I am working in an older hydroelectric powerhouse. Original generators had two sections, one at 800KW @4160V, the other at 1MW 250VDC. Exclusively powered an industrial plant. In '70s DC was removed, and AC section was rewound for 1.5KW @4160V. River is tidal at this location, and at low tide we have to limit power generation to prevent overheating the windings. We are looking for someway to extract the additional power available from the turbine, be it a DC winding or an additional AC winding. Some schemes may require a motor/generator set to convert to normal mains power (hard to get two AC windings on the same shaft syncronized).
