Identification and Elimination of Faults Occurrence in sub- systems by using Resistance Switching for Linear Loads through Distribution Statcom (D-STATCOM)

This Paper presents the orientation procedure for diagnosing the power quality problems in different fault occurring conditions by using Distribution STATCOM (DSTATCOM) with linear loads. Here the resistance switching is used to get the pure sinusoidal voltage compensation. This modelling and simulation of D-STATCOM is achieved by using pure sinusoidal Pulse Width Modulation Technique. The major problem is that, during fault conditions there is a probable disturbance in the load side and this problem is diagnosing by utilizing the D-STATCOM at load side, as well as in between source and load. This custom power device is an effective and efficient is used in major portion of power distribution networks. D-STATCOM injects a reactive power to correct the fault conditions at end users. Here the SPWM Technique helps to keep controlling the Voltage Source Converter (VSC).The overall proposed topology is modeled and simulated.
