Özet

This paper introduces a fuzzy controller of the rectifier side in high voltage direct current (HVDC) system. Especially, rectifier side of the typical point-to-point system has been taken consideration. In the rectifier, thyristors are used as control devices that can handle high voltage and power. Turn on, turn off triggering and protections of these devices have lots of problem and are very sensitive. Especially, in changing voltage and frequency, these problems are appeared itself. Therefore, de current of the rectifier output becomes unstable. Also, device dissipation, transmission losses and effects of environments cause increasing of these problems. In this study, a fuzzy controller is designed to solve these problems. Finally, a comparative study has been performed with and without fuzzy control.
