Study of power quality assessment for a photo-voltaic based Distribution Static Compensator (DSTATCOM)

Rana, G and Badu, A J (2014) Study of power quality assessment for a photo-voltaic based Distribution Static Compensator (DSTATCOM). BTech thesis.



This thesis presents an idea of PV cell or battery based dc to dc boost converter which is served to a voltage source converter (VSC) for enhancement of quality of power. A synchronous reference controller is suggested using distribution static compensator (DSTATCOM) in a 3-phase 4-wire transmission system. The DSTATCOM mainly comprises of one VSC and a dc-link capacitor. The main purpose of DSTATCOM is to provide source and total harmonic reduction, reactive power compensation and compensation of neutral current at point of common coupling .A PCC is a point on electricity network where consumer loads are connected. The boost converter used does the work of a chopper. It converts variable output dc to a fixed value of dc by stepping up of voltage equal to the DC-link necessity of voltage source converter. The main benefit of this planned scheme is that, it will always deliver continual compensation for the whole day. To provide separation to voltage source converter and path for fundamental of zero sequence components, one star/delta transformer is employed. It also helps to diminish neutral current by supplying a circulating route in secondary winding of transformer which is delta connected. The required gate pulse to IGBT’s and diode are provided from the PWM controller by using synchronous reference algorithm.
