Abstract

Many self-contained electrical systems require simultaneous AC and DC power supply. The hybrid AC-DC supply generator (HADSG) is a good solution. Several independent Y-connected windings are equipped on the stator of HADSG, one delivers AC power and the others, termed DC windings, are connected to the bridge rectifier. Methods of parameter measurement considering DC winding resistances are presented for a typical HADSG with a 12-phase DC winding in this paper. The d-axis self and mutual reactances can be acquired by various short-circuit tests for one or two three-phase windings. Relevant formulas are derived for calculating the d-axis parameters through measuring the short-circuit currents and voltages of all open three-phase windings. According to the voltages and currents measured in slip-tests for AC and DC windings, the q-axis self and mutual reactances can be obtained. Using these reactances in the simulation program, the simulation and test results agree quite well.

交直流输出多相同步电机的参数测量

许多自给自足的电力系统需要同时提供交流和直流电源。混合交直流电源发电机(HADSG)是一个很好的解决方案。HADSG的定子上安装了几个独立的y形连接绕组，一个提供交流电源，另一个称为直流绕组，连接到桥式整流器。针对典型的12相直流绕组HADSG，提出了考虑直流绕组电阻的参数测量方法。d轴自抗和互抗可以通过一个或两个三相绕组的各种短路试验获得。通过测量所有三相开路绕组的短路电流和电压，推导出d轴参数的计算公式。根据交流和直流绕组打滑试验所测得的电压和电流，可以得到q轴自抗和互抗。在仿真程序中使用这些电抗，仿真结果与试验结果吻合较好。
