摘　　要：数/模混合仿真(D/PHS)是风电技术的一种极具前景的研究手段。文中介绍了实时数字仿真器(RTDS)的特点,对能量型和信号型D/PHS系统的原理和稳定性进行了对比分析。采用RTDS和自主开发的变流器控制系统,设计了双馈变速风力发电机的信号型D/PHS方案,详细阐述了数字模型和控制系统的实现方法。针对一台2 MW风电机组的D/PHS算例验证了文中方案的有效性。The digital/physical hybrid simulation （D/PHS） is one of promising research tools for wind power generation technology. Together with the introduction of the characteristics of real-time digital simulation （RTDS）, the comparative analysis of the principles/stabilities of a power-type D/PHS system and a signal type system are given firstly. With RTDS platform and physical converter control system, the signal type D/PHS scheme for a doubly-fed variable speed constant frequency （VSCF） wind power generator is designed. The RTDS digital model and physical control system are developed respectively, which are discussed in detail. The effectiveness of the proposed scheme is verified by the D/PHS investigation of a 2 MW wind power generator.
