Background technology
Current direct current generator can produce triple-frequency harmonics during fortune shape, and in industry and household electricity load, resistance sense is born
Carry and occupy very big ratio.Resistance sense loads, and the reactive power being consumed is occupied very in the reactive power that power system is provided
High ratio.Resistance sense load necessary absorbing reactive power ability normal work, this is to be determined by the property of itself.
The non-linear devices such as power electronic equipment also reactive power to be consumed, particularly various phase-control device.As phased whole
Flow device, phased AC power adjustment circuit and cycloconvertor, operationally fundamental current lags behind line voltage, consume big
The reactive power of amount.In addition, these devices also can produce substantial amounts of harmonic current, harmonic source is all intended to consume reactive power.
The application of power electronic equipment is increasingly extensive, also makes power electronic equipment become maximum harmonic source.DC side adopts electric capacity
The diode rectifier circuit of filtering is also the harmonic pollution source punished severely.The fundametal compoment phase place of this circuit input current and power supply
Voltage-phase is substantially the same, thus phasor power factor is close to 1.
(3) magnet can produce magnetic hysteresis and eddy-current loss.
The impact of triple-frequency harmonics generation bad phenomenon:
Cause severe contamination to electrical network, also so that total power factor is very low；
Harmonic wave can cause power system local parallel resonant or series resonance, so that harmonic content is amplified, cause capacitor etc.
Equipment burnout；
Harmonic wave also can cause relay protection and automatics misoperation, so that electric energy metrical is caused confusion；
Outside power system, harmonic wave can produce severe jamming to communication equipment and electronic equipment；
Harmonic wave makes the efficiency of production, transmission and the utilization of electric energy reduce, and makes device of overheating of electrical, produces vibration and noise,
And making insulation ag(e)ing, service life shortens, or even breaks down or burn；
When magnetic field of magnets makes direct-driven servo motor gmd1 rotate handwheel, moment increases.
