Distribution STATCOM (D-STATCOM) Voltage Sags, Voltage Source Converter (VSC)


In a Power System there is a main problem of power quality at the receiving side which is mainly related to the voltage fluctuation, current and frequency. The main purpose of this paper is to represents a role of D-STSTCOM in power system before fault, during fault and after fault condition and analysis power quality by using D-STATCOM. When fault occurs in power system at different cases the D-STATCOM will regulate supply voltage by absorbing and providing reactive power to mitigate voltage sag/swell .This model based on voltage source converter and also work on VSC principle. Voltage source converter consist of D.C. link capacitor .The various technique are used for carrying out the work with use of D STATCOM to minimize the problem which occurs in distribution system such as voltage sag, voltage instability in power system with different fault conditions for LG, LL, LLG fault. for supply the reactive power D - STATCOM is used and retain good power quality. The purpose of D-STATCOM is model and simulate using MATLAB/ Simulink version R-2010a.
