Aiming at solving starting-up failure and simple maintenance for heavy equipment in extreme condition, a multifunction electric power platform based on ultracapacitor technology was developed. In this paper, firstly, the characteristics of ultracapacitor were introduced and starting-up faults of heavy equipment in extreme condition are analyzed. Then, the function, principle and system scheme of multifunction...
Intermittent and slow generator like PV is augmented with auxiliary device to meet the certain grid code requirements for interconnection. Ultracapacitor, battery energy storage system (BESS) or shunt capacitor at the PV terminal have recently been used as auxiliary devices for large-scale PV generator system to improve the system performance during transients. Although the studies on individual auxiliary...
In this paper, hybridization of a BB460000 locomotive is proposed integrating a reduced power diesel generator, batteries and ultracapacitors as storage elements. The power mission of the BB460000 locomotive is studied in order to analyze its ability to be hybridized and to identify the most critical mission. An energy management strategy based on a frequency sharing is proposed. It allows strongly...
