Due to their simplicity, high stiffness, low wear and tear, and fast response, they are used for high precision mechanical and electrical engineering applications. However, piezoceramics are dielectric material and they suffer from hysteretic behavior inherent to nonlinear dielectric materials. This characteristic is electrical behavior and affects the micro adjustment and control. To determine the dynamic modeling equations which represent the hysteretic behavior between input voltage and output displacement, we performed the model reduction. This paper, the piezoelectric actuator is treated as second-order liner dynamic system. And the system identification method which deals with the problem of building mathematical models of dynamic systems based on observed data collected from system is used to determine the system constants. A classical PID controller is designed and used to regulate the output displacement, and the PID controller gains which minimize the system error are selected by optimization technique. In this paper, dynamic modeling and controller design method of piezoelectric actuator were presented. For this process, we utilized the system identification method and a classical PID controller. Numerical simulation and experimental test results demonstrate that the hysteresis characteristic between input voltage and output displacement is clearly modeled and endpoint displacement of actuator can be controlled.","PeriodicalId":107016,"journal":{"name":"2008 Joint International Conference on Power System Technology and IEEE Power India Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130961067","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 generation system, during the past eight years, was not in position to meet domestic demand. After the war in Kosovo the shortages of production has required importation of great amount of electricity. Following the intervention of the NATO (North Atlantic Treaty Organization) in 1999 the Kosovo is administrated by the United Nations under Security Council Resolution 1244 (United Nation Interim Administration Mission in Kosovo-UNMIK), first main activities in the energy sector consisted of repairing damaged facilities, rehabilitating equipment that had been inadequately maintained during the years of conflict, restoring production at thermal power stations and in coal mines. One of the most urgent tasks in power sector for the Kosovo is rehabilitation of its thermal power plants and building new generating capacity. In the paper aim to present energy situation in Kosovo and the dilemmas of rehabilitation of old thermal power plant Kosovo A. and to investigate the feasibility of rehabilitation of coal thermal power plant Kosovo A with five units. Further in the paper will be presented: structural changes of power sector; main pieces of Kosova legislation regarding the interaction between energy conversion technologies and environment; evolution trends of the pollution generated by thermal power units; difficulties encountered in the process of alignment to the EU provisions.","PeriodicalId":107016,"journal":{"name":"2008 Joint International Conference on Power System Technology and IEEE Power India Conference","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133185020","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}

Thyristor controlled series compensator (TCSC) are utilized as a conventional means for the purpose while unified power flow controller (UPFC) is the latest converter based devices employing fast power electronic equipments. This paper utilizes the steady state model of thyristor controlled series capacitor and a unified power flow controller for series voltage compensation, and evaluating their range of power flow control for simple network. The models are incorporated into the existing Newton Raphson load flow algorithm. The iterative equations of the Newton Raphson load flow algorithm are modified by the device parameters and the combined set of power flow equations and UPFC or the TCSC control equations are solved for convergence of the formula. Matlab codes are utilized for the implementation of the two devices in the Newton-Raphson algorithm. Power flow control ranges are evaluated for few IEEE bus systems and standard 5 bus system. Results are reported and studies are presented to illustrate and compare the effectiveness of the UPFC and TCSC.","PeriodicalId":107016,"journal":{"name":"2008 Joint International Conference on Power System Technology and IEEE Power India Conference","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114864689","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}
