A new protection scheme for hybrid cascaded HVDC transmission lines based on cosine similarity algorithm by REN Xuchao, WANG Ye, DU Yunlong, CUI Yu

“…In order to improve the speed and reliability of DC transmission line protection in hybrid cascade DC transmission system, a hybrid cascade DC transmission line protection principle based on cosine similarity algorithm was proposed. When the line fault of the hybrid cascade DC transmission system was made, the current and voltage would change, so the voltage and current transient components at the first and last end of the transmission line were used to compare the differences of current and voltage fault components through data standardization and cosine similarity algorithm, so as to complete the accurate identification of faults inside and outside the area. …”
