What is Wind generator: Definition and 15 Discussions

A wind turbine is a device that converts the wind's kinetic energy into electrical energy.
Wind turbines are manufactured in a wide range of sizes, with either horizontal or vertical axes. It is estimated that hundreds of thousands of large turbines, in installations known as wind farms, now generate over 650 gigawatts of power, with 60 GW added each year. They are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels. One study claimed that, as of 2009, wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and... the most favourable social impacts" compared to photovoltaic, hydro, geothermal, coal and gas.Smaller wind turbines are used for applications such as battery charging for auxiliary power for boats or caravans, and to power traffic warning signs. Larger turbines can contribute to a domestic power supply while selling unused power back to the utility supplier via the electrical grid.

    Measuring the current from a micro generator affects its output?

    I am performing an experiment where I have built a scale model of a wind turbine, and am measuring the current it can produce with a micro generator. I am using a standard multi meter and the micro generator is DC. I do not know much about the topic, but whenever I start measuring the current...

    Choosing a wind turbine generator

    I'm doing a school project in which I'm building a wind turbine. The next step for me is to choose a generator but I'm not completely sure what is right for me. I expect to come up to 300 rpm as an average and need the required voltage to for a car battery, which is around 14.4 volt. My...

    What generator/DC motor do I need for my wind turbine

    I am making a small wind turbine for my A-level RMT and wondering what kind of generator I need to charge a 12volt battery. The turbine is a vertical axis savonius turbine that will probably be about a meter high and half a meter wide. I know I can use permanent magnet dc motors and someone...

    Need help for project plans (Solar and Wind Generator)

    Hi, I'm trying to build an auto-sufficient station, this is my "blueprint" for mounting everything together : https://goo.gl/photos/4KLmhUc9EDccMPkYA and I would like to know if it was possible to calculate the voltage and intensity entering the Charge Controller without measuring it, if...

    Recharging a battery when Lightbulb and TV are in parallel

    Homework Statement In a household, the wife reads a book that uses a light bulb that has a resistance of 100Ω and is connected to a 100 V line while the husband watches a TV that draws 100 W of power. They do these actives for 200 mins. Power comes from a wind generator that charges batteries...

    Vertical Wind Tunnels using green technology

    I wish to create a state-of-the-art vertical wind tunnel for indoor skydiving. By state-of-the-art I mean using green technology to create the power necessary to push air, and I would like to reclaim as much energy I can from the movement of air, drive shafts, and anything else I have not...

    Wind turbines with many small generators

    Hello, This is not a homework question. I'm not a student. In fact I'm retired. The other day, I was passing by a wind turbine. I thought "wouldn't it be better to have hundreds of small generators with small wings connected together instead of one huge generator with huge wings?" But I did...

    Quick question about DC Motors

    Hi, I'm doing research for my science project. I chose Wind energy and I need to learn a few things about DC Motors, Who is a good manufacturer for 6-9V .5 amps DC motor/generators? What happens if the generator goes over the recommended RPMs? How do you keep the RPMs between the minimum...

    New to building a wind generator -- Need help

    I thought it is easy when I was watching all sorts of instruction videos. However, now I have Fisher and Paykel stator and rotor, and I cannot solve how rotor is suppose to spin. The magnets are so strong that I do not think any wind will be able to move it. When I received my parts, I had hard...

    Building a Wind Generator with a DC Motor

    Hi everyone. This is my first time trying this. So please be gentle. My question is to do with a dc motor. I want to build a wind generator and I am trying to figure out what size motor to start with and try to size the blades to get the best out of it. I know that their is a lot of other...

    Very Large Scale Wind Generator

    Renewable Energy (RE) Sources are a hot topic, but careful study of the solutions thus far offered make realizing RE as more than a tiny percentage of demand unrealistic. I have been thinking on an idea for a very large scale wind generator that I think is a potential solution for many of the...
