Abstract:

This paper proposes a harmonic detection method based on Duffing oscillator to improve the method of distinguishing the phase diagram.A system is designed for harmonic detection in power system and simulation results verify the validity in the higher harmonic detection.This research offers a basis for the design of new type harmonic time domain detection instruments in electric power system.

Key words: harmonic in power system;chaotic oscillator;phase diagram distinction;signalnoise ratio (SNR)
