Recommended practice for emergency power systems in health care facilities
Chapter V of the White Book deals with the requirements and equipment which are recommended for health care facility emergency power systems and their operation. Suggested methods for system design, installation, testing, and maintenance are included. The main components of the emergency power system are the generator sets, automatic transfer switches, engine generator controls, engine cranking batteries, and battery charger. Additional equipment may include synchronizing and paralleling equipment for multigenerator set installations, utility peak demand reduction controls, elevator emergency power selector systems, and bypass-isolation switches for automatic transfer switches.
An analytical look at standby diesel engine/generator loading
Diesel engine/generators are complex systems which utilize different governors, voltage regulators, excitation systems, excitation support systems, and turbochargers. Even the engine and the generator have widely varying characteristics and ratings and are often matched differently for different applications. In sizing and specifying these units, the engineer should use `rules of thumb' cautiously. As many known factors as possible should be applied to the sizing and specifying process. In the future, the computer will probably be used routinely to predict diesel engine/generator response to dynamic loads.
Modem AC Generator Control Systems: Some Plain and Painless Facts
The nomenclature, hardware operating principles, and performance considerations that influence the application and selection of modern generator control systems are reviewed. Certain critical but frequently misunderstood terms are identified and defined. Basic exciter, regulator, and governor systems are briefly described and compared. While generally applicable to control systems for generators of all sizes, most of the information is pertinent to installations involving small to medium (industrial size) diesel, steam, and gas turbine driven units.
