Siemens Air-Cooled Generators
SGen-100A-4P Series
with ratings from 25 MVA up to 70 MVA
SGen-100A-4P Series at Generator Plant Erfurt, Germany
As one of the international market leaders in the manufacturing of synchronous machines, Siemens has accumulated many decades of experience in the production of generators. Proven four-pole air-cooled generators, from our SGen-100A-4P series,
are the Siemens answer for turbine generators in industrial plants.
Our air-cooled generators are developed by using state-of-the-art methods. By working with special computer programs for calculation, design and production, we can optimally match the generators to the customers’ needs.
Answers for energy.
Four-pole three-phase synchronous generator
Outstanding design features of the Siemens air-cooled SGen-100A-4P series generators include:
■high efficiency,
■low noise emissions,
■low installation and commissioning costs,
■high serviceability and
■long service life.
For each customer project, a customized generator is developed according to the individual technological specifications, output and customer needs. Using a modular building-block system, the required generator type is designed by choosing from different diameters and by making adjustments to length. This
enables us to supply our customers with generators specially tailored to their requirements. As an option, the generator can also be supplied with a gearbox.
Siemens four-pole three-phase synchronous generators are used as high-voltage generators with a solid salient-pole rotor. Their rotor windings are indirectly cooled by air.
These generators use brushless excitation as a standard. The exciter power is supplied by an exciter with rotating rectifiers. The exciter is a stationary-field machine with the rotor mounted on the generator shaft. Alternatively, static excitation using slip rings is also available.
The standard design is IM 1005 featuring a frame with end shield bearings.
Industrial plants equipped with steam and gas turbines, and SGen-100A-4P series generators keep process costs down due to high efficiency levels of cogeneration. This ensures a considerable degree of independence from public power supply.
