摘要
HL-2A环向场电源系统采用400kVA同轴励磁机作为80MVA发电机组励磁的交流电源,两组三相全控整流桥并联为机组励磁线圈供电(主励),另外一组完成励磁机本身的励磁(副励)。发电机两个错30o Y形绕组接二极管整流柜为环向场线圈供电。发电机组经拖动电机加速到1488rpm处放电,由环向场计算机系统通过控制脉冲发电机组的励磁电流调整发电机的输出电压,实现对环向场脉冲电流波形的调节。
MVA same-axis exciter was applied as AC power supply of 80MVA generator group excitation in the power supply system for HL-2A toroidal field. Two three-phase full-control rectifiers were paralleled to supply for exciting coils of the generator group (main excitation). The exciter self was excited by another rectifier (assistant excitation). Two Y-shape winds with phase-shift 30o of generator were connected to diode rectifier equipment to supply for the toriodal field coils. Start discharge when the generator group is accelerated to 1488 rpm, and the output voltage of generator can be regulated through controlling the exciting current in the pulse generator group by the computer control system of toroidal field, so the pulse current wave of toroidal filed is adjusted.
