[0002] Harmonic is one of the core indicators of power quality, and the decline of power quality will cause many influences. In addition to additional increase of power consumption, the long-term operation of power equipment under unqualified power quality will also reduce the service life of power equipment. The decline of power quality causes great economic losses to people in industrial production and daily life, and therefore how to realize the governance and management of harmonic becomes a technical problem to be solved.

[0003] In order to solve the above technical problems, the technical scheme in the prior art CN201120182758.3 "Distributed harmonic online detection system based on building equipment Internet of Things" uses a harmonic detection terminal to collect voltage and current signals of corresponding equipment or lines, calculates the effective values of voltage and current and each harmonic, and realizes accurate evaluation of the overall harmonic state. However, at the same time, the following technical problems exist:

Different power equipment injects harmonic frequency and harmonic amplitude of different harmonic frequencies into the power grid, and therefore once the harmonic currents injected by different power equipment into the power grid are superimposed, the harmonic current injected by the entire distribution box node into the power grid may not meet the requirements.
