The high power, rapid transients, and harsh environment expected to be imposed on both the electrical and thermal systems may well be unique to this class of ship. In order to develop the thermal analysis, a comprehensive visualization tool to display the temperature and heat dissipation distributions in the entire ship has been developed. This tool includes a simplified physical model, which combines principles of classical thermodynamics and heat transfer, resulting in a system of three-dimensional differential equations which are discretized in space using a three-dimensional cell centered finite volume scheme. Therefore, the combination of the proposed simplified physical model with the adopted finite volume scheme for the numerical discretization of the differential equations is called a volume element model (VEM). In this work, a 3D simulation is performed in order to determine the temperature distribution inside the ship for six different operating conditions. Visit visualization tool is used to plot the results.","PeriodicalId":446953,"journal":{"name":"2009 IEEE Electric Ship Technologies Symposium","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115486802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inverter topology most suited for the expansion of the hybrid electric drive is the VSI inverter because this topology allows a DC/DC converter to control the power flow between the battery and the DC-bus of the propulsion motor. Different battery technologies are discussed by comparing the specifications of a 1 MWh reference battery. The impact of the addition of the batteries on the propulsion system is discussed. The battery allows the diesel generators to operate closer to their optimal efficiency by charging the battery when load is below optimal and by discharging the battery when load is above optimal. During anchoring, harbour docking, maneuvering and low speed cruising, the required power drops significantly and battery can take over from the diesel generators. The limited all-electric range allows the ship to shut off its engines some tens of km away from the harbour, improving local air quality. A large capacity battery can also improve safety by offering a few hours of all-electric low-speed cruising. In naval applications the all-electric range improves the stealth capabilities of the ship by reducing its acoustic and thermal signature. In the CODLAG configuration top speeds can be achieved with less prime movers by installing larger electric motors that are fed from both normal generators as well as the battery.","PeriodicalId":446953,"journal":{"name":"2009 IEEE Electric Ship Technologies Symposium","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131797925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Simulation of the full circuit models shows that the planar IGBT module excels the wire-bonded IGBT module in the current sharing capability. The gate inductances and resistances are found to be 60% less in the planar interconnect module than in the wire-bonded module. As a result, the power module with planar interconnects yields faster response, which decreases the switching energy imbalance caused by the time lags. The variation of the threshold voltages has a significant effect on the switching energy distribution among the devices. The IGBT with lower threshold voltage tends to be turned on earlier and turned off later than the IGBT with higher threshold voltage. Therefore, a substantial amount of current will travel through the IGBT with lower threshold voltage during switching transient. The continuous operation of the power modules leads to junction temperature imbalance on the IGBTs. The thermal imbalance can further cause imbalance of energy dissipation. Simulation shows that the planar module layout can decrease the impact of layout impedances, thermal imbalance, and process variations.","PeriodicalId":446953,"journal":{"name":"2009 IEEE Electric Ship Technologies Symposium","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132120815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
