On the other hand, one of the methods for assessing the motor internal condition is by the use of Concordia pattern analysis. Though adequate precautionary measures are adopted, the capacitor banks may sometimes malfunction, leading to damage of one or more of the individual capacitors in the whole bank. Such a minor fault in the capacitor bank is often not apparently discernible. This may however, give rise to substantial degradation of power factor correction performance and may also damage the supply profile. The case is more severe with the fact that the Concordia pattern gets distorted due to such external capacitor faults, and can give anomalous results about motor internal fault analyses. The aim of this paper is to present laboratory and field test results to have a close look at the anomalies in harmonic distortion and Concordia pattern analyses in induction motors due to capacitor bank malfunctions.","PeriodicalId":337759,"journal":{"name":"2009 International Conference on Power Systems","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128161014","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}

An isolated distributed generation (DG) system is realised using fixed pitch wind turbine. The proposed stand alone wind energy conversion system (WECS) consists of a permanent magnet synchronous generator (PMSG) driven by a wind turbine. The zig-zag transformer is used for isolation of the VF controller from the system and it provides path for the neutral current of the three-phase four-wire distribution system. The VF controller consists of IGBT (insulated gate bipolar transistor) based voltage source converter (VSC) with a battery energy storage system (BESS) at its dc link. The VF controller injects/ absorbs both active and reactive powers and also acts as a harmonic compensator and a load balancer. The proposed WECS along with its controller is modelled and its behavior is simulated using MATLAB with its simulink and power system blockset (PSB) tool boxes.","PeriodicalId":337759,"journal":{"name":"2009 International Conference on Power Systems","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126576281","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}

An over sizing of the system components significantly elevates the overall cost of the hybrid energy system. In this context the correct and cost effective system sizing as well as efficient system operation is important. In order to determine the optimal sizing of system components, a mixed integer linear mathematical programming model (time-series) has been developed, based on the evaluation of optimized system unit cost for a hybrid energy generation system consisting of small/micro hydro, biogas, biomass, photovoltaic array, a battery bank and a fossil fuel generator. An optimum control algorithm written in C++, based on combined dispatch strategy, allowing easy handling of the models and data of energy system components is presented. The sizing result of the components is based on a trade-off between the optimized cost of the system and other techno-economics parameters, as determined by the algorithm in conjunction with a time-series model. To demonstrate the use of model and algorithm, an application example is also presented.","PeriodicalId":337759,"journal":{"name":"2009 International Conference on Power Systems","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132660611","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}
