The proposed system can be operated in three modes: full electric, full thermal and hybrid. The main feature of this system in hybrid mode is the possibility to follow two distinct set-points: one for the propeller shaft speed and one for the electric energy to be generated. The paper introduces the basic configuration and the principle of operation of the system and illustrates a case study with the description of the operating limits of the system.","PeriodicalId":134406,"journal":{"name":"Electrical Systems for Aircraft, Railway and Ship Propulsion","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121882680","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}

Also, final tests of on-ship power systems and generation are simplified considerably. Fault scenarios on-ship and within the harbour grid and the variability of the parameters of on-ship distribution — each ship is special, and large consumers or generators are switched on and off — require fast and robust control. Oszillations in the filters ship-side and harbour-grid-side of the power electronics may result from transients — and can be mitigated by the advanced control schemes. The paper introduces the a flux-based control concept and applies it to the typical structure of a shoreside power supply system, verifying excellent characteristics and robustness even under asymmetric fault conditions by simulation. The quality of the simulation results is cerified by comparison to laboratory experiments.","PeriodicalId":134406,"journal":{"name":"Electrical Systems for Aircraft, Railway and Ship Propulsion","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115430937","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}

A complete mathematical model of the total system has been developed. The dynamic model of the SEIG using a three-phase star-connected induction machine is developed based on stationary reference frame d-q axes theory, with three capacitors connected in series and parallel with the single-phase load. The effect of cross-saturation is also incorporated in the model. The implemented ELC consists of a rectifier-chopper system feeding a resistive dump load whose power consumption is varied through the duty cycle of the chopper. Simulated results are compared with the experimental ones, obtained on a developed prototype of an SEIG-ELC system for the different transient conditions such as sudden application of load, sudden removal of load to validate the effectiveness of the proposed approach.","PeriodicalId":134406,"journal":{"name":"Electrical Systems for Aircraft, Railway and Ship Propulsion","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124677283","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 a representation results in a multiple-input multiple-output control system. In the present article, this complex control loop is studied using well-established control-theory techniques, such as the Nyquist criterion.

The robustness and the quality — especially of the state estimations of the observer — can be improved by the pole-restraining observer (PRO) approach.

The minimization of the torque ripple is the main requirement of the speed-variable drive in order to guarantee safety and comfort issues. Further requirements are relevant in context of redundancy.
