I have two AC generators, the first rated 2680KVA for 380V/4345A/pf:0.7 and the second rated 3461KVA for 5500V/363A/pf:0.8. I want to parallel the two generator to a bus. The second generator passes through a transformer to down the voltage to 380V and a part of its power goes to another bus so that it's only a part of the total power of the second generator taht goes to the considered bus. I have two Basler DECS100 AVR regulator. How can I make the synchronization ? What others equipments must have ?
