Siemens - SGen-100A-4P Series - Air-Cooled Generator Brochure

siemens.com/energySiemens Air-Cooled Generators SGen-100A-4P Serieswith ratings from 25 MVA up to 70 MVAAnswers for energy.As a global technology leader in the manufacturing of electrical synchronous machines, Siemens has accumulated decades of experience in generator production and devel-opment. Our proven four-pole air-cooled generators from the SGen-100A-4P product line is the Siemens answer for turbine generators in industrial plants worldwide.Our air-cooled generators are designed using state-of- the-art methods. By utilizing special computer programs for calculation, design and production, we can optimally match the generators to the customers’ needs.123456 7896 Pole Winding Support7 Rotor Coils8 Pole Shoe9 Pole Shoe Screws1 Blower2 Exciter Current Conductor3 Journal Area4 Rotor Shaft5 CouplingFour-pole three-phase synchronous generatorOutstanding 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 ¦ long service life For every project, Siemens works closely with each customer to design a customized generator to meet their unique technical specifications, output and project needs. Using a modular building-block system, the required generator type is designed by selecting from different diameters and making adjustments to length. This enables us to supply our customers with generators tailor-made to their requirements. As an option, the gen-erator 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 excitation current 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.Industrial plants with steam and gas turbines that use SGen-100A-4P series generators are able to keep their operating costs down due to high efficiency levels of cogeneration. This ensures a considerable degree of independence from public power supply.1 Welded casing2 Stator winding and insulation are form-wound coils featuring Siemens epoxy-mica (MICALASTIC®) insulation technology (Global Vacuum Pressure Impregnation/GVPI)3 Salient-pole rotor with solid pole shoes4 Stator core5 The coolers are implemented either in TEWAC1, CACA2 or OAC3 cooling systems6 Brushless exciter set with or without Permanent Magnet Generator (PMG)7 Enclosure 8 Main Terminal BoxTechnical dataFrequency Model Power factor Apparent power Efficiency Terminal voltage50 Hz SGen5-100A-4P 0.80 to 0.90 25 MVA to 70 MVA up to 98.5 % 6.3 kV to 15.0 kV60 Hz SGen6-100A-4P 0.80 to 0.90 25 MVA to 65 MVA up to 98.5 % 6.3 kV to 13.8 kV12 3456781 TEWAC = Totally Enclosed Water-to-Air Cooling2 CACA = Closed Air-to-Air Cooling3 OAC = Open Air-Coolingsiemens.com/energyPublished by and copyright © 2013:Siemens AGEnergy SectorFreyeslebenstrasse 191058 Erlangen, GermanySiemens Energy, Inc.4400 Alafaya TrailOrlando, FL 32826-2399, USAFor more information, please contact our Customer Support Center.
