Answer Posted / sunil guru
one method can b used
firstly rectify the AC to DC then with the help of DC
chopper(DC-DC converter)convert 2 required voltage then to
provide that voltage 2 gate of MOSFET OR IGBT(full DC is
given 2 MOSFET ONLY CONTROLLED VOLTAGE IS GIVEN 2 GATE OF
MOSFET OR IGBT) and thus by giving the controlled voltage
to armature speed can be controlled
AND MOST COMMON 3 METHODS R THERE TO CONTROL SPEED OF DC
MOTOR
1.ARMATURE VOLTAGE CONTROL
2.FIELD FLUX CONTROL
3.ARMATURE RESISTANCE CONTROL

in a solar power plant,we are going to step up the voltage 350V to 33kv, and to 132kv GSS. i want to ask that if it is possible that 315v/33kv is not possible because we also use 315v/11kv. or it should be 415v/33kv? is it effects generation or losses? the second question is-generation is depends on LV winding? or LV winding design for generation voltage?
