摘　　要：1 250 kW轧钢机绕线转子电动机节能控制项目,采用智能补偿系统在转子线圈上补偿电流,通过磁场改变定子电流与定子电压的相位关系,提高电机本身的功率因数,达到了明显的节能效果。The energy saving control project of wound rotor motor of 1250 kW rolling mill is adopted intelligent compensation sys- tem to compensate current in the rotor coil. Changed the phase relationship between stator current and stator voltage by the magnetic field, which is improved the power factor of motor itself, and achieved the purpose of energy saving obviously.

关 键 词：电动机节能 转子电流补偿 功率因数补偿 智能控制系统
