Novel protection method for VSC-HVDC transmission lines

Novel protection method for VSC-HVDC transmission lines

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...
