Novel protection method for VSC‐HVDC transmission lines
The Journal of Engineering, 2018 The large shunt capacitances on both sides of VSC‐HVDC transmission line will block and reflect the travelling waves when a fault occurs on DC cable lines. When a forward fault occurs, the protection will detect the arrival of forward and backward travelling wave simultaneously. While for a backward fault, the arrival time difference of the forward and
