    A Computation and Metering Method for Harmonic Emissions of Individual Consumers
    (Ieee-Inst Electrical Electronics Engineers Inc, 2019) Dirik, Hasan; Duran, Ismail Umut; Gezegin, Cenk
    As the ratio of nonlinear loads fed from grids are increasing day by day, harmonic pollution problems seem to be more and more serious. Problems related to harmonics are the main sources of economic losses at power systems. In order to reduce economic losses and provide cleaner grids, utilities need to find new and reasonable ways to control harmonic pollution. A proper way of this is to enforce monetary sanctions to the consumers who are responsible for harmonic pollution. With this way, consumers are encouraged to take necessary actions for reducing their harmonic emissions. However, utilities still need a fair, reasonable, and applicable method for this aim to control harmonic emissions of costumers. In this context, a new method to compute the contribution of individual customers to harmonic pollution of grids is presented in this paper. For this aim, an index representing the harmonic emission level of loads is defined. In the development of the method, responsibilities of utilities and consumers, harmonic limits specified by standards and effects of each harmonic component on grid elements have been especially taken into account. Thus, it has been possible to form a fair, reasonable, and applicable method. Validity of the method is tested by simulations, and results are discussed. At the end of this paper, an experimental setup designed for real-time metering is also presented. This demonstrated the applicability of such a metering device that uses the proposed method.

    Code Generation and Data Process Application Desing for Arduino Cicuits
    (Mus Alparslan Üniversitesi, 2017) Çavus, Volkan; Tuna, Resul; Duran, Ismail Umut
    Data processing cards are needed for transferring the sensor measurements from applications or experimental works to computers. Ardunio is the one of those platforms which is preferred in this kind of works due to its ease of use. The digital and analog inputs of Arduino, which is an open source development platform, allow to read and process the data. In this work, the desired sensors can be chosen amongst the sensors connected to Arduino via the application developed using C# programming language in computer environment. Required Arduino Code in order to use selected sensors can be generated without any programming knowledge. Data come from the sensors over Arduino can be recorded in a specified time interval or instantly. Also, the plots of recorded data can be easily obtained and reported in the desired periods and features. Through with this application, it is observed the researchers, who does not know Arduino Programming and have difficulty to read data on circuits, can do experiments easily. Especially, researchers in the fields of basic science and engineering are identified that they can do their scientific studies by using this application easily without the need for information that they do not need to.

    IMU ile Tarim Araçlarinda Oturma Pozisyonunun Düzeltilmesi
    (Düzce Üniversitesi, 2018) Duran, Ismail Umut; Çavus, Volkan; Tuna, Resul
    Insanoglunun10000 yil önce bitkileri evcillestirmesi ile tarim, insanin varliginisürdürmesinde en önemli unsurlardan biri haline gelmistir.  Tarih boyuncabasit aletler ile gerçeklestirilen tarim faaliyetleri, 20. Yüzyil baslarindanitibaren büyük bir hizla makinelesmistir. Tarimsal faaliyetlerin makineler ilegerçeklestirilmesi sonucu isgücü ve zamandan tasarruf saglanmis ve ayni zamandaverimlilik büyük oranda artmistir. Günümüzde, artan insan nüfusunun ihtiyaciolan tarimsal kökenli besinlerin elde edilebilmesi için tarim makinelerinin kullanimibir zorunluluk haline gelmistir. Tarim makinelerinin getirdigi kolayliklarakarsi egimli ve bozuk arazi sartlarinda uzun süreli olarak bu araçlarikullanmak yorucu olmakta ve bazi durumlarda sagligi tehdit edebilen bir halalabilmektedir. Bu çalismadatarim aracini kullanan sürücünün oturus pozisyonunun, degisen arazi sartlarinaotomatik olarak adapte olabilecek sekilde ayarlanabilecegi bir sistemgelistirilmistir.  Tarim aracinin yeryüzü eksenine göre durumu jiroskop veivmeölçer sensörleri kullanilarak hesaplanmistir. Elde edilen verilerdogrultusunda, PID kontrolöre bagli mekanizma ile sürücü koltugunun arazisartlarina uygun olarak hareket etmesi saglanmistir. Oturus pozisyonunun arazisartlarina uygun olarak degistirilmesi ile sürücünün, özellikle bel bölgesiniegerek, vücudunu arazi egimine uydurma gereksiniminin ortadan kalktigibelirlenmistir.
