SGen-1000A generator series

Our air-cooled generator series offers you a competitive advantage by providing ratings of up to 370 MVA with operationally proven technology. We continuously improve our generators and focus on increased reliability, improved serviceability, high efficiency, and optimum plant integration. Our generator designs benefit from more than 150 years of engineering experience going back to the invention of the electrical generator by Werner von Siemens in 1866.

Remote Diagnostic Service

Remote Diagnostic Service (RDS) help you to optimize your asset production by turning data into value. In a proactive approach, we monitor the complete range of oil and gas, and industrial rotating equipment in more than 80 countries to identify a potential problem before it impacts operation. We aim to maximize the availability and reliability of our customers' installed base.

Technology overview

Our generators are designed using our building-block system with optimized diameter and length sizing to achieve perfect alignment with your plant and the grid requirements. Grid studies can be performed. Many more options are available including variants of the cooling system and the position of the generator leads. All parts and connections are readily accessible and the enclosure can be easily removed for installation or maintenance.

Air-cooled generators fit to most steam and gas turbines on the market

Flexible gas and steam power plants will remain a key component of a demand-driven power supply. They form the solid foundation of a diverse and clean energy mix – indispensable for meeting the world's current and future challenges. Our air-cooled generators complement the turbine packages of any manufacturer and meet grid and environmental requirements as well as specific customer needs.

Replacement of older, high-maintenance generators

With our Footprint™ generator concept we offer solutions to replace older, high-maintenance water-, hydrogen- or air-cooled generators with state-of-the-art SGen-100A-2P generators. The modular design of our generators can be adapted to match existing foundations and plant interfaces to minimize reconstruction costs and installation time. This can be a time- and cost-effective alternative to repairing an existing generator.

Technical benefits

Available for various types of power plants, our generators can be efficiently adapted to local site conditions.
In addition, they can increase the rated power and efficiency of a power plant.
By replacing the older equipment, you also reduce the risk of finding unexpected signs of aging or damage in the existing generator.
For the replacement of non-OEM equipment, 3D measurement is available to adapt existing foundations.

Transmission grid stabilization

Rotating synchronous condensers are a proven, reliable solution for ancillary grid services guaranteeing frequency and voltage stability, plus the ability to ride through grid disturbances. Today’s emerging power systems are dominated by converter connected renewable power producers which are susceptible to decreased short circuit power and system inertia, making them more sensitive to electrical faults and sudden load imbalances. Rotating synchronous condensers are significantly less sensitive to these issues.

Grid benefits

Synchronous condensers have the unique ability to respond inherently without any time delay to fault or load imbalance events. They increase the short circuit power by their overload capability and improve the rate of change of frequency (RoCoF) by the physical inertia contribution. Furthermore synchronous condensers provide dynamic voltage control by supplying and absorbing reactive power to and from the grid.

Synchronous condensers

A synchronous condenser solution comprises a generator connected to the high voltage network through a transformer. It is started by either an electric motor or a static frequency converter. Once synchronized with the network, the generator behaves like a synchronous motor without load, compensating reactive power and stabilizing the system, in case of a fault or imbalance events.
