Hybrid power sources with energetic buffer technology are based on supercapacitors with bi-directional dc-dc converters. This paper describes the application of bi-directional converters with Supercapacitors for remote area power hybrid sources using photovoltaic sources, Diesel Generator Sets and battery storage. One of the future trends in that area of power sources supercapacitors are introduced...
The engine-generator dynamics at a sudden load change (from low load to high load) remains a challenge in case of variable speed diesel generator. The dynamic behavior analysis presented here proves that the introduction of an energy storage element into the EGS with variable-engine-speed concept eliminates this drawback. This paper addresses the identification of the dynamic behaviour of such variable-speed...
This paper brings some practical results of research devoted to the new generation of mobile electrical power sources, based on the VSCF technology (variable speed-constant frequency). In this generation of mobile electrical power sources the driving motor and generator speed is optimally controlled in accordance with the load power thus decreasing the fuel consumption. The output voltage and frequency...
New generation of mobile electrical power sources is based on the historical change from constant speed, determining the required frequency, to the optimally changed engine and generator speed. The constant frequency and required voltage value is achieved by means of power electronics voltage and frequency converter. The paper brings some new analyses of efficiency investigations of mobile power sources...
