Methods for determining a line fault of a power system. The methods include obtaining sampled values of voltages and currents of phases of a power line in the power system, determining a phase compensation voltage of a first phase and an interphase compensation voltage of an interphase loop between a second phase and a third phase, and detecting the line fault in the first phase and/or the interphase loop by comparing the phase compensation voltage and the interphase compensation voltage.

Method of determining line fault of power system

A method includes determining a plurality of devices in a networked state in a substation system, the plurality of devices including host computers, switches, and end devices; determining an inter-device connection relationship of the plurality of devices; and generating a layout view for the plurality of devices based on the inter-device connection relationship. The layout view includes a host computer layer including representations of the host computers. A switch layer includes bus lines representing the switches, and an end device layer includes representations of the end devices, each of the host computer layer and the end device layer being connected to the switch layer.
