Improvement and Optimization Configuration of Inland Ship Power and Propulsion System

Advances in power and propulsion energy management improvements can significantly contribute to reducing emissions. The International Maritime Organization (IMO) Marpol regulations impose increasingly stringent restrictions on ship’s emission. According the measured data of target ship typical working profiles, fluctuation, fuel consumption emission are analyzed, result represented that there serious pollution problems diesel engine system. Based ship-engine propeller matching design theory, model was built, new system obtained by simulation. From perspectives power, economy green, performance indexes LNG compared cost advantage, green advantage disadvantage with determined. By comparing topological structures different hybrid forms, form is improved be gas-electric based ESS (Energy Storage System), selection supercapacitors lithium batteries compared. low-pass filter strategy, distribution ultracapacitor battery distributed. In order determine optimal configuration, a capacity configuration investment cost, storage life as objective functions established. NGSA-II algorithm used calculate scheme completed decision model. this case, reduces pollutant emissions, it also daily costs 38% shows we complete recovery 1.28 years.
