Microgrids are considered suitable to support the reduction of outage times and system restoration strategies. However, the restoration and operation process of island grids brings out several challenges, for example decreased short-circuit current level. Therefore, the focus of this paper is to address the challenge of the protection system’s behavior within an exemplary microgrid, to integrate adaptive setting control for employed intelligent electronic devices, and to validate the performance with a short-circuit analysis. The short-circuit analysis has been performed statically in DIgSILENT/PowerFactory and dynamically in MATLAB/Simulink. The dynamic study was found to be necessary due to the behavior of inverters influencing the actions of protection devices during faults and to be beneficial for considering post-fault operation.","PeriodicalId":343896,"journal":{"name":"2018 International Conference and Exposition on Electrical And Power Engineering (EPE)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121366257","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}

It is also important to evaluate the calibration uncertainty as part of the calibration for the purpose of mentioning it in the calibration certificate of the thermoresistance. Calibration determines the correspondence between the input and output signal of a temperature sensor. In this case, the calibration of the thermoresistance determine a dependency relationship between the input signal, electrical resistance ($Omega$), and the output signal, temperature °C. A practical method for calibration thermometers with electrical resistance is using calibrators temperature or thermostatic baths, which consists of measuring the electrical resistance of the calibrated thermometer with electrical resistance, and temperature of the working medium in which the calibrated and standard thermometers are immersed, at set point temperature. All the individual uncertainty components of thermoresistance calibration should have predefined values and provide for the total extended measurement uncertainty a smaller value.","PeriodicalId":343896,"journal":{"name":"2018 International Conference and Exposition on Electrical And Power Engineering (EPE)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125171683","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 enhancement such as contrast and brightness manipulation, gray level transform, invert transform and also thresholding techniques are described and implemented using a Hardware Description Language (Verilog HDL).

The different types of electrical machines and their suitability for high speed utilization are discussed. Advantages and disadvantages of high speed reluctance synchronous machines (RSM) in comparison with other types of high speed machines are highlighted. The electromagnetic design of such a RSM is carried out on the base of known design procedures enriched by high speed approach. The stator consists of two layers, three phase winding with 12 and 24 slots will be analyzed to compare maximal, average torque and torque ripple. Calculations are carried out by means of finite element analysis (FEA). The different rotor topologies are designed, with multiple geometrical degrees of freedom. Different rotor topologies are also investigated by means of FEA to be able to compare the maximal, average torque and torque ripple. Further mechanical aspects of rotor for RSM are done. The selection of thickness of tangential and central bridges is taken into account. A mechanical stress in such designed machine is calculated versus various speed.","PeriodicalId":343896,"journal":{"name":"2018 International Conference and Exposition on Electrical And Power Engineering (EPE)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131439396","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 perspective opened by the formulation of technical or economic aim functions becomes engaging for designers, having now the opportunity to argue for the established solutions. If the application of the first three criteria has already been dealt with, such as the ground footprint, the EGR total volume and the total metal mass, the total investment criterion is addressed in the paper. The research also brings a methodological improvement to the case of EGR with vertical electrodes placed after a rectangular contour by fixing the number of electrodes to pare numbers greater than four and looking for correlations between the distance between the electrodes and the length of the electrodes, in order to achieve the chosen rated dispersion resistance. During the searches, identifying a simple, parabolic arc function for the real nonlinear dependence between the vertical electrode dispersion resistance and the electrode length has proven to be a real benefit because it has replaced the solving of transcendental equations with solving second-degree equations. The minimum total investment has different coordinates from the minima of the other optimal criteria, proving once again that they are distinct.","PeriodicalId":343896,"journal":{"name":"2018 International Conference and Exposition on Electrical And Power Engineering (EPE)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134012180","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}
