All design work is controlled by a disciplined Product Development Process
Specific reviews must be passed at ends of defined development steps. Examples include:
Create and review Product Requirements Specification (market requirements and conceptual features)Create and review Product Design Specification(basic technical design features and commercial boundaries)Create and review Basic Design, (major components and the entire generator assemblyDesign components and hold Final Design Reviews
With this Product Development Process, Siemens ensures that the generators meet market requirements and customer expectations for reliable operation during their lifetime.

Siemens Has Designed and Built Giga-watt Class 4-pole and 2-pole Turbine Generators
4-pole: 50 Hz ≥ 2222 MVA, 60 Hz ≥ 1520 MVA
2-pole: 50 Hz ≥ 1300 MVA, 60 Hz ≥ 1200 MVA
2222 MVA 50 Hz 4-pole generator is most recent step
Next step is to develop 2-pole generators ≥ 1500 MVA based upon proven design features and market feedback
Without leaving the range of experience, the capabilities of these designs have been achieved by slight increases in dimensions of active length and diameters and also slight increases in utilization
These designs are evolutionary, not revolutionary
Page 24 Generators E F PR GNMontgomery/Sedlazeck27 August 2008Confidential / © Siemens AG All rights reserved
In the most modern of these generator designs the major features include the following:
Stators designed for railway transport by Schnabel car
Stator cores with axial ventilation and “flux trap” core ends
Water-cooled stator windings with anticorrosion features (copper and stainless steel hollow conductors) and robust and reliable electrical and mechanical end turn connections
Hydrogen-cooled rotor windings with axial cooling
High pressure blower mounted on turbine side of rotor
Page 25 Generators E F PR GNMontgomery/Sedlazeck27 August 2008Confidential / © Siemens AG All rights reserved
All features in current Siemens generator designs are based upon:
Features that have exhibited good service experience for decades in the Siemens generator fleet
Design analyses based in first principles and calibrated by tests
Component testing
Manufacturing process qualification
Independent design reviews
Assembled generator factory testing

Considerations of grid stability
Stable operation of a grid is less influenced by generator design with respect to reactances and short circuit ratio but more influenced by:
Stiffness and structure of the grid
Sufficiently dimensioned high voltage lines
Sophisticated generator voltage regulator
