What is AVR in Turbo generator in Thermal power plant?

Answer Posted / d oldham

The synchronous generators used do not naturally operate at
any particular voltage but the voltage can be adjusted by
manually setting the excitation. However as soon as any
load is put on the generator a different value of
excitation is required. The AVR automatically makes the
necessary adjustment by closed loop control to keep the
generator voltage constant. The operator can manually
adjust the AVR reference to allow connection to a power
system. Once connected to a large power system the AVR
setting determines the reactive power load kVAR on the
generator. A high setting exports kVAR (lagging power
factor) and a low setting imports kVAR (leading power
factor).

A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.
