A generic algorithm for peak fault current calculation in HVDC links
This paper studies the effect of different DC-link's parameters on the magnitude of peak fault current in the DC link. Formulae are presented to calculate the peak fault current. These formulae are presented for different controller's response time considering/neglecting source inductance (overlap). This paper proposes two algorithms to calculate the peak fault current, based on the results obtained, an approximate formula is derived to give an estimate for the peak fault current for different pre-fault current values. Also, a generic algorithm is proposed to calculate the peak fault current accurately for a delayed or an instantaneous controller action considering or neglecting source reactance.
