Is it true that the faster the propeller turns on a wind turbine the more electricity it makes?

No, in fact if the wind is strong enough, wind turbines can take power from the grid to help slow the blades down. Modern wind turbines have constant speed blades on them which vary the power to the hub for a given wind speed and keep the blade speed constant. Thus more power may happen at the same blade speed as low wind situations. Often higher blade speeds indicate that the turbine is in idle mode and not producing any power for the grid. Power is cubed so the power available is dependent on the wind solely. A 28 MPH steady wind will allow production of power at 100%. If the wind goes much above this speed, a shut down occurs. If the wind is at 14 mph, the power available is 10% of rated. Speeds of wind systems on the grid should be fairly constant. despite power setting.


What is cpp and ipp power plant?

A CPP is a captive power plant, a power plant that supplies large amounts of power outside its grid. A IPP is an independent power plant that supplies to only its grid.


What is the job of a dynamo in the national grid?

The national grid is a means of distributing electricity, there is no need for a dynamo (which produces electricity) in the national grid. However, dynamos (generators) are needed in the power stations.

How do energy get to homes?

Energy gets from the power plant to customers via the power grid (high voltage power lines).Transmission lines that generally operate at high voltages are responsible for long distance delivery of electricity. Substations step the voltage down to deliver it locally, and Transformers further step down the voltage to deliver it to the customer.Note: There are no energy transformations invloved in this process. The power plant (whatever kind it might be) produces electricity (electromagnetic energy), and this is delivered to a user via the power grid. For energy transformation in power plants, refer to those specific questions.

How frequency is controlled in a grid?

The frequency is determined by the operational speed of the generators in the power plant and is very closely related to the RPM of the generators (it might only differ in a constant multiplier).Depending on the load of the grid a proper torque must be applied on the generators to generate voltage with the proper frequency. Once the AC is out in the grid its frequency is much less prone to environmental effects than its voltage.


What is the most important of the turbine used in a power station?

Keeping the speed constant is vital if the turbine is to deliver power synchronised with other turbines supplying the 'grid'. If it remains 'on line 'and 'out of phase ' with the 50/60 Hz AC frequency of the grid it will be destroyed.


Why steam turbine speed is kept constant in power plants?

Well, the steam turbbine is most likely connected to an A/C generator which gives off the same frequency as the grid, so by running the turbine on a fixed frequency you don't have to condition the electricity before it can be released onto the grid.


How is grid frequency and power plant output frequency matched?

contrary to the belief that the 50-60 Hz is stable in reality it is not frequency changes constantly during the day as power is increased or reduced but the average for a day is pretty much constant. a generating plant is a thermal or hydro machine it cannot responds very fast. so the average is stable for the grid since all plants have reserve spin power available constantly


Why does the synchroscope need to be rotating clockwise if it is turning slowly counterclockwise won't that work the same?

because the incoming generator has be connected as a source and not a load to the grid. if the frequency of the incoming generator is lower than the grid frequency then ... it will behave as a motor drawing power from the grid and generator will trip in reverse power protection.


Can an amplifier imported from US be used in Australia?

yes it can be used because power grid frequency is same


How can you sychronise your generater to the power grid?

The short answer is: It's illegal. Almost universally, the power grid is the property of the power company, and is regulated by the utility. It is illegal to connect a generating device to the power grid without the express approval of the utility. It is highly unlikely that anyone needing to lookup the answer here could ever attain such approval. Any installations that are approved for power grid connection are connected by qualified electricians that have been certified for the connection of generating equipment by the utility. To answer the more general question of how generators become synchronized, small generators are basically forced into synchronization by the large generators on the grid. All generators connected to the same grid also utilize throttling devices to adjust their frequency and phase to properly match the grid, so that they are not a constant strain on the grid. Large generators are synced before being connected to the grid.

What do you mean by turbine synchronization?

During a typical power plant startup, all components of the power plant are started slowly. The turbine is first rolled at a slow rpm. Then the rpm is increased gradually to a point where it can match the frequency of the grid. At this point, the turbine can be synchronized with the grid and start outputting electricity into the grid.


What is the industrial frequency?

Industrial frequency, as used in Communications, aka the ISM band, is the frequency of signals between 900Mhz to around 2.4Ghz of encoded, compressed, or analog signals... industrial frequency can also refer to the common local power grid frequency (usually 60 or 50 Hz)
