New Coils Boosts Output of Geothermal Generator (Plant Engineer)
The generator at Palinpinon geothermal power plant, in the Philippines, has been successfully rewound by Sulzer, with coil design and construction by its service center in Birmingham, England.
The site comprises two power plants, the first containing three 37.5 MWe generators and the second four 20 MWe generators – together delivering 192 MWe.
Dave Hawley, general manager for the formed coil business at the Birmingham Sulzer Service Center, explains that the project to overhaul one of the Fuji 37.5 MWe generators involved using its database combined with OEM drawings.
These enabled Sulzer to design the new coils along with wooden formers to replicate the stator, which would be used later to check the shape of the coils during manufacturing.
