We have studied the risks with increased automation onboard ships in a two year multinational joint industry project. The study also included how to deal with emergency situations due to automation system failure. As part of the study we interviewed several individuals from ship owners, ship operators, yards as well as equipment suppliers. Many of the interviewed actors have informal and ad-hoc strategies for managing the software integrated on ships and associated systems. This paper identifies the need for protocols and supportive systems to match these challenges. The explicit need for improvements in life cycle processes, system architecture and quality assurance is also identified as a consequence of the increased exposure to software and software integration with related faults and failures. The paper proposes some recommendations with the purpose of dealing with these challenges.","PeriodicalId":446953,"journal":{"name":"2009 IEEE Electric Ship Technologies Symposium","volume":"18 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":"121276008","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}

Such system is designed to control, for each shipboard generator, the AC machine voltage, the prime mover speed and the interface converter, in an integrated way. Technological aspects and control principle scheme of this system will be presented in the paper, with particular reference to the issue of DC-link voltage stability.

Due to random and non-reproducible nature, the intermittent faults are the most frustrating, elusive, and expensive faults to detect and locate in wiring systems. The novel approach of the author injects a modulated signal or carrier at one location of electrical wire system and diagnoses the health status of the wire by measuring the error rate of the carrier signal at another location of the system. This paper describes the carrier signal technology and its methods devised for detection and location of faults. The paper also reports the functionally tests of the proto board system of the proposed methods. The results demonstrate remarkable consistency in the error rates with staged fault conditions and clear discriminatory capability of locating faulted segment. Monitoring of the disruption of carrier signal over electrical wire between a transmitter and a receiver provides the most effective tool for continuously watching the wire system for detecting and locating the random, unpredictable intermittent faults, the harbingers of disastrous electrical failure.","PeriodicalId":446953,"journal":{"name":"2009 IEEE Electric Ship Technologies Symposium","volume":"54 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":"128570819","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}

Several packages allow the optimization of either the power system functionality or the control system functionality. Research efforts are underway at Mississippi State University to model the protection functionality of microprocessor controlled relays to allow the integration of the protection system and power system models for advanced optimization and simulation analysis related to shipboard power systems (SPS). This paper presents a detailed overview of the overcurrent relay model and procedures used to conduct closed loop coordination testing of relays using a real time digital simulator (RTDS). The coordination of a relay is a useful concept, which is used widely in the protection of a power system.
