Abstract:Â In recent years the power quality problems is a big issue in distribution system. A Power quality means maintaining the sinusoidal bus voltage at rated frequency. A power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency that results in a failure or a mis-operation of end user equipments. There are different types of problems in power quality. These problems are power factor, reactive power compensation and harmonic distortion. Different types of FACT devices like as SVC, STATCOM, IPC, UPFC, TCSC, and D-STATCOM can be used to solve these types of problems. Among them D-STATCOM is very well known and can provide cost effective solution for the compensation of reactive power and unbalance loading in distribution system. D-STATCOM is capable to inject a current into the system to correct the power factor and reactive power compensation and harmonics reduction. In this paper the test model of D-STATCOM is showed in simulation to observe how D-STATCOM works. The D-STATCOM applications are mainly for sensitive loads that may be drastically affected by fluctuations in the system voltage.
