Governance harmonic preventive measures. Preventive measures to avoid the solution refers to the harmonic and its consequences appear as follows. (1) Rectifier phase offset (by selecting the appropriate phase shift, harmonic control agents, the high number of pulse rectifier by the low number of pulse rectifier configuration can eliminate harmonics) or harmonic control. It should be used with a higher number of pulse rectifier, such as 12-pulse rectifier to replace the 6-pulse rectifier. (2) the development of effective procedures and methods to control, reduce or eliminate harmonics of power system equipment. 3. Governance harmonic remedial measures. Remedial solution is to refer the issue to overcome both harmonic techniques used, including the use of LC passive filter, the use of active filter circuit detuning, see the following treatment methods. AC power system, harmonic control sales, supply equipment containing a lot of harmonics can be modeled as a linear load and a series of harmonic current sources. It is believed that harmonic control, non-linear loads connected to the AC power to the AC power draw fundamental current feedback of harmonic currents of various frequencies from the AC power source. Harmonic current value and the source resistance greater harmonic voltage waveform distortion caused by the greater, the greater the harm caused.
