Pilot protection scheme for transmission line of a hybrid HVDC system based on polarity characteristics of current and voltage fault components

A hybrid high-voltage direct current (HVDC) system comprises a line commutated converter (LCC) at the rectifier side and a voltage source converter (VSC) at the inverter side, combining advantages of both LCC and VSC systems. However, the asymmetric converters at both ends of line constrain the dire...
