Performance range 370‐560 MVA
Efficiency up to 99%
Powerful generator for gas and steam applications
Our latest product innovation, the SGen-2000P series, combines air cooling with water cooling technology. Pressurized air-cooled generators are replacing indirectly hydrogen-cooled machines to significantly reduce plant complexity. They achieve efficiency and power levels comparable to indirectly hydrogen-cooled generators with ratings of up to 560 MVA. Pressurized air-cooled generators are used in simple cycle, combined cycle, and steam power plants, as well as in synchronous condensing applications.
Combining GVPI stators with water cooling technology enables uniform temperatures and low stress levels to enhance operational flexibility. The proven reliability is greater than 99.9% for more than 1,700 stator windings between 10 and 22 kV with an output of up to 650 MVA. Our fleet leader has over 150,000 operating hours and 3,320 start/stop cycles.
Modern grids require high operational flexibility because of the increased integration of renewable energy sources. Our design supports high ramp-up/down rates and frequent start/stop cycles while keeping thermal mechanical stress in the stator windings low.
Our proven MICALASTIC® insulation system and Global Vacuum Pressure Impregnation (GVPI) technology ensure maximum electrical endurance and outstanding availability.
- Insensitive to thermal cycling
- No maintenance required
- Very low mechanical stress during operation
- Non-flammable and self-extinguishing; no fire-extinguishing system needed
The absence of hydrogen gas reduces the complexity of auxiliaries as well as the cost of service and operation. There is no need for hazardous operational areas around the generator. Arriving almost fully assembled, the generator is designed for easy on-site installation and includes many provisions for accessible maintenance.
Our generators maintain a high level of common parts across the portfolio (e.g. stator core assembly and rotor). The part and component re-use improves the availability of spare parts and increases the quality in manufacturing and assembling components from our suppliers, at our factory, as well as on site.
The SGen-2000P generator offers an innovative mix of verified design features in operating ranges typically reserved for hydrogen-cooled generators. The water-cooled stator and air pressurization system allow this series of generators to operate within an extended performance range and with maximum load-shift flexibility.
The SGen-2000P implements technology featuring the latest verified design with more than 1,700 GVPI stators in operation across all operating ranges and a fleet-leading water-cooled GVPI stator with over 151,000 hours of operation and more than 3,320 start/stop cycles with no indication of thermal-mechanical stress-related issues. Without the application of hydrogen, the SGen-2000P series offers you the added benefit of unstaffed operation, e.g. for synchronous condenser applications.
The SGen-2000P generator series was designed for simplified service and maintenance. Along with eliminating hydrogen-related generator auxiliaries, various service-friendly design solutions have been implemented. Its components have been tried and tested over decades of operation, achieving a reliability rate of more than 99.9%. To minimize downtime, the maintenance intervals have been aligned with those of the prime mover and now allow for longer intervals between servicing than ever before. The rotor is designed for lifetime operation without removal for service.
Our reliable and robust generator is the result of our manufacturing and engineering design teams working in close collaboration throughout its development. By applying the latest digital technologies, our manufacturing facilities stepped up to create a world-class product for you with excellent lead times.
Our SGen-2000P series combines two proven technologies in one innovative concept. The generator operates with air up to 560 MVA and features variable pressurization with water-cooled stator windings. This enables the flexible operation demanded by today's evolving electrical grids. By eliminating hydrogen gas auxiliary systems, the SGen-2000P series' operating and maintenance costs are lower than those of traditional hydrogen-cooled products in this output class.
