EVALUATION OF STATIC SYNCHRONOUS COMPENSATOR FOR DISTRIBUTION SYSTEMS

Power quality problems are an important issue on transmission and distribution systems. These problems can be solved by means of improvements such as power compensation, voltage regulation and harmonic filter. Distribution Static Compensator (D-STATCOM) which is state of art for the Flexible AC Transmission Systems (FACTS), are used for increasing power quality of transmission and distribution system, because of its several compensation capabilities such as reactive power control, voltage sag-swell control, mitigation of flicker and harmonic filtering etc. D-STATCOM is a device connected in parallel to the inverter-based network used in both distribution and transmission systems. In this study, general wavelet algorithm is written mathematically. The performance of this method has been studied and tested using PSCAD / EMTDC software.
