In summary, governing in wind mills is executed by using a flywheel and clutch mechanism to ensure the generator's shaft rotates at a constant speed, similar to how it is done in hydroturbines by regulating water flowrate. This engineering trick allows the flywheel to store potential energy and maintain a given frequency, even if the turbine's speed is lower for a period of time. Alternatively, some wind turbines may vary the pitch of the blades to achieve the desired speed, as a clutch would waste energy.

I want to know that how is govering is executed in case of wind mill to ensure that generator's shaft rotates at constant speed so as to generate electricity at fixed frequncy. Like in case of hydroturbine, governing is done by regulating water flowrate.

I don't know if this is case in Wind Turbines, but I know in some generators that a flywheel and clutch mechanism is used to regulate rotational speed. The flywheel stores potential energy from the spinning turbine (or motor in the case of the generator) on which a clutch is installed so that the motor cannot spin the flywheel faster than a given speed. The flywheel in turn can continue to rotate at a given frequency even if the speed of the turbine is lower than needed for a given period of time based on its mass. Like I said, this may not be the case here, but it is a engineering trick used in generators.

Do they not just vary the pitch of the blades? A clutch would waste energy.
 

1. What is the purpose of governing in case of wind mill?

The purpose of governing in case of wind mill is to regulate the speed and power output of the wind turbine in order to maintain a stable and efficient operation. This helps to prevent damage to the turbine and ensures that it is operating at its optimal capacity.

2. How does governing in case of wind mill work?

Governing in case of wind mill involves using control systems to adjust the angle of the turbine blades or the speed of the rotor in response to changes in wind speed or power demand. This is typically achieved through the use of sensors and actuators that communicate with a central controller to make adjustments as needed.

3. What are the different types of governing systems used in wind mills?

There are two main types of governing systems used in wind mills: passive and active. Passive systems rely on mechanical components, such as springs and weights, to adjust the turbine's angle or speed. Active systems use electronic components and sensors to make more precise adjustments and can also incorporate advanced control algorithms.

4. How important is governing in case of wind mill for overall wind energy production?

Governing is essential for the efficient and safe operation of wind mills. Without proper governing, turbines may overspeed or operate at suboptimal speeds, leading to decreased energy production, increased wear and tear, and potential damage to the turbine.

5. What are some common challenges faced in governing wind mills?

One common challenge is accurately predicting and responding to changes in wind speed and direction. This requires sophisticated control algorithms and sensors. Other challenges include maintaining the balance between power demand and wind turbine output, as well as dealing with mechanical issues and maintenance requirements.
