Abstract A design method of flux balanced current transformer based on dynamic reactive power compensation technology is designed in the paper, and its application can achieve accurate measurement of a wide range of fluctuating current. Through the analysis of the working principle and measurement error of the current transformer, the control algorithm of the flux balance current transformer based on dynamic reactive power is proposed, that is, the maximum current tracking on the secondary side of the current transformer is realized by the adaptive disturbance method. Field-circuit coupling model of flux balance current transformer based on Comsol and Simulink co-simulation is established. The effectiveness of the proposed flux balance current transformer model and the feasibility of the control algorithm are verified by simulation and experiment.

Key words： Reactive power compensation flux balanced current transformer field-circuit coupling model adaptive perturbation method
