Abstract

An electrical assembly including a voltage sourced converter for connection to an AC network, a controller programmed so that, responsive to detection of a fault in the AC network, the controller obtains a first set of voltage and current measurements taken at an interface connection point, change operation of the voltage sourced converter to inject a modified fault current, and then obtain a second set of voltage and current measurements, determine operating parameters of the voltage sourced converter for injecting a target fault current having a target phase angle that is substantially the same as a phase angle of a reference fault current that would have resulted from operation of the voltage sourced converter in accordance with pre-fault steady-state voltage phase and magnitude values, and operate the voltage sourced converter in accordance with the determined operating parameters so as to inject the target fault current at the target phase angle.
