摘　　要：提出了一种基于定子双绕组异步发电机(DSWIG)的交直流混合发电系统。该发电系统能同时输出稳定的变速、变频交流电和高压直流电。系统采取标量型瞬时转差频率控制策略。实验采用一台18k W的双绕组发电机验证了该发电方案的可行性。实验结果显示,该交直流混合发电系统能够在1∶3的宽转速范围内稳定恒功率运行,且具有优秀的动、静态品质。例如,交流输出电压在突加、突卸100%额定负载时,恢复时间小于10ms,大大低于美军标70ms的规定。初步研究成果表明,基于定子双绕组异步发电机的交直流混合发电系统能够为机载、车载等独立电源场合提供有竞争力的解决方案。In this paper, an AC＆DC hybrid power supply system based on dual stator winding induction generator （DSWIG） is proposed. AC and DC power with variable frequency can be generated at the same time by this system. The instantaneous slip frequency based control is adopted here. Experiment on an 18kW DSWIG has been implemented to validate the proposed power supply system. The result shows that this system could operate with wide speed range of 1：3 in the constant power zone with excellent dynamic and steady state performances. Typical features include that the recovery time is less than 10ms when 100% rated AC load is suddenly applied and removed, which is less than the American Military Standard of 70ms. The preliminary achievements indicate that this AC＆DC hybrid power supply system is a competitive solution for the airborne, automotive and other independent power supply applications.
