Variable rotor-resistance control of wind turbine generators

By adding a variable external resistance to the rotor of an induction generator used in a wind turbine, it is possible to manipulate the torque-speed curve and control the output power. The hardware implementation is accomplished by a set of three-phase external resistors connected in series with the rotor windings. To vary the effective value of the external resistance, a three

Gravity foundation

The design of this solution consists of a slab foundation for a steel or a concrete tower. It is the most common form of a foundation for wind turbines but yet remains a complex structure.

Trainz Engine Editor | Trainz

Theoretically, notch 1 provides one eighth of the engine/generator power to the traction motors. Since Tractive effort (TE) = Power divided by Speed, a constant level of power provides exponentially decreasing TE as the speed increases. Speed will increase until the TE = the rolling resistance of the engine (or consist).

Simplified Formulae Method for Estimating Wind Turbine Generators

This paper aims to extract simple formulae for estimating the ground resistance values of wind turbines (WT) installed at terrains that can be modeled by a two-layer soil structure. Several grounding system configurations, applied in construction practice, were used as case studies. Various combinations of soil resistivity values for the upper and the lower layer of a

How to Fix Honda EU2000i ECO Throttle Issues

The best time to turn the ECO throttle on is when the generator has been on and warmed up, which is usually after 2 or 3 minutes. Then the next best time to turn the ECO throttle on is after you have started your appliances.

6 FAQs about [Where are the generator throttle and wind resistance ]

How to control the rotational speed of a wind turbine generator?

There are three common methods for controlling the rotational speed of a wind turbine generator. (1), mechanically spilling wind from the blades by changing their pitch angle. (2), use a mechanical brake to stop the turbines rotation at high speeds. Or (3), use some kind of electrical load in the form of a dump load to act as an electrical brake.

Why does a wind turbine generator spin at high speeds?

As an electrically connected load keeps the wind turbine generator within its designed operating range. If a wind turbine generator, (WTG) is allowed to rotate in the wind with the batteries disconnected, it will start spinning at very high speeds because it is operating without any connected load to act as an electrical brake.

How does a wind turbine gearbox work?

The gearbox converts the turning speed of the blades 15 to 20 rotations per minute for a large, one-megawatt turbine into the faster 1,800 revolutions per minute that the generator needs to generate electricity. A gearbox is typically used in a wind turbine to increase rotational speed from a low-speed rotor to a higher speed electrical generator.

Does a wind turbine generator need a controller?

Wind is unpredictable and constantly changing, therefore the electrical output from a wind turbine generator will be a variable voltage and variable frequency (AC types) so the use of a controller for high wind speed protection makes sense.

What happens if a wind turbine generator is not connected?

If a wind turbine generator, (WTG) is allowed to rotate in the wind with the batteries disconnected, it will start spinning at very high speeds because it is operating without any connected load to act as an electrical brake. This overspeed condition can cause mechanical damage to the turbine as it could potentially self destruct.

How do type 2 wind turbines work?

While largely relying on the same concepts as fixed-speed wind turbines at lower-than-rated wind speeds, they typically incorporate blade pitch and output power controls to optimize power extraction at higher-than-rated wind speeds. The Type-2 turbines use rotor resistance control to achieve output power control.
