This thesis analyses the controlled switching methods applied to modern SF6 type circuit breakers for the purpose of reducing switching overvoltages. Main emphasis is placed on controlled switching methods applied at extra high voltage level, since the cost of failures caused by switching overvoltages is highest in this voltage level. After a brief introduction about circuit breakers in general, switching overvoltages and controlled switching methods are analysed. Also a case study about controlled switching of an unloaded overhead line is provided, and success of controlled switching method is evaluated.

Determination of weak transmission links by cluster analysis Ertuğrul, Hamza Oğuz; Özay, Nevzat; Department of Electrical and Electronics Engineering (2009) Due to faults and switching, transmission lines encounter power oscillations referred as power swings. Although in most cases they do not lead to an eventual instability, severe changes in power flows on the lines may cause the operation of impedance relays incorrectly, leading to cascaded tripping of other lines. Out-of-Step tripping function is employed in modern distance relays to distinguish such an unstable swing but setting the parameters and deciding lines to be tripped require detailed dynamic power...
Thermal analysis of power cables Güven, Oytun; Ertaş, Arif; Department of Electrical and Electronics Engineering (2007) This thesis investigates temperature distribution and hence heat dissipation of buried power cables. Heat dissipation analysis of a simple practical application and the parameters that affect the heat dissipation are discussed. In analyzing temperature distribution in the surrounding medium , a computer program is developed which is based on gauss-seidel iteration technique. This method is applied to a sample test system and heat dissipation curves for several parameters are obtained. Also, current carrying...
Determination of optimum values for voltage setpoints of power stations in Turkey Elma, İsmail; Güven, Ali Nezih; Tör, Osman Bülent; Department of Electrical and Electronics Engineering (2014) Voltage control is performed in three hierarchical levels in Turkish power system: primary, secondary and tertiary voltage control. Primary and secondary voltage controls are defined as the regulation of the voltage at the generator terminal and at the high voltage busbar of the power plant according to the pre-determined setpoints. The determination of the voltage setpoints for the power plants, which is defined as the tertiary voltage control, is performed by the operators in National and Regional Load Di...
Suppression of the Second Harmonic Subgroup Injected by an AC EAF: Design Considerations and Performance Estimation of a Shunt APF Durna, Emre; Gercek, Cem Ozgur; Salor, Ozgul; Ermiş, Muammer (2018-04-01) This paper proposes a design methodology for an active power filter (APF) system to suppress the second harmonic subgroup injected by an AC electric arc furnace (EAF) to the utility grid. The APF system is composed of identical parallel units connected to the utility grid via a specially-designed coupling transformer. Each APF converter is a three-phase three-wire two-level voltage source converter (VSC). The number of parallel APF units, coupling transformer MVA rating, and turns ratio are optimized in the...
Fault detection and service restoration in medium voltage distribution system Altın, Müfit; Özay, Nevzat; Department of Electrical and Electronics Engineering (2009) This thesis proposes an algorithm and develops a program for fault detection and system restoration in medium voltage distribution systems. In Turkey, TUBITAK-UZAY developed distribution automation system including fault detection and service restoration functions for Bogazici Electricity Distribution Company. By the time, expanding of distribution system with nonstandardized infrastructure (for example more than one circuit breaker in the feeder, mesh and closed loop feeder structure), developed automation...
