Project Support for Aydogan Özdemir by TÜBİTAK and CONACYT
Jan 16, 2017


Prof Dr. Aydoğan Özdemir of our university has received support for his project in the framework of an alliance between TUBITAK and the United Mexican States National Science and Technology Authority (CONACYT) for his work titled "Corona Discharge Characterization and Electromagnetic Effects of HVDC Transmission Lines". The study, which is one of four projects deemed worthy of support, will also involve Assoc. Prof. Dr. Suat Ilhan of the same department, and Assoc. Prof. Dr. Hasbi İsmailoğlu of Kocaeli University.

The project will examine the use of integrated models including isolator chains, transmission lines and pole structures, along with insulation problems associated with the use of isolators in high-voltage direct current (HVDC). In addition, insulator performance under HVDC and the effects of pollution will be addressed. In the first stage, a closer look at the corona discharging mechanism and a study of the corona model of the HVDC transmission line will be performed, followed by simulation studies using COMSOL Multiphysics software.

In the simulation studies, the aim will be to calculate potential and electric field distributions, corona current, ion current density, and corona losses. The projects’ experimental studies will be carried out at our Fuat Külünk High Voltage Laboratory including Corona cage experiments, experiments with HVDC transmission line models as well as verification experiments using an electrostatic tension meter (voltmeter). The project is expected to shed light on the technical and economic aspects of HVDC systems in Turkey and Mexico, who have been shown to be strong candidates for HVDC applications in the near future.

The project, beginning next month, with a budget of 415.400 TL, is expected to be completed in 24 months.
