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.

It’s no news that generators emit high levels of carbon monoxide. This is a known gas which is very dangerous to our health and safety. In fact, there have been several incidents andreports in the pastthat confirms how hazardous this gas is. Many homeowners have been hospitalized, while some have lost their lives. . As I mentioned earlier, there are two ways to vent a generator in a garage Option 1: Connect the generator’s exhaust to a long flexible tube Option 2: Connect the exhaust to a fixed PVC. . As I mentioned earlier, Option 2 involves a little bit of work compared to option 1. but if you are handy with tools, this will be an easy project. Essentially, we will use PVC pipes to make an air vent. . As I mentioned earlier, Option 1 is much simpler, and many homeowners will prefer that option. Option 2 is challenging and involves a bit of work. However, the outcome is rewarding.. . Suppose you were able to follow these steps to vent your generator, congratulations. Here are two recommendations that will. [pdf]
Venting out the generator exhaust will keep clean and toxic-free air inside your home. You can attach an exhaust extension to direct the exhaust gases outside the house. The extension installation will require a flexible, durable, and heat-resistant tube or pipe. You must also create a hole in the wall where the extension passes through.
Installation: You can install an exhaust kit to direct generator emissions outside through a wall or window. Secure Attachment: Ensure the kit is securely attached to the generator’s exhaust outlet and the exterior wall. Seal Gaps: Seal gaps around the exhaust pipe to prevent exhaust gases from infiltrating your living space.
The exhaust from your generator should not vent inside your home. It is critical to redirect the exhaust because toxic gases can be harmful to you and your family's health. To keep you safe and breathe clean air inside your home, you can learn from this post how to vent your generator exhaust outside.
There are two ways to vent a generator in a garage. The first option is to connect the generator’s exhaust to a long flexible exhaust tube and route it to a well-ventilated area. The second option is to connect the generator’s exhaust to a PVC vent pipe outside that discharges the fumes into the atmosphere.
Generator’s exhaust kits are valuable tools for safely and efficiently managing exhaust gases. These kits typically consist of flexible pipes, fittings, and clamps for straightforward installation. Installation: You can install an exhaust kit to direct generator emissions outside through a wall or window.
Airflow is vital to running well. To ensure your generator is working well, it needs to have airflow in two places: Both sides need to be open and allow the generator to pass air through well. When installing an exhaust extension, you should use the same size tubing that your generator’s exhaust uses.

Each gen set must be equipped with its own exhaust system. Ganging or sharing exhaust piping increases chances of fumes entering idle engines or equipment, subjecting them to corrosive gases. Specify Schedule 40 piping. Its heavy duty construction dampens vibration and resists corrosion from condensate.. . Mufflers, when installed as close to the engine as possible, offer best sound attenuation and minimize pipe vibration. Like piping, mufflers should be installed in a slant and equipped with. . Pipe should be installed with at least 229mm (9 inch) clearance from combustible materials. High temperature insulation or prefabricated insulating sections can be used over. [pdf]
