This thesis proposes a method and develops a model for the participation of a combined cycle power plant to power system frequency control. Through the period of integration to the UCTE system, (Union for Coordination of Transmission of Electricity in Europe) frequency behavior of Turkey̕s grid and studies related to its improvement had been a great concern, so is the reason that main subject of my thesis became as أPower System Frequency Controlؤ. Apart from system-wide global control action (secondary control); load control loops at power plants, reserve power and its provision even at the minimum capacity generation stage, (primary control) are the fundamental concerns of this subject. The adjustment of proper amount of reserve at the power plants, and correct system response to any kind of disturbance, in the overall, are measured by the quality of the frequency behaviour of the system. A simulator that will simulate a dynamic gas turbine and its control system model, together with a combined cycle power plant load controller is the outcome of this thesis.

Constant voltage, constant frequency operation of a self-excited induction generator Çalışkan, Ahmet; Üçtuğ, Yıldırım; Department of Electrical and Electronics Engineering (2005) In this thesis, control schemes for the self-excited induction generator are developed with Matlab/Simulink. Self-excited induction generator is considered as a constant voltage-constant frequency supply for an isolated load. A wind turbine is assumed to be the variable-speed drive of the induction generator. Control schemes aim to ensure a constant voltage-constant frequency operation of the induction generator in case of the variations in the wind speed and/or the load. From the general model of the self-...
Design, implementation and engineering aspects of tcr for industrial svc systems Mutluer, Halas Bilge; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2008) Design and implementation of TCR (Thyristor Controlled Reactor) for industrial SVC (Static VAr Compensator) systems require special design. Both power stage and control system design and implementation are thoroughly investigated in this thesis. Engineering aspects of TCR design are emphasized and supported with case studies. As the first case study; a novel, unified and relocatable SVC for open cast lignite mining in Turkey is designed, implemented and commissioned. The second case study is the first 12 pu...
Investigation of Self-Excited Ultrahigh Speed Induction Generators for Distributed Generation Systems Jardan, Rafael K.; Varga, Zoltan; Nagy, Istvan (2011-09-10) Application of ultra high speed induction generators (IG) in a system developed for utilization of renewable and waste energies that can be applied in Distributed Generation System is presented. The energy conversion is made by a turbine-generator set. For the electromechanical energy conversion application of special high speed induction generators has been studied and described in the paper. The design and analysis of the system are relied on computer simulation techniques verified by test results.
Centralized Microgrid Control System in Compliance with IEEE 2030.7 Standard Based on an Advanced Field Unit Pouraltafi-kheljan, Soheil; Ugur, Mesut; Bozulu, Efecan; Caliskan, Bahadir Can; Keysan, Ozan; Göl, Murat (2021-11-01) The necessity for the utilization of microgrids emerges from the integration of distributed energy resources, electric vehicles, and battery storage systems into the conventional grid structure. In order to achieve a proper operation of the microgrid, the presence of a microgrid control system is crucial. The IEEE 2030.7 standard defines the microgrid control system as a key element of the microgrid that regulates every aspect of it at the point-of-interconnection with the distribution system, and autonomou...
Field-Data-Based Modeling of Medium-Frequency Induction Melting Furnaces for Power Quality Studies Yilmaz, Ilker; Salor, Ozgul; Ermiş, Muammer; Cadirci, Isik (2012-07-01) In this paper, the coreless medium-frequency induction melting furnace (IMF) system is represented by alternative field-data-based models, developed specifically for power quality studies. The IMF operation has been represented by a variable series RL circuit, to model the fundamental components of electrical quantities, and a shunt-connected current source, to model the generated harmonics and interharmonics over a typical melting cycle. Both the sinusoidal coding method applied to the major harmonics and ...
