Answer Posted / bhanu pratap
to understand the function of AVR first v have to understand
concept of reactive power....
all of u know reactive power..
a generator has active power and reactive power... infact
with out reactive power ther will be no generation..
reactive power is the one which is the power consumed for
the establishment of magnetic flux in the machine without
which no generation takes place....
coming to the AVR..
consider a generator supplying to the grid.. as the grid is
not purely resistive.. it generally is inductive since loads
connected to grid(consider industries)are inductive..
generator tries to draw reactive power from the grid for the
development of its magnetic flux...(under constant frequncy)
when frequncy changes ..it disturbs the magnetic flux ...so
the geneartor tries to draw more n more reactive power from
the grid.. if this happens .. rotor of the generator will
get heated due to this reactive power..
so here comes d AVR... avr produces the xtra amount of
voltage required for the machine to maintain its magnetic
fld so that (V/F) will be constant...
thats wat i feel.. inform if any corrections
when
