Abstract

The traditional harmonic suppression method based on the magnetic valve type single-phase controllablereactor has high sensitivity to the interference of ferroresonance overvoltage and poor harmonic suppression effect

which leads to a high amplitude of reactance rate fluctuation. Therefore

in order to solve the problems of traditionalmethods

a new harmonic suppression method for single-phase controllable reactors under ferroresonance overvolt-age interference is proposed. By designing the harmonic suppression scheme of single-phase controllable reactor

thecontrollable reactor is connected to the triangle

the moving winding is connected with the power grid. Based on thesystem capacity and the number of harmonics to be filtered

the harmonic suppression topology results of phase shift-ing windings are obtained. The interphase winding connection measures and phase shift winding are adopted. Thenumber of turns is obtained

and the required phase shifting voltage is obtained to suppress the harmonics formed bycontrollable reactors. The experimental results show that the proposed method is effective for harmonic suppressionof variable frequency motors

and the reactance rate can be adjusted to a reasonable value.
