Abstract

An adaptive variable structure VDCOL control strategy considering the characteristics of MIDC system based on fuzzy theory is proposed to improve the recovery performance of multi-infeed HVDC system after disturbance. This control combines nonlinear characteristics of fuzzy control with basical mechanism of VDCOL control effectively

and takes the own strength and interactions of multiple DC lines into account

which ensures each current order of MIDC system adjusted dynamically according to system voltage variation and recoveries voltage and power coordinately. The simulation results show that this method can decrease the reactive power demanded inhibit the follow-up commutation failures to accelerate the recovery and ensure the safe and stable of MIDC system.
