Additionally, the closed loop torque and rotor flux was implemented so that the induction motor emulates the real behavior of the wind turbine. The wind turbine model is developed considering its aerodynamics characteristic. This model will define the torque level in the electrical generator shaft. The induction motor control system implemented is capable to regulate the electromagnetic torque and rotor flux independently. The simulated results demonstrate the effectiveness of the induction motor system control. The strategy control was implemented in simulation using Matlab/Simulink/SimpowerSystems.","PeriodicalId":442317,"journal":{"name":"2012 10th IEEE/IAS International Conference on Industry Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128335503","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}

Wind farms, cogeneration systems and SHP (small hydropower) are already common elements that can be connected to medium voltage systems (up to 15kV). Additionally, with the development of tecnologies and reduced costs, it is expected that the number of generations connected through the network increases, whether coming from solar collectors, biomass, SHP, wind turbine, or any other popular kind of generation in the future. Based on this premise, a new problem arises, what are the level of real power injection and best place for each connection to the network. The work proposed here aims to develop a method to determines the best connection point for each generation to the network and search the constraint of real power injection of each producer by which the greatest possible reduction of active power flow in its sections, ie, there is a reduction of the maximum load in each line.","PeriodicalId":442317,"journal":{"name":"2012 10th IEEE/IAS International Conference on Industry Applications","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127317340","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 objective is reducing the effects of natural fluctuation observed in measurement dataset resulting from random loading aggregation and disaggregation on the system under study. Specifically, it is used a fuzzy logic system for processing the filtering of measurement data obtained in the field. It is also important to note that the used approach makes the adjustment of the membership functions of a fuzzy linguistic variables using a meta heuristic called differential evolution. As a result, it is possible to get parameters both for ZIP and Exponential models with mean errors lower than those obtained with raw measurement dataset. The validation of this proposal uses measures that have been made at a CEMIG utility substation in Minas Gerais state, Brazil.","PeriodicalId":442317,"journal":{"name":"2012 10th IEEE/IAS International Conference on Industry Applications","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114915985","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}

However, with increasing the number of sensors and equipment emerges a correspondent growth in the amount of data generated. Although the industry stores most of these data in dedicated data warehouse they are rarely used in future analysis due to the inherent technological challenge to properly cope with the large amount of data. This paper proposes the usage of a Knowledge Discovery in Database (KDD) process as a powerful tool to assist one in obtaining relevant industrial behavior from the stored data with the purpose of allowing quality and efficiency analysis. The experiments conducted with data collected in an industrial sugarcane plant successfully demonstrate that it is possible to apply the KDD to predict the ethanol concentration of future harvests.","PeriodicalId":442317,"journal":{"name":"2012 10th IEEE/IAS International Conference on Industry Applications","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133001362","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}
