The basic principle of the proposed method is that all the fabrication processes for the OTFT array on glass substrate have been completed, and the OTFT is then transferred onto the plastic film. A 5.8-inch diagonal wide-QQVGA OTFT array was fabricated using this technology. We confirmed that degree of substrate deformation with the proposed technology could be suppressed in comparison with that with conventional direct formation method, and also that no significant degradation in the electrical characteristics of the OTFT was observed as a result of the transfer process. It is thought that this will be a key technology for the fabrication of large flexible displays with TFT backplanes.","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129781398","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 wind turbine drives a Permanent Magnet Synchronous Generator (PMSG), which is interfaced with the near UPF converter feeding a resistive load. The performance parameters under study are the Total Harmonic Distortion (THD) of the input currents to the converter and the input Power Factor (PF) to the converter.

Some applied examples of motor drives by the Matrix Converter (Fig.1). This paper presents basic characteristic of parallel-connected dual induction motor drives with the Matrix Converter. Purposes of this system are low cost and saving space in the industrial field to operate plural motors. However, in case of the unbalanced loads, both motors are unstable and each motor makes the speed response differenced to cause the rotor flux change. We indicate the new strategy to control stably by applying the average value control in slip-frequency vector control. Moreover, we propose to decrease the speed response of two motors by choosing feed-forward term in the speed control system applying two degrees of freedom control (2DOF) compared with 1DOF.","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116458918","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 developed approach can effectively monitor the operating states of transformers, thereby protecting transformers from burning by overloading via an early overloading warning system. The proposed method is suitable for many underground distribution transformers using a ZigBee wireless sensor network with minimal power consumption and good communication quality. Transformer load current and temperature are captured via a temperature and current sensing interface and transmitted to the ZigBee wireless network control center via the ZigBee wireless network. A transformer load database is complied. The relationship between load current and temperature is determined using a statistical regression method. The regression model of transformer load current and temperature is derived for temperature sensitivity analysis of transformer loading. The transformer load current variation following a temperature increase is then derived to construct an early warning mechanism for overloading, such that maintenance personnel can take the necessary actions to avoid power interruption and improve power quality.","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134213445","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 existing secondary voltage controller (SVC) has a demerit occurring large transient phenomenon shortly after the SVC begins to work. This malfunction results from the difference of the operation status before and after the SVC operates. For solving the problem and implementing the voltage control safely, the AVMS including the manual operation mode is developed by Korea Electric Power Corporation (KEPCO). As well as the AVMS overcomes the drawback, it can execute the coordination control of both continuous voltage controller (CVC) and discrete voltage controller (DVC). The CVC controls reactive power generation sources such as generator and FACTS devices which can generate reactive power continuously and linearly. Otherwise, the DVC controls the discrete reactive power sources such as switched shunt capacitors and reactors. The performances of the proposed AVMS are carried out by time domain simulation in the Jeju Island power system with real-time digital simulator (RTDS).","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116810057","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 main advantages of these energy sources are their limited environmental impact compared to traditional power sources such as coal- and gas-fired power plants, and at the same time, their ability to be controlled, as opposed to intermittent energy sources. However, controlling an entire array of fuel cells causes problems similar to the ones encountered by thermal power plant operators: how can the operation of such units be optimized? This article describes a method to help reach a better economic performance for fuel cell arrays, in which the individual performance of each fuel cell is considered. The method is based on a hybrid system consisting in a multi-agent system, an expert system and an optimization algorithm for optimally dispatching the load. By enabling the use of storage and the ability to automatically start and stop fuel cells, simulation results show that the energy management system can dramatically reduce running costs, as well as enable a very flexible control.","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122202948","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}
