The paper considers the creation of an intelligent protection system based on fuzzy controllers, which provides detection and effective protection against asymmetric modes, in particular, from open-phase modes in the electrical network of a power system with a complex load. An intelligent system that includes a positive and negative sequence current filter, an analog-to-digital converter, a switch, a calculation unit for the ratio of negative and positive sequence currents, an executive body that turns off the input switch and turns on the sectional switch.
