摘　　要：分析了双馈电机的运行特性和能量转换特性,以及它在可再生能源发电领域的良好应用前景;在双馈电机和循环变流器数学模型分析的基础上研究了变速恒频(VSCF)运行的矢量控制和磁场定向控制策略,并给出了矢量控制模型,证明了可以通过控制转子电流,实现系统的变速恒频运行和系统输出有功功率、无功功率的独立解藕控制。The characteristics of doubly-fed induction generator operation and power conversion, and good prospects in renewable energy were discussed. Based on the mathematical model of the doubly-fed induction generator and cycloconverters, the stator field-oriented vector control strategy for variable-speed constant-frequency (VSCF) operation was investigated. The vector control model demonstrates the feasibility of VSCF operation and decoupled active and reactive power control by the control of rotor current.
