Abstract
This paper presents a new method for faults classification of HVDC system by analyzing the currents and voltages of the system under the Zero-Direct-Quadrature (DQ0) coordinates using Lab color chromatic based monitoring approach. Repeated for several healthy and faulty scenarios in DC side and AC side as well, The DQ0 transformed signals are evaluated for each case, Continuous chromatic monitoring is applied on all signals. A chromatic Lab mapping of short time-slot windows result in providing an early fault detection. The preliminary results show high accuracy in fault type classification as well with short processing time and without the need for any pretraining requirement.
