A Novel ConverterTopology Based STATCOM For Reactive Power Compensation

Abstract

In this paper reactive power compensation using an infinite level inverter based STATCOM is proposed. Nowadays, the society is becoming increasingly dependent on the electrical supply. New equipment's are more sensitive to power quality variations. This causes the transmission line to transfer equal or sometimes more than its capacity, which leads to overloading, voltage fluctuations etc. in the system. FACTS devices are developed to mitigate these problems. This will reduce the power quality problems by controlling the active and reactive power flows in the transmission line. STATCOM is normally used for reactive power compensation; hence power factor can be improved. This new converter topology helps to minimize conduction and switching losses and hence to improve efficiency the voltage variation in the transmission line is also mitigated with the help of STATCOM. Simulation using Mat lab Simulink are included.
