Abstract：This paper proposes a controllable reactor magnetic circuit with function of intrinsic magnetic state regulation based on nanocomposite magnetic material, according to the reliability, energy conversation and intelligence of the power system. Firstly, the magnetization model of the material is studied from the macro and micro aspects, and the relationship between coercivity and remanence of this material is determined. Secondly, nanocomposite magnetic material is implanted into traditionally controllable reactor based on the reluctance of magnetic circuit theory. The structure design and electromagnetic design for controllable reactor are completed. Finally, a novel controllable reactor magnetic circuit is designed, and a prototype of 220V/1kV•A/700mH is set up. The experiment system and its control system are then built. Simulation and experimental results show that the inductance value can be regulated continuously and rapidly based on the nanocomposite core. It can be used for reactive power regulation, and also can be as a new type of intelligence, energy-saving power equipment for the safe operation of the intelligence power grid.
