The invention discloses an electric performance recognition system for an electric power system, comprising a voltage sampling circuit, a voltage detection circuit, a frequency detection circuit, a USP power supply, a display screen, an LED indication lamp, a storage device, a button module and a single-chip microcomputer control system. The voltage sampling circuit inputs the voltage signals of the input voltage into a voltage detection circuit and a frequency detection circuit after collecting the voltage signal; the signal output terminals of the voltage detection circuit and a frequency detection circuit are connected to the micro-computer control system. The electric performance recognition system for the electric power system performs detection on the output voltage of the power supply through the voltage detection and frequency detection, performs signal processing through a PIC single-chip microcomputer, returns the feedback to the user through the display screen and the acousto-optic indication mode,
