PROJECT TITLE :

A Hybrid-STATCOM with Wide Compensation Range and Low DC-Link Voltage - 2016

ABSTRACT:

This paper proposes a hybrid static synchronous compensator (hybrid-STATCOM) in an exceedingly 3-phase power transmission system that includes a wide compensation range and low dc-link voltage. As a result of of these prominent characteristics, the system prices will be greatly reduced. In this paper, the circuit configuration of hybrid-STATCOM is introduced first. Its V-I characteristic is then analyzed, mentioned, and compared with ancient STATCOM and capacitive-coupled STATCOM (C-STATCOM). The system parameter design is then proposed on the basis of consideration of the reactive power compensation range and avoidance of the potential resonance drawback. After that, a management strategy for hybrid-STATCOM is proposed to permit operation underneath completely different voltage and current conditions, like unbalanced current, voltage DIP, and voltage fault. Finally, simulation and experimental results are provided to verify the wide compensation range and low dc-link voltage characteristics and the good dynamic performance of the proposed hybrid-STATCOM.
