat and Power generators and photovoltaics. Focusing on the energy balance between the generation and load, it is found that the optimum combination of the generators in the microgrid - consisting of around 1.4 kWp PV array per household and 45% household ownership of micro-CHP generators - will maintain energy balance on a yearly basis if supplemented by energy storage of 2.7kWh per household. We find that there is no fundamental technological reason why microgrids cannot contribute an appreciable part of the UK energy demand. Indeed, an estimate of cost indicates that the microgrids considered in this study would supply electricity at a cost comparable with the present electricity supply if the current support mechanisms for photovoltaics were maintained. Combining photovoltaics and micro-CHP and a small battery requirement gives a microgrid that is independent of the national electricity network. In the short term, this has particular benefits for remote communities but more wide-ranging possibilities open up in the medium to long term. Microgrids could meet the need to replace current generation nuclear and coal fired power stations, greatly reducing the demand on the transmission and distribution network.

Autopower - Generator Secrets
SKU: cam/gs/118/400
Lindsay Publications says - We had this a while ago, when it was called by its original title - Autopower, and it is good. Here you get secrets from the 1930's about taking a generator and converting it into a 110 volt AC alternator that could power a farm or home; the opening chapters give detailed instructions for rewinding a Ford Model A, Model T, and Dodge Type G generators. Later chapters talk about the general principles that can be applied to almost any generator. That's where the real value of this small book lies. It is not applicable to modern alternators. You must start with an old generator and go from there. Obviously, you won't use a Ford Model A or T or even an early Dodge. You'll use what you can find. And generators are still available at scrap yards on old vehicles, even on eBay at reasonable cost. Useful information. 56 page, well illustrated paperback. Lindsay Publications

Energy Transmission and Grid Integration of AC Offshore Wind Farms
SKU: etgiowf/000/ebook/000
This book analyses the key issues of the offshore wind farm's energy transmission and grid integration infrastructure. But, for this purpose, there are not evaluated all the electric configurations. In the present book is deeply evaluated a representative case. This representative case is built starting from three generic characteristics of an offshore wind farm: the rated power, the distance to shore and the average wind speed of the location. Thus, after a brief description of concepts related to wind power and several subsea cable modeling options, an offshore wind farm is modeled and its parameters defined to use as a base case. Upon this base case, several analyses of the key aspects of the connection infrastructure are performed. The first aspect to analyze is the management of the reactive power flowing through the submarine cable. Then, the undesired harmonic amplifications in the offshore wind farms due to the resonances and after this, transient over-voltage problems in the electric infrastructure are characterized. Finally, an offshore wind farm connection infrastructure is proposed in order to achieve the grid code requirements for a specific system operator, but not as a close solution, as a result of a methodology based on analyses and simulations to define the most suitable layout depending on the size and location of each offshore wind farm.

Third Generation Photovoltaics
SKU: SKU18604
Photovoltaics have started replacing fossil fuels as major energy generation roadmaps, targeting higher efficiencies and/or lower costs are aggressively pursued to bring PV to cost parity with grid electricity. Third generation PV technologies may overcome the fundamental limitations of photon to electron conversion in single-junction devices and, thus, improve both their efficiency and cost. This book presents notable advances in these technologies, namely organic cells and nanostructures, dye-sensitized cells and multijunction III/V cells. The following topics are addressed: Solar spectrum conversion for photovoltaics using nanoparticles; multiscale modeling of heterojunctions in organic PV; technologies and manufacturing of OPV; life cycle assessment of OPV; new materials and architectures for dye-sensitized solar cells; advances of concentrating PV; modeling doped III/V alloys; polymeric films for lowering the cost of PV, and field performance factors. A panel of acclaimed PV professionals contributed these topics, compiling the state of knowledge for advancing this new generation of PV.

How to build a Thermo-electric generator
SKU: Htbateg/ebook/000
This thermoelectric generator was designed to charge a mobile phone (like my last version). Because I do not want the peltiers to over heat and melt like they have before, I was weary of having the flame too close to the peltiers. The thermoelectric generator failed to produce enough power to charge a mobile phone, it does produce enough to power a small radio or some bright LED lights. This version is much more reliable than my last one due to the better heat sink it doesn't run anywhere near as hot so the life of the peltiers should be quite long.

Lithium-ion Batteries
SKU: lib/ebook/000
There have been numerous excellent books on LIBs based on various different viewpoints. But, there is little book available on the state of the art and future of next generation LIBs, particularly eventually for EVs and HEVs. This book is therefore planned to show the readers where we are standing on and where our R&Ds are directing at as much as possible. This does not mean that this book is only for the experts in this field. On the contrary this book is expected to be a good textbook for undergraduates and postgraduates who get interested in this field and hence need general overviews on the LIBs, especially for heavy duty applications including EVs or HEVs.

Energy Storage
SKU: es/intech/ebook/000
Electricity is more versatile in use because it is a highly ordered form of energy that can be converted efficiently into other forms. However, the disadvantage of electricity is that it cannot be easily stored on a large scale. One of the distinctive characteristics of the electric power sector is that the amount of electricity that can be generated is relatively fixed over short periods of time, although demand for electricity fluctuates throughout the day. Almost all electrical energy used today is consumed as it is generated. This poses no hardship in conventional power plants, where the fuel consumption is varied with the load requirements
