Abstract
A method to determine a location of a fault in a power network includes monitoring electrical measurements, receiving an indication of a presence of the fault; determining a first sequence mutual coupling parameter based on the electrical measurements, wherein the first sequence mutual coupling parameter indicates a mutual coupling of a positive sequence to a negative sequence of the power network, determining a second sequence mutual coupling parameter based on the electrical measurements, wherein the second sequence mutual coupling parameter indicates a mutual coupling of a zero sequence to the negative sequence of the power network, determining the location of the fault based on the indication of the presence of the fault, the first sequence mutual coupling parameter, and the second sequence mutual coupling parameter, and sending one or more commands to one or more devices to adjust one or more operations based on the location of the fault.
