为了满足HL-2A环向磁场的要求,成功研制了两套2500kW感应拖动电机的超同步调速装置。基于交-交变频器,通过对每套2500kW拖动电机采用双馈电机矢量控制技术进行调速后,将两台80MVA机组的最高转速由以前的额定转速1488rpm提高到了1650rpm,每台机组的一次脉冲释能达到500MJ,使HL-2A装置具备了环向磁场达2.8T的能力。
In order to meet the HL-2A ring magnetic field requirements, successfully developed two sets of 2500kW induction drag motor super-synchronous speed control device. Based on the AC-AC inverter, by controlling the speed of each 2500kW tractor motor with doubly-fed motor vector control technology, the maximum speed of two 80MVA units is increased from the previous rated speed of 1488rpm to 1650rpm, once for each unit Pulsed release reaches 500MJ, making the HL-2A device capable of a toroidal magnetic field of up to 2.8T.
