SGen-3000W generator series
High-power generator with proven water/ hydrogen cooling technology
Performance range 540‐1,300 MVA
Efficiency up to 99%
Reliable generator for high-power applications
Outstanding performance for large gas and steam power plant applications
Our latest water-/hydrogen-cooled generators benefit from proven design and technologies as well as the application of our building-block approach. They share many features with other products across our portfolio. This allows us to optimize material selection and performance to provide you with a low-cost, highly efficient, and easily maintained generator for high-power applications.
Highlights of the SGen-3000W generator series
Modern grids require high operational flexibility because of the increased integration of renewable energy sources. Our design supports high ramp-up/down rates, frequent start/stops while maintaining low thermal mechanical stress in the stator windings.
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
Combining GVPI stators with water cooling 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 1,300 MVA. Our fleet leader has over 150,000 operating hours and 3,320 start/stop cycles.
Our generators display a high level of common parts across the portfolio (e.g. stator core assembly and rotor). The reusing of parts and components improves the availability of spare parts and increases the quality in manufacturing and assembly at our factory as well as on site.
- Generator technology
- Service and maintenance
- State-of-the-art manufacturing
- Tailor-made for today's flexible operating environment
The SGen-3000W 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 150,000 hours of operation and more than 3,320 start/stop cycles with no indication of thermal-mechanical stress-related issues. Hydrogen cooling with water-cooled stator bars makes this generator series ideal for any operating regime.
Service and maintenance
The SGen-3000W 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 latest digital technologies, our manufacturing facilities stepped up to create a world-class product for you with excellent lead times.
Tailor-made for today's flexible operating environment
The SGen-3000W series utilizes proven technology with endurance verified in the field showing it can withstand the rigorous operating conditions of electrical grids impacted by the increasing integration of renewable energy sources.
