The base and maximum speed, torque are determined from the mechanical specifications of hydraulic pump. The drive system is set to have minimum power consumption during the keeping of preset oil-pressure. In order to save the power consumption of hydraulic pump, power and oil-pressure signals are feedback to DSP controller, and SR drive controls the operating speed of SRM. A 2.2 kW, 12/8 pole SR motor and DSP based digital controller are designed and tested with experimental set-up. The test results show that the system has some good features such as high efficiency and fast response characteristics.","PeriodicalId":215165,"journal":{"name":"2005 International Conference on Electrical Machines and Systems","volume":"699 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132421007","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}

We use an experimental system that can simulate the characteristics of a wind turbine in this study, because it is hard to operate an actual wind turbine in a laboratory.

The goal of the shunt inverter is stabling the node voltage and the dc-link capacitor voltage. The d-q math model of shunt invert based on three phase PWM converter is established in the paper. In order to improve the dynamic performance and control precision, the paper propose a double closed loop decoupling control scheme and briefly introduce the proceeding of control system design. Node voltage outer loop control system adopts indirect current droop control, which consists of PI regulation and scaling factors of droop characteristic. A current feed-forward link is introduced into dc-link capacitor voltage regulation. The simulation model is constructed by using MATLAB and the simulation results for a case study indicate that dc-link capacitor voltage and node voltage can be controlled efficiently, attest that control scheme and controller design are viable and effective.

The magnetization is conducted using the own stator and winding of the investigated motor. A range of impulses are applied to the winding to magnetize the magnet and the process is modeled and simulated using finite element analysis. The magnet with various magnetization levels are then used for further characteristic analysis and simulation. Among these magnets, the fully saturated magnet is treated as the case with preassembly magnetization so that the comparison can be made. The results show that less saturated magnet with post-assembly magnetization can possess better characteristic in terms of cogging torque and back electromotive force (EMF) constants.","PeriodicalId":215165,"journal":{"name":"2005 International Conference on Electrical Machines and Systems","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126088415","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}
