If you have a high roof that gets enough wind speed on a regular basis then you may well consider installing a roof mounted wind turbine. They vary in power from about 0.5 kW to 2.5 kW and can be used to supplement your electricity supply. Before you take the option of getting a roof mounted turbine you need to. . For those that are serious about using wind as a means of providing renewable energy for a local source and perhaps benefitting from the Feed in Tariff, free-standing wind turbines. . Finding the initial outlay for your wind turbine development can often be a problem. There are a number of financial institutions and grants available that you can now take advantage of if you are serious about using wind. . If you are a business you may have to pay a levy or tax on the energy such as gas, electricity or coal that you is used in the day to day running of your company. If you install a renewable energy. . One of the attractive things about installing a renewable energy source is the chance it gives you to sell your excess electricity to the power companies and make a decent return on investment.

The mechanical power extracted from wind turbine can be expressed as: where \rho is the air density, R is the radius of the turbine, v is the wind speed, C_p(\lambda ) is the power coefficient and \lambda is the tip-speed ratio (TSR).. . Since Eqs. (5) and (8) do not contain the stator voltage explicitly as an input, in the following analysis, some transformations will be done to make the stator voltage components v_{sd} and v_{sq}appear explicitly as inputs in both. . Assuming that the rotor flux is oriented such the quadrature component \phi _{rq}=0, the dynamic model of the induction generator. . The values of (i_{sd},i_{sq}) can be computed using the measurements of the stator currents (i_{sa},i_{sb},i_{sc}), the estimation of the stator electrical angular position \theta _s and the. . Since v_{sd} and v_{sq} given by (12) and (15) are responsible for the flux magnitude control and rotor speed control, respectively, the control goals can now be viewed as a decoupling. [pdf]
The speed control of generator is performed to control the speed of the wind turbine. For each wind speed, there is an optimum point, that is, the optimal turbine speed for which the maximum wind power is captured. The information on this operating point is known from equation (1) ( Pesic, 1994 ).
The configuration of a fixed speed wind turbine is based on a gearbox and an asynchronous generator, which is usually a squirrel cage induction generator to reduce costs (e.g. NEG Micon NM72/2000, Bonus 1300). The gearbox speeds up the rotational shaft speed from the rotor to a fixed generator speed (see Fig. 4).
An asynchronous wind turbine generator with full load dual AC-DC-AC power converter has not been widely used mainly because this configuration has not shown good performance in low wind speed. In this paper the Figure 11. Current and voltage waveform in phase a during transition. Figure 12.
Thus, the proposed stand-alone variable speed based SEIG wind energy conversion system can be used in remote and isolated areas where the mean value of the wind speed profile is relatively low. The self-excited induction generator (SEIG) has emerged from among the well known generators as a suitable candidate to be driven by wind turbine.
Two common control strategies are axial induction control and wake steering control. On the one hand, axial induction control changes the generator torque and blade pitch angle while the turbine rotor faces the wind (Figure 1).
The generator speed can be controlled at 1500 rpm with increasing loading current by increasing the capacitance of the series capacitor as shown in Fig. 7 c. Using series capacitor, the wind turbine output power can be controlled to adjust speed again.
