In this research work, the transient overvoltage suppression capability and harmonic filtering performance of C-type 2nd harmonic filters are optimized by using two-stage damping resistors; one is permanently connected to the filter circuit, while the other one is switched on by back-to-back connected thyristors during furnace transformer and Harmonic Filter (HF) energization periods. However in conventional C-type 2nd HFs there is only one damping resistor, which is permanently connected to the filter circuit. In conventional designs, either the filtering performance is maximized or transient overvoltage suppression capability is enhanced or a compromise is made between these two objectives. This new configuration of C-type 2nd HF has been applied to a sample iron and steel plant in which two LFs are in operation. For this purpose, an SVC system has been designed and installed which is composed of a thyristor controlled reactor, a 3rd HF and the new C-type 2nd HF configuration proposed in the paper. The results of field tests and simulation studies show that the proposed C-type 2nd HF configuration gives much better results than conventional designs.

Design of Selective Linear Phase Cross-Coupled Dielectric Resonator Filters Ozturk, Onur Ozan; Oruc, Sacid; Alicioglu, Bulent; Yıldırım, Nevzat (2018-11-02) In this paper, a highly selective linear phase filter is designed and implemented in cross-coupled form using dielectric resonators in Ku band to be used as a channel filter in IMUX of a satellite receiver. Extreme delay flatness is required: 1.5 nS delay ripple over 60 % of the passband and 12 nS near the band edges. The initial design is carried out as 10 resonator symmetric cross-coupled filter with all ideal inverter couplings realizing two finite transmission zeros (FTZ) satisfying also the delay flatn...
Design and implementation of a voltage source converter based statcom for reactive power compensation and harmonic filtering Çetin, Alper; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2007) In this thesis, design and implementation of a distribution-type, voltage source converter (VSC) based static synchronous compensator (D-STATCOM) having the simplest converter and coupling transformer topologies have been carried out. The VSC STATCOM is composed of a +/- 750 kVAr full-bridge VSC employing selective harmonic elimination technique, a low-pass input filter, and a /Y connected coupling transformer for connection to medium voltage bus. The power stage of VSC based STATCOM is composed of water-co...
Optimizing transient and filtering performance of a C-type 2nd harmonic power filter by the use of solid-state switches Gerçek, Cem Özgür; Ertaş, Arif; Department of Electrical and Electronics Engineering (2007) In this research work, the performance of a C-type, 2nd harmonic power filter is optimized by the use of a thyristor switched damping resistor. In the design of conventional C-type, 2nd harmonic filters; the resistance of permanently connected damping resistor is to be optimized for minimization of voltage stresses on filter elements arising from switchings in transient state and for maximization of filtering effectiveness in the steady-state. Transformer inrush current during energization of power transfor...
Design and implementation of advanced pulse width modulation techniques and passive filters for voltage source inverter driven three-phase ac motors Nebi, Onur Çetin; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2010) Advanced pulse width modulation (PWM) techniques such as space vector PWM, active zero state PWM, discontinuous PWM, and near state PWM methods are used in three-phase AC motor drives for the purpose of obtaining low PWM current ripple, wide voltage linearity range, and reduced common mode voltage (CMV). In some applications, a filter is inserted between the inverter and the motor for the purpose of reducing the stresses in the motor. The motor current PWM ripple components, terminal voltage overshoots, sha...
