    AUTOMATION OF ELECTRICAL TRANSMISSION LINES' ROUTE OPTIMIZATION AND PROJECT DRAWING
    (GAZI UNIV, FAC ENGINEERING ARCHITECTURE, 2015) Eroglu, Hasan; Aydin, Musa
    There is a need for new Energy transmission lines (ETL) in order to meet the energy demand that has been increasing from past to present. Finding the optimum route and drawing the project is a time consuming and a complex problem for engineers. There are many studies for optimization of ETL's routing in the literature. However it is seen that there is a need for an interface that will facilitate the ETL routing by bringing together all the processes for ETL routing and preparing the project of the ETL by drawing the profile of the route. In this study, an interface using the Geographical information systems (GIS) is designed for finding the optimum route of ETL's, a project drawing program that can draw the profile and make all the other project processes is written. Also, controlling the project on the real terrain model by the users is ensured by the visualization of the ETL's projects on three-dimensional terrain model and satellite image.

    Genetic Algorithm in Electrical Transmission Lines Path Finding Problems
    (IEEE, 2013) Eroglu, Hasan; Aydin, Musa
    Today, Geographic Information Systems (GIS) solutions have entered every corner of the engineering studies like Electrical Transmission Lines (ETL) route optimization, vehicle routing, power plant siting and so on. Raster-based maps generated by GIS are very useful solutions for this kind of route optimization problems. The weighted sum of all the data can be converted to raster-based maps and gathered consecutively in GIS for ETL route optimization. In this paper, Genetic Algorithm (GA) is applied to ETL route optimization problems in order to find the best route on raster-based maps.

    Optimization of electrical power transmission lines' routing using AHP, fuzzy AHP, and GIS
    (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2015) Eroglu, Hasan; Aydin, Musa
    With the increase of people's need for energy, electrical energy transmission has become a very important issue as well as electrical power generation. One of the most important problems in energy transmission is finding the best route in a very complex study area. To date, many people from different disciplines have come together to find the best routes by manual methods like using paper maps and deciding which route is the least-cost path (LCP) to the destination point. Today it is known that, in engineering problems, and especially in path-finding or site-placing problems, the Geographic Information System (GIS) is the most powerful tool. On the other hand, as finding the best route is a very complicated problem and many criteria should be considered, including slope, landslide, road/railway/pipeline crossing, ice zones, distances to roads, national parks, archaeological areas, residential areas forests, and river crossings, multicriteria decision methods like the analytic hierarchy process (AHP) and fuzzy analytic hierarchy process (FAHP) should be used to make the most accurate decisions. In this study, the AHP and FAHP are used to weight criteria relevant to energy transmission line (ETL) routing. According to the criteria, digital maps of the sample study area are edited, weighted, converted to raster-based format, and gathered using the Environmental Systems Research Institute's ArcGIS Desktop 10 software. After generation of the weighted surface map, the LCP tool is used to find the best route. By selecting different start and end points in the sample study area, accuracy and performance of the best routes according to the LCP algorithm are assessed and some problems of the routes for ETL routing are presented. With this study, mistakes by manual methods will decrease in ETL routing and other routing problems.

    Simulation of a large electric distribution system having intensive harmonics in the industrial zone of Konya
    (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2013) Eroglu, Hasan; Aydin, Musa
    In this study, measurements were taken at different points of a sample distribution system in order to analyze the levels of harmonics that appear as a day-to-day increasing problem in electrical distribution systems. According to the measurement values, the dominant harmonics have been determined and an electrical model of the system has been prepared using the SimPowerSystems toolbox from MATLAB and Simulink. The accuracy of the electrical model has been verified by the measurement and simulation values. In addition, the transformer connection types' and impedances' simulations have been presented to understand and solve the harmonic problems in electrical distribution systems. With the help of this study, advanced analysis can be performed in the electrical distribution system for power quality analyses and this study can be a background for similar kinds of simulation studies.

    Solving power transmission line routing problem using improved genetic and artificial bee colony algorithms
    (SPRINGER, 2018) Eroglu, Hasan; Aydin, Musa
    In engineering studies, finding the best route from a start point to an end point on pixel-based weighted maps is a big problem for researchers. For this problem many methods and algorithms have been developed until now. The "cost distance" (CD) and "cost path" (CP) tools that are used by a modified Dijkstra's algorithm and used by Environmental Systems Research Institute's (ESRI) ArcGIS Desktop 10 software are very fast and most preferred solutions for route optimization problems. Despite the advantages of these tools, they have the disadvantage of making a lot of curves with big angles. Especially in some engineering studies like power transmission lines' routing, the angle of the curves of the lines should not have big values. For overcoming this problem both genetic algorithm (GA) and artificial bee colony (ABC) algorithm that have been improved and adapted for the problem were used as powerful optimizers to find the best routes with fewer curves in those kinds of optimum route problems. New functions like smart direction sensing and improved random functions were developed for application of GA and ABC algorithms in power transmission lines routing studies. This study showed that the ABC algorithm's performance is better than GA. The accuracy of the algorithms was proven by comparing the results with the CD-CP tools' results. The experimental results showed that the improved algorithms gave better performance than Dijkstra's algorithm.
