【 摘 要 】

This paper deals with a hybrid shunt active power filter applied on 500 kV HVDC, after a description of the causes and effects harmonicpollution which may damage equipments and interrupt electric power customers service; in this paper we present the deferent solutionsof this problem among one has to study the two most recent types of filtering: passive and hybrid filter. The hybrid filter consistsof active filter connected in shunt with passive filter. The hybrid shunt active filter proposed is based on three levels PWM inverterand characterized by detecting the harmonic current flowing into the passive filter and controlled by notch algorithm. This structurehas been applied on a test HVDC power system, is presented as a technical solution makes it possible to eliminate the disadvantagesfrom passive filtering, and also economic price of active filtering part. The simulation results justified the effectiveness of thistype of filter face of the classic passive filter.
