A Vortex wind generator, small and portable, is used for many reasons, in the home, at work, in your vehicle, or to power your boat and its accessories PowerMax 1KW Wind Generators The great thing about the PowerMax 1KW Wind Generators is that it is easy to set up and quite affordable 600W/24V WindMax Residential Wind Turbine Wind GeneratorThe pod takes air and funnels it into a smaller exit than in a normal turbine, which speeds it up before it hits the internal blade. Wind can enter from multiple directions at once too, something which can often cause regular turbines to shatter.Yes, thats right, Trinity is a portable wind turbine.

It shows that Powerpods have the potential to produce equal or greater power than their more expensive solar counterparts. вЂњThey are also ugly, in our opinion,вЂќ says Hodges. Is it really more efficient?UPRISE Energy has developed an innovative 50kW wind energy generator the machine is powerful, efficient, and portable.

Several large manufacturers have installed MW sized wind turbines at their facilities. Mid-range units (50 kW to 1 MW) have found application in very remote sites such as the Antarctic, but application has not been widespread.Interest by commercial and industrial consumers in own generation has led to the development of medium sized wind turbines, which are often used in combination with solar PV systems, and in many cases are less expensive than solar PV. The sub-megawatt range is however less well known but is a developing market for the private generation sector.Small wind turbines in the tens of kW power range have been in use for many years for telecommunications sites and other small low power applications.

There are some applications that can operate independently of the time availability of the resource, and for these, wind could be ideal.The cost of renewables is often compared on a general basis using optimum conditions of resource availability, such as optimum solar and optimum wind. One of the downsides compared to solar could be the variable nature of wind, but at a well-defined site with a predictable wind pattern which matches the demand of the customer, wind can have a significant advantage. For example a 300 kW turbine has a footprint of about 144 m2, while a PV system with the same rating would require about 2000 m 2.Fig.

Permanent magnet generators are making inroads into the utility scale wind turbine market, but the optimum sector for these machines is in the small to medium sector.The AC output is fed to the full scale power converter as shown in Fig. The turbine generates an AC output whose frequency and voltage depend on the speed of rotation of the turbine blades. The other issue not shown in the solar radiation map is the occurrence of consecutive days of low solar radiation in these areas, which negates the possible advantage of energy storage.The prime technology used in this range of wind turbines is the permanent magnet generator, where the magnetic field is provided by permanent magnets, and not by stator coils. This makes wind an attractive option for coastal and near coastal towns. 1 a and b), it can be seen that, with the exception of the Western Cape coast, coastal areas tend to have relatively low solar radiation, while wind resources are relatively high.

Until recently, a wind turbine that incorporated a gearbox, was less expensive than a wind turbine that did not, because of the cost savings that came from having a higher speed generator. 2: Full scale power converter. The output frequency and voltage are independent of the speed of the turbine blades, and the only variant is output power.Fig.

It is coupled directly to the turbine shaft. The development of high power electronics devices, on which the full scale power converter depends.The generator is not coupled to a gearbox but is of a type known as direct drive, i.e. The availability of high performance permanent magnet material. This type of technology has been made possible by two things: This change has been caused by two technical advancements: the cost of permanent magnets has declined significantly, and the arrangement of the generator has become more streamlined.

The stator consists of windings on the iron core pole pieces. The rotor contains permanent magnets arranged in pairs of opposite polarity. Smaller blade size allows faster rotation (blade-tip speeds below the speed of sound).The construction of a low speed PMG is shown in Fig 3.

Using a large number of magnets requires a large rotor and stator diameter, and sizes of three to six metres are common. Various combinations of magnets and placement of magnets to achieve different operational requirements, but all operate on the same basic principle. Stator windings would normally be connected in series to give single or three phase outputs.There are a number of different configurations from the simple on shown in Fig. For instance if the generator shaft rotates at 50 rpm and the generator has 50 poles the effective or virtual speed will be 2500 rpm. For a slow shaft speed, the number of poles will affect the effective or вЂњvirtualвЂќ rotations speed of the generator. The frequency and induced voltage will depend on the time taken for a magnet pair to move past a pole.

With lower structural loads and, axial-flux PMGs without an iron core can also increase efficiencies, particularly at lower wind speeds. The electromagnetic concept in an axial flux generator operates similarly to a radial flux generator, but the lack of an iron core removes the attractive forces between the rotor and stator вЂ“ the absence of which means lower structural loads and large weight reductions, even as power ratings grow. 3: Permanent magnet generator construction.PMGs for wind turbines are usually constructed using a radial flux configuration where the magnetic field is applied radially inward and outward from the rotor, but there has been some development towards the use of axial flux machines, where the magnetic field is applied along the rotor axis. This all makes the design of the generator simpler than that of a high speed generator.Fig.

The residual flux density of permanent magnets used in a typical large wind turbine is of the order of 1,2 Tesla (12 000 Gauss).A full-scale converter (FSC) for wind turbine systems, is one in which all power extracted from the wind is managed and transferred to the utility grid by a power electronics converter. They are not easily machined, and are produced for the general market in standard shapes and sizes. Their mechanical properties more closely resemble a ceramic, rather than a metal. This equates to approximately 0,6 kg/kW produced.The magnets are manufactured to the size and shape required by the turbine manufacturer, using powder metallurgical methods, such as sintering of the fine particles produced by the alloying process. A 3,5 MW turbine uses 2000 kg of high energy neodymium-based (Nd-Fe-B) permanent magnet material. Neodymium is a rare earth material, with an atomic number of 60.Neodymium alloy magnets are the strongest magnets produced.

The converter has the capability of handling a variable fundamental frequency and the generator output voltage to control the speed. Thus, by using this converter, any of the required control can be implemented. This converter performs the function of controlling the current through the generator thereby controlling torque and in turn the rotating speed. The generator side conversion stage can control maximum power point tracking. 2).There are two stages of the conversion, each of which is controlled separately.
