Subsynchronous resonance (SSR) occurs when a resonant frequency of a series compensated transmission system interacts with a natural frequency of the turbine prime mover. This form of SSR is referred to as torsional interaction which, under certain conditions, may become self-excited and cause serious damage to electrical equipment and turbine shafts. The presence of a thermal power plant (Kangal) in the close vicinity of a group of series capacitors in Eastern Turkey necessitated a careful investigation of SSR phenomena in the 380-kV network. Extensive computer simulations, utilizing both a frequency-scanning approach and time-domain analysis, revealed that under normal operating conditions the risk is minimal. However, due to inaccuracies in both the machine data and system data, and to the assumptions utilized, the results are non conclusive.

Development of fast and robust spectral decomposition method for nonlinear industrial loads with current frequency spectrum rich in harmonic and interharmonic content
Uz-Loğoğlu, Eda; Ermiş, Muammer; Salor Durna, Özgül; Department of Electrical and Electronics Engineering (2016)
Nonlinear industrial loads such as AC arc furnaces and induction melting furnaces with resonant converters exhibit highly distorted currents rich in harmonic and interharmonic frequency components. Detection of these harmonics and interharmonics is crucial for applying countermeasures to achieve power quality requirements defined by the regulations of the power system operator. Fast and accurate harmonic and interharmonic detection in a power system experiences some difficulties due to the fact that power s...
A Kalman Filter Based Approach for Light Flicker Evaluation of Power Systems
Kose, Neslihan; Salor, Ozgul; Leblebicioğlu, Mehmet Kemal (2009-01-01)
In this paper, a Kalman filtering based approach is proposed to measure the light flicker of the electricity transmission systems. Analytical expressions of the instantaneous light flicker sensation are obtained beginning from a voltage waveform and these expressions are used to obtain a flicker estimation method based on the IEC (International Electrotechnical Commission) flickermeter. In the proposed method, the frequency domain components of the waveform are obtained by Kalman filtering and these compone...
Investigation of parallel-connected GaN E-HEMT VSI-based servo drives
Yürük, Hüseyin; Keysan, Ozan; Department of Electrical and Electronics Engineering (2022-1-19)
Nonlinearities in voltage source inverters (VSIs) are thought to be the primary cause of output voltage distortions which cause low-order harmonics in the output current. These nonlinearities also considerably degrades control performance and system stability for low-speed applications with low-inductance motors, particularly when the system operates in the low-torque area. The impact of the nonlinearities on the phase current and current control of a silicon (Si) metal-oxide-semiconductor field-effect tran...
Investigation of microwave metamaterial based on H-shaped resonator in a waveguide configuration and its sensor and absorber applications
Sabah, Cumali; Taygur, Mehmet Mert; ZORAL, EMİNE YEŞİM (2015-04-13)
A microwave metamaterial (MTM) based on H-shaped resonator in a waveguide configuration is introduced and investigated both numerically and experimentally for X-band frequencies. The proposed model is designed and fabricated on both sides of the substrate and exhibits strong magnetic resonance at around 10.5GHz. Additionally, it has very simple design which improves and simplifies the fabrication process. Besides, only one single slab is used in the simulation and experiment which provides a reduction in th...
Determination of transient stability regions in state space using local Lyapunov surfaces
Eskicioğlu, A.M. (Institution of Engineering and Technology (IET), 1987)
A new approach to the determination of stability regions of multimachine electric power systems is presented, using a Lyapunov function in conjunction with a certain class of unstable equilibrium points. The relevant Lyapunov surface is constructed for each fault, which is considered to be a local approximation to the stability region. Comparison shows that the conservative nature of the second method of Lyapunov is eliminated.
