PROJECT TITLE :

Temperature-dependant voltage regulator operation for optimal load acceptance of a diesel generator

ABSTRACT :

Standby diesel generator sets (gen-sets) are used worldwide to provide a backup electricity offer ought to the mains supply to a web site be lost. The diesel engine can start rapidly and therefore the gen-set will begin supplying power inside 20??sixty s. Ancient commissioning of a gen-set is performed when the engine is at its normal `hot?? operating temperature. Unless a jacket water heater is used, once the gen-set is shutdown the engine will cool to the ambient temperature, and following start-up the load acceptance performance will be less than when it was during a hot operating condition. A unique voltage regulator design which utilises engine temperature as a supplementary management input is presented, providing an improvement in a very gen-set??s cold load acceptance performance without compromising its customary hot performance. The new voltage regulator style is tested on a commercial diesel gen-set to demonstrate the optimised load acceptance performance.
