Multilevel Hybrid DSTATCOM Compensator for Distribution Network Load Compensation

Objective: The power utilized by distribution networks depends on power quality which is a function of harmonics, reactive four & power factor. The effect of harmonics was earlier reduced by passive filters. Such filters have distinct disadvantage of fixed ramp. Statistical Analysis: For overcoming this disadvantage, DISTATCOM components has been proposed. In this case, respective power consumption is cooperated and harmonic injection is minimized LCL based filter reduces DC link voltage rating required for component. Finding: The voltage profile is improved. Utilization voltage source inverter reduces the reactive power compensation. Active and reactive power are individually controlled. From the simulations results it is found that current reduction is up to 55.2% where as voltage reduction is up to 85.1%. Application: The proposed multilevel based VSI in the DSTSTCOM improves the overall performance to a remarkable extent. Optimization of the number of level can be taken up as an extension of this work.
