    Load Sharing and Parralling

    We have 4 x 500KW generators. Each 500kw.
    Genset A and B are working well whilst suddenly these few days , Genset C & D just do not
    behave themselve. These 4 genset are in island mode and syn among themselve. These are natural gas engine.
    When we run A and B,, no issue was there, but whenever any one of the genset either C or D when parrallel into
    the common bus.. it will take load with the other units but only up to 150 KWe ,, Genset C will go into reverse
    power but the Genset A or B have no issue but pick up all the power and Genset C breaker will open.,
    These is the same as Genset D. It will behave the same as Genset C.

    What i like to know if the neutral line an issue?

    Well, I would start by measuring stuff rather than beginning the resolution process on a guess.
