IEEE Recommended Practice for Functional and Performance Characteristics of Control Systems for Steam Turbine-Generator Units
Revision Standard - Inactive-Withdrawn.
Minimum functional and performance characteristics related to speed/load-control systems for steam turbine-generator units that may be interconnected on a power system are recommended.
The recommendations apply to the following types of steam turbines, rated at 500 kW and larger, intended to drive electric generators at constant speed without initial steam-pressure control, exhaust steam-pressure control, or either:
Emergency governors, other overspeed control devices, and, in general, devices that are not responsive to speed, are not covered.
These recommendations apply to the following types of steam turbines, rated at 500 kW and larger, intended to drive electric generators at constant speed:
Condensing or noncondensing turbines without initial steam-pressure control, exhaust steam-pressure control, or either, including turbines used with reheat, regenerative feedwater heaters, or both. (See Figs 1 and 2).
Condensing or noncondensing turbines with initial steam-pressure control, exhaust steam-pressure control, or both, including turbines used with reheat, regenerative feedwater heaters, or both. (See Figs 3, 7, 8(a), and 8(b)).
Automatic extraction, induction, or both, and mixed-pressure turbines. (See Figs 4, 5, and 8(c)).
The purpose of this recommended practice is to recommend functional and performance characteristics related to speed/load-control systems for steam turbine-generator units that may be interconnected on a power system,
such that this recommended practice may be included in prime-mover purchase specifications.
