Abstract— This paper analyses the working of a stand-alone vertical wind turbine system with a Permanent Magnet Alternator (PMA) and a secondary system consisting of an energy storage device for storing energy during wind speed variations. The ancillary system is necessary to support the primary system and improve its reliability under drastic conditions. Initially‚ the entire system is modeled with the VIENNA Rectifier‚ and the storage system‚ excluding the PMA. The output power required by the

Here we discussed in Detail about Wind Energy and the production of electricity from moving vehicles. So first we defined Energy. Till Now we have studied that energy is the ability of a body to do work .it can also be defined as the ability of a body to bring some change is the energy of that body. Energy is very necessary for human beings; every thing in the universe possessed some energy. There are two main kinds of Energy 1. Kinetic Energy 2. potential Energy Kinetic energy is produced

About Small Wind Turbine Wind turbines convert wind energy into electrical or kinetic energy. Small wind turbines are used for the micro-generation of energy mainly to small-scale commercial customers and residential customers. The blades of small wind turbines are usually 2-8 m in diameter. These turbines can generate between 0.01 KW and 100 KW of power. Small wind turbines are used to meet small-scale energy demands from end-users such as residential customers‚ schools‚ small commercial and

Pumping Systems: Parallel and Series Configurations For some piping system designs‚ it may be desirable to consider a multiple pump system to meet the design requirements. Two typical options include parallel and series configurations of pumps. Specific performance criteria must be met when considering these options. Given a piping system which has a known design flow rate and head requirements‚ Qdes‚ hdes‚ the following pump selection criteria apply. Pumps in Parallel: Assuming that the pumps are

3.7 Wind Generators: There are three main parts in horizontal axis wind turbines: (1) a rotor‚ (2) an alternator‚ and (3) a tail. The rotor blades are attached to a central hub covered by a nose cone that improves aerodynamics. Three blades are generally present in upwind generators. This entire assembly rotates when wind blows past the blades‚ hence the name “rotor.” In many small wind turbines the rotor is coupled to a shaft which is coupled to an alternator‚ a device that produces AC electricity

Wind Energy A turbine is machine that spins arounds catching energy that’s passing by. The huge rotor blades (propellers) on the front of a wind turbine are the "turbine" part. As wind passes by‚ the kinetic energy (energy of movement) it contains makes the blades spin around (usually quite slowly). The blades have a special curved shape so they capture as much energy from the wind as possible. Although we talk about "wind turbines‚" the turbine is only one of the three main
