An effective harmonic suppression solution [Copy link]

In the power grid, there are a large number of nonlinear loads, which cause the grid current waveform to no longer be a sine wave. This non-sinusoidal wave can be decomposed into a DC quantity, a fundamental sine quantity and a series of higher harmonic sine components whose frequencies are integer multiples of the fundamental frequency using Fourier series. For the voltage emitted by the current three-phase AC generator set, the fundamental wave is considered to be a sine wave, that is, there is basically no DC quantity and higher harmonic components in the waveform. However, due to the existence of various harmonic sources in the power system, the interference of higher harmonics has become a major "public hazard" affecting the quality of power in the current power system. All countries have clear regulations on the limit values of the sine waveform distortion of the power grid voltage, requiring users to take certain measures to suppress the harmonics generated by the equipment connected to the power grid.
