    DESIGN AND APPLICATION OF A LABORATORY SCALE UNDERGROUND CABLE MODEL
    (GAZI UNIV, FAC ENGINEERING ARCHITECTURE, 2012) Anadol, Mehmet Ali; Aydin, Musa; Yalcinoz, Tankut
    In this study, design of a physical underground cable model provided by a cascade connection of lumped-parameter equivalent pi (pi) circuits for laboratory scale power system applications is presented. The validity of the model was confirmed by a power transmission system using an infinite bus bar constituted of a static synchronous compensator (STATCOM) and the physical cable model. STATCOM exhibits the structure of a three-phase, twelve-pulse voltage source converter that operates on the principle of microcontroller based reactive power control. In such type of a power system, the effects of powering an unloaded and loaded transmission line, as well as load shedding on the cable line were investigated through various experiments and simulation studies. The simulation models for the power and control systems were built by employing the PSCAD/EMTDC program's C-programming interface and the graphics based models in its model library. The experimental results are compared with the results obtained from the PSCAD/EMTDC simulation program.

    Design and Implementation of a Laboratory-scale Microcontroller-based Multi-pulse STATCOM
    (IEEE, 2012) Anadol, Mehmet Ali; Aydin, Musa; Yalcinoz, Tankut
    In this study, the design and application of a laboratory-scale, multi-pulse Static Synchronous Compensator (STATCOM) are presented, which provides reactive power compensation at the point of common coupling (PCC) for the purpose of enhancing the performance of the AC transmission system. STATCOM consists of two units of three-phase, six-pulse Voltage Source Converter (VSC) bridges, where IGBT (insulated gate bipolar transistor) semi-conductor switches are used. Fundamental Frequency Modulation (FFM) technique is used for controlling the converter bridges. The control system has been implemented with low-cost 16-bit microcontrollers. The validity of the laboratory-scale prototype was examined via experiment and simulation studies performed on an energy transmission system with a busbar. The experimental results are compared with the results obtained from the PSCAD/EMTDC simulation program.

    A real-time extraction of active and reactive current using microcontrollers for a multipulse STATCOM
    (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2013) Anadol, Mehmet Ali; Aydin, Musa; Yalcinoz, Tankut
    In power transmission and distribution systems, the design of a compensator that adjusts the power factor without causing additional power losses requires the determination of the reactive current components that are going to be supplied into the system. In this study, the determination of the active and reactive current components is achieved via the use of the nonactive power theory and a microcontroller-based control system. The control system has been implemented with low-cost 16-bit microcontrollers. This system was used to control a 3-phase, 12-pulse laboratory-size prototype of a static synchronous compensator (STATCOM) with the structure of a voltage source converter. Verification of the STATCOM and its control circuit were examined via experiments and simulation studies conducted on a single-machine infinite-bus power transmission system. The simulation models for the power and control systems were built by employing the PSCAD/EMTDC program's C programming interface and the graphics-based models in its model library. The experimental results are compared with the results obtained from the PSCAD/EMTDC simulation program.
