1. Yes ships do have generators. Using AVR's and controlling
prime movers speed, voltage and frequency are achieved.
2. Only one difference b/w our system and those in Ships is
they have unearthed system. Here phase voltage is the
voltage b/w phase and neutral OR earth. Since ships are
unearthed phase voltage is b/w phase and neutral.
