Abstract
In the fault diagnosis method, apparatus, and computer device, the method includes acquiring line voltage values in real time according to a voltage collector connected to phase lines (S); according to the line voltage values and preset system parameters, obtaining a voltage peak balance degree and a phase angle offset of the three-phase power grid (S); and obtaining a fault diagnosis result according to the voltage peak balance degree and the phase angle offset (S). In such a way, a real-time diagnosis operation of whether a three-phase power grid is balanced can be implemented only by performing on-line calculation and analysis on line voltage values, which has simple analysis operation to reduce the system complexity; and only a voltage collector is added, and no other hardware costs are required, moreover high diagnosis reliability is obtained.
