Successive commutation failure of UHVDC transmission system leads to a serious temporary overvoltage in sending-side grid, and may cause cascading tripping of renewable energy generators (REGs) nearby. The low-voltage stage before overvoltage stage forces REGs into the LVRT. Both the decrement of active power and the redundancy of reactive power during

Abstract Commutation failure in line commutated converter based HVDC systems cause severe damages on the entire power grid system. For LCC–HVDC, thyristor valves are turned on by a firing signal but turn off control is governed by the external applied AC voltage from surrounding network.
