about diesel-generator voltage control
(OP)
hello, ı wanna ask you about the relation between diesel-generator automatic voltage control and compensation, for example we have a d.g and a mains and we feed the loads from mains and cos fi= 0,75 and we have no compensation system, at that point the mains is gone and we transfer the power onto the diselgenerator, so if we have a AVR on the dieselgen what will be our cos fi on the final situation?(I wonder if AVR makes a compensation??)

by the way excuse me i confused the this situation with the one in which a generator connected to the infinite bus can make compensation if works as motor (synchron machine)...
RE: about diesel-generator voltage control
The isolated generator is not compensating or correcting. It must provide the reactive power requirements of the load. The loads draw current and the generator provides it. If some type of power factor correction is added, the generator will not have to provide as much reactive, which might allow it to provide more real power.
The generator can only provide up to its rated current, regardless of the power factor of the load. (Actually, it's a bit more complicated - it is based on the generator capability curve.)
