There is a method of fault clearance for a voltage source converter that interconnects a DC network and an AC network. The voltage source converter is connected to the DC network via one or more DC circuit interruption devices. The method comprises the steps of: (a) detecting a fault in the DC network; (b) carrying out a primary protection sequence, wherein the step of carrying out the primary protection sequence involves carrying out a first sub-sequence that includes the steps of: i. opening the or each DC circuit interruption device, ii. setting a DC power order of the voltage source converter to zero, iii. controlling the voltage source converter to exchange reactive power with the AC network. |
