Answer / j benedict

With two are more parallel engine generators on line: The
generator with loss of power (rpms if isolated) would draw
power from bus. This power is reverse power and need to
remove this engine generator off of load. The loss of
power on a skid causes could be governor, fuel, ignition
that results in poor engine proformance. RPMS and torque is
real power.

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?
