Power quality support for industrial load using hybrid SVC

Dynamic power quality improvement and reactive power compensation are typically done either using SVC or STATCOM system depending on performance requirement. Installation and operational costs of a STATCOM are clearly higher compared to the costs of SVC. The benefit of using STATCOM is 2..3 times higher flicker reduction performance compared to SVC. This paper describes a concept and real time simulation results of the concept, where SVC is combined with SVC to do the power quality improvement and reactive power compensation tasks. The target is to optimise the compensation system in terms of costs, performance and availability.
