Generators SGen-1000A- Brochure

Answers for energy.Siemens Air-Cooled Generators SGen-1000A Serieswith ratings from 165 MVA up to 350 MVASGen5-1000A at Simmering Power Plant near Vienna, AustriaSiemens offers in its Siemens Generator (SGen™) product line advanced air-cooled, two-pole generators, called SGen-1000A series, with ratings between 165 and 350 MVA for steam and gas turbines. This generator product line brings together all of the experience gained in the manufac-turing of more than 9,000 generators over the past 100 years, with a combined total of more than 700 GW of installed capacity.2Air-Cooled Generators1 The complete stator core and winding assembly is Global Vacuum Pressure Impregnated (GVPI) with an epoxy-mica (MICALASTIC®) insulation system that provides uniform electrical insulation and added mechanical strength2 The radially direct cooled stator core provides maximum heat transfer capability for the stator winding with minimum flow resistance for the overall cooling circuit3 Radial path rotor cooling with flow path that provides a uniform flow and temperature distri-bution and reduces field current requirements4 Symmetrical ventilation system uses two low-pressure air blowers in conjunction with a multi-zone stator cooling construction172894565 The aluminium "high-efficiency endplate" acts as both a mechanical pressure plate for the lam-inated stator core and a shield for the magnetic field. The design of the generator makes use of materials that reduce eddy-current losses in the area of the pressure plate6 The RIGI-FLEX® end-winding support system has been in successful operation since the 1980s. This well-proven bracing system provides rigidity to withstand transient fault loads combined with flexibility to withstand normal operation cyclic thermal expansion and contraction, which occurs during startups and load changes7 The stator core is flexibly supported in the outer casing by spring assemblies. This prevents vibration at double rotational frequency from impacting the outer casing and thus the foun-dation tabletop8 The use of multiple cooling zones in the active part of the generator yields a more uniform temperature profile9 Collector housing for static excitation system.

This means that customers who choose air-cooled generators benefit from the manu facturing and operational advances made with respect to hydrogen-cooled generators.A design requiring low maintenance in connec-tion with our worldwide service network guaran-tees the highest availability.3Coolant Air-, OAC (Open Air-Cooled) or TEWAC (Totally Enclosed Water to Air-Cooled)Design In accordance with IEC and ANSI standardsThermal classification Class F insulation systemType of enclosure Suitable for outdoor and indoor installationExcitation Static or brushlessTransport dimensions Suitable for rail transport in most countriesSimering 1, Austria Combined-cycle power plantPerformanceNet plant output: 894 MWGenerator Type: SGen5-1000AApparent Power: 315 MVAJebel Ali L2, UAE Combined-cycle power plantPerformanceNet plant output: 410 MWGenerator Type: SGen5-1000AApparent Power: 256 MVAAmbarli, Turkey Combined-cycle power plantPerformanceNet plant output: 560 MWGenerator Type: SGen5-1000AApparent Power: 350 MVAFor more information please contactyour local Siemens sales representative.SGen-1000A Series Air-Cooled Generators: Referenceswww.siemens.com/energyPublished by and copyright © 2012:Siemens AGEnergy SectorFreyeslebenstrasse 191058 Erlangen, GermanySiemens Energy, Inc.4400 Alafaya TrailOrlando, FL 32826-2399, USAFor more information, please contact our Customer Support Center.
