How is grid frequency and power plant output frequency matched?
Kpmore
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

What happens to the output in terms of real power of a generator when you change the voltage and frequency say from 220v 50Hz to 110v 60Hz?
The voltage and frequency ARE the output of the generator. If you change the fuel to the generator, it will change speed, and the voltage will change. Less fuel = less speed = lower frequency = lower voltage.
What is output frequency sync to mains?
this always used in inverters and UPS As in standby UPS And line interactive UPS ,the output frequency must be always track the input frequency as it supply the load from utility in standby mode, for any change that will affect the load . as example the frequency of the utility was with permitted values say 58Hz and suddenly the main power cutout, so UPS must be on same frequency so when convert to backup stored power mode ,the load doesn't affected and power continue to supply the load from the batterys through inverter , so output frequency must be always synchronized to utility frequency (mains) in case of any fault happened, hope i answered your question.

Does the input and output frequency of the transformer is the same?
For an 'ideal' transformer operating at full load, the answer is yes. But, 'real' transformers are a little less than 100% efficient so, in practice, the input power will slightly exceed the output power. In most circumstances, for the purpose of calculating primary and secondary currents, we can assume 100% efficiency.
Frequency to power?
THERE ARE NO FREQUENCY TO POWER CONVERSION rephrase the question
What is the Difference between frequency converter and frequency inverter?
frequency is genrally cycle per second, and frequencies may be of a dc nature or ac , devices which convert dc frequency in to an ac frequency are frequency converters and devieces which convert ac frequency in to dc frequency are frequency inverters. because in terms of power electronics, devices which convert ac to dc are called converters, and devices which convert dc in to ac are called "inverters" 'mehboob hunzai" I'm a engineers in this devices, the frequency inverter is convert AC to AC but with variable frequency output, means the frequency & voltage are adjustable; The frequency converter can convert DC to AC, like 24VDC to 220VAC and also the frequency is adjustable. One most important thing is the out power of frequency inverter just can be used for controlling AC motor, while frequency converter can be treated as normal power supply as our daily using power grid.

What difference between RF power output watt and electrical power output watt?
The difference is in the output frequency.
What is the power output of ameren's nuclear plant?
Ameren? Where is that plant located?
Another way of saying that the output is 70 percent of the signal input at cutoff frequency is that the output is up or down dB at frequency cutoff?
If the output power is 70% of the input power, then the output is roughly 1.55 dB downcompared to the input.If the voltage at any point of the output waveform is 70% of the voltage at the same pointon the input waveform, and the input and output impedance are equal, then the output is3.1 dB down (rounded) compared to the input.
What is the output of transmitter?
The output of a radio transmitter is ac power at a radio frequency, designed to run into a load with a specified resistance, often 50 ohms.
Why cut off frequency is called half power frequency?
Cut off frequency is that frequency at which the power output of the circuit reduces to half of its power in pass band. Power (P)= Current2 X Resistance. so to reduce the power by half we need to reduce the current by 1/sqrt{2} = 0.707 = 3 db. So it's also called half power frequency. http://enter4joy.com

Definition of half-power frequency?
The frequency on an amplifier response curve which is greater than the frequency for peak response and at which the output voltage is 1/√2 (that is, 0.707) of its midband or other reference value.
Which filter do you use to remove pulsations from a power supply output?
There is no answer to this. If a power supply pulsates, what frequency, etc. If a power output needs filtering there are oodles of ways to do it depending on the desired result and the starting conditions. A starting point is a big capacitor.
Million units in thermal power plant?
B. T. U.Answer:With the exception of the USA power plant output is measured in Megawatt/hours (Mega=million)
What happens to the output in terms of real power of a generator when you change the voltage and frequency say from 220v 50Hz to 110v 60Hz?
The voltage and frequency ARE the output of the generator. If you change the fuel to the generator, it will change speed, and the voltage will change. Less fuel = less speed = lower frequency = lower voltage.
Do power plants make their own power?
Yes, in a power plant a proportion of the generator output is fed back into the plant to run auxiliaries, before the bulk output is transformed up to the high voltage of the main transmission lines. In a nuclear plant some backup power is essential in the event of losing the connection to the outside completely, and this is provided by diesels with their own generators.
Linear Algebra applications?
linear algebra has a no. of applications like in any power plant you put all the variables things in linear equations and change them according to your required output of power plant which is surely be the voltages and currents following in the output circuit.
