    Hi
    The problem is very general.
    You must check many characterizes in your MV network and analyze with details.
    I think you must check switchgear relay section or your breaker making current capabilities to make your generator to network.
    If you give me your email address i can send you a useful PDF about this issue to you.
    Thanks
