Various design efforts are invested to increase the power density of the motor, as a means to decrease the use of rare-earth permanent magnet (PM) materials. Further, concentrated winding motors are received attention to save the winding effort of the coil. In this work, three motor models are compared in the perspective of motor volume, power density, use of PMs, constant power speed range (CPSR), manufacturing flexibility, cost etc. One is a typical interior V-shape motor, and the other two are concentrated winding motors.","PeriodicalId":101507,"journal":{"name":"2011 International Conference on Electrical Machines and Systems","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116751940","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 results show that the simulation system takes the risk of Sub-synchronous Oscillation (SSO) while TCSC is operating in the capacitive region. Supplementary excitation damping controller (SEDC) is used to mitigate SSO caused by TCSC. A new optimization method which is aimed for the optimal phase compensation is proposed. And this method is realized by using the particle swarm optimization (PSO) algorithm. The simulation results show that SEDC designed by this method has better suitability, and the secure operation scope of TCSC is greatly increased.","PeriodicalId":101507,"journal":{"name":"2011 International Conference on Electrical Machines and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129717390","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}

To use the PV battery array efficiently and properly and to protect it, it is important to build an accurate Photovoltaic array model and to analyze the characteristics of the PV array under different circumstances. The characteristics of mono-crystalline silicon, poly-crystalline silicon and amorphous silicon PV modules' basic electrical characteristics were studied by simulation analysis and the experimental measurement. Depending on the experimental data, the forward circuit model of photovoltaic battery is built up in the simulation platform of MATLAB to compare the differences of the different photovoltaic arrays' electrical characteristics.
