| Abstract: | The VVVF voltage Frequency converter of rolling mill can cause fever, noise and over-voltage of transformer in the process of no load debugging. The mathematics model is set up for the actual project and the calculation shows that the harmonic resonance between the Power system and the frequency converter leads to that problem. This paper also gives some advice to reduce the harmonic resonance in the process of debugging the VVVF voltage Frequency converter. |
