Recommend with justification the generators used in SWT.
1. Fixed Speed Induction Generator: This is squirrel cage induction generator for fixed speed. This is 1) reliable 2) self-starting 3) easy to adjust 4) have low maintenance.
2. Permanent Magnet Synchronous Generator: This is synchronous generator for variable speed. This is 1) eliminate field copper loss 2) high power density 3) low rotor inertia 4) high efficiency 5) optimizes use of given grid capacities 6) Better cooling performance 7) Reduced noise level of moving parts.
