New Control for HVDC System Connected to Large Windfarm

Abstract

HVDC consisted by self-commutated inverters is able to be applied for power transmission that connecting from a remote large windfarm to weak ac system. Most self-commutated HVDC is applied for connection between two ac systems they have synchronous power sources, but it is not suitable for windfarm that consists of induction generators without synchronous power source. This paper presents new control for the self- commutated HVDC system connected to a large windfarm of induction generators. The effect of the proposed control is shown by EMTP simulation.
