This paper discusses the quantitative cognitive engineering of a decision support system to improve the situational awareness of the operator working in a real-time environment. The quality of decision results in reconfiguration of a power system network is compared with and without the decision support system. Within the reconfiguration activities, lack of awareness of the uncertainty present in load data will restrict the reconfiguration algorithm to give a new optimized power system topology. Uncertainty due to faulty metering is duly analyzed and a fuzzy based approach of dealing with uncertainty is explained.","PeriodicalId":446953,"journal":{"name":"2009 IEEE Electric Ship Technologies Symposium","volume":"41 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":"127919172","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 control system plays a critical role in achieving the synergistic operation of various subsystems, improving the reliability of operation, and reducing the maintenance frequency and costs. This paper aims to investigate different control strategies for the power sharing between the subsystems. An internally-reforming SOFC/MT hybrid power system is considered for development of advanced control algorithms, where the anode exhaust, which contains the remainder of the fuel, is mixed with the cathode exhaust in a catalytic oxidizer in which oxidation of fuel is completed. The hot oxidizer exhaust is expanded through the turbine, driving an electric generator. The power electronics interfaces and controls for the hybrid power system are discussed. Two different power sharing strategies are studied and compared. Simulation results are presented and analyzed.","PeriodicalId":446953,"journal":{"name":"2009 IEEE Electric Ship Technologies Symposium","volume":"75 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":"115965035","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}

This approach is based on power exchanges and highlights the most influential parameters of a complex system, without having to choose particular technological solutions.

This approach has been efficiently used for the optimal sizing and control of a hybrid sailboat which comprises a thermal engine and two electric motors in serie configuration associated with sails. The control strategy is organized in two levels: a global one, which defines power objectives, and a local one, which maximizes the efficiency, while guaranteeing the security of each component.","PeriodicalId":446953,"journal":{"name":"2009 IEEE Electric Ship Technologies Symposium","volume":"1 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":"128729154","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}

This energy flow can be complex in nature, making it particularly difficult to sufficiently protect the network effectively. Through the analysis and simulation of a representative zonal DC marine network, this paper analyzes the causes and severity of overvoltages which can occur following a fault, identifying key contributing factors. The paper also demonstrates how the effects of a fault on the network can propagate, potentially causing damage to previously healthy parts of the network. Through this analysis, this paper identifies options for the mitigation of overvoltage transients in DC marine electrical systems.","PeriodicalId":446953,"journal":{"name":"2009 IEEE Electric Ship Technologies Symposium","volume":"1 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":"128736718","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}

Network robustness seems to be correlated with certain statistical properties, which may give rise to a natural design procedure wherein the statistics of the network become the main design goals. This would represent a departure from the current design paradigm. We have performed systematic cascading failure simulations based on a notional cruiser topology, in comparison with equalcost random and scale-free networks. Although preliminary, our results show that some advantage can be obtained through the alternative designs.","PeriodicalId":446953,"journal":{"name":"2009 IEEE Electric Ship Technologies Symposium","volume":"17 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":"115248757","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}

In a highly-integrated dc power system, the preponderance of power converters connecting several loads with power ranging from (W) to (MW) levels rises additional concerns about the effects of a dc fault on other loads connected to the same bus or adjacent buses. Equally critical are the interactions between these power converters during the fault isolation and clearance process. In order to address some of these issues, a basic model has been constructed to study the behavior and effects of dc faults in an MVDC power system for an all-electric ship. Results of the analysis are presented.","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":"121557628","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 damages or faults might even affect the generators and as a result, critical loads might suffer from power deficiency which may lead to an eventual collapse of rest of the system. In order to serve the critical loads and maintain a proper power balance without excessive generation, the ship power system requires a fast reconfiguration of the remaining system under fault conditions. A fast intelligent algorithm using the small population based particle swarm optimization (SPPSO) for dynamic reconfiguration of the available generators and loads when a fault in the ship power system is detected is presented in this paper. SPPSO is a variant of PSO which operates with fewer particles and a regeneration concept, where new potential solutions are generated every few iterations. This concept of regeneration makes the algorithm fast and enhances its exploration capability to a large extent. The strength of the proposed reconfiguration strategy is first illustrated with Matlab results and then with a real-time implementation on a real time digital simulator and a digital signal processor.","PeriodicalId":446953,"journal":{"name":"2009 IEEE Electric Ship Technologies Symposium","volume":"32 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":"131515185","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}
