摘　　要：多功能柔性功率调节器具有储能、发电、调相等多种功能,在提高电力系统稳定性和改善电能质量等方面具有良好的应用前景,其储能电机采用带大转动惯量的双馈电机。该文建立了多功能柔性功率调节器(flexiblepowerconditioner,FPC)中的双馈电机数学模型;结合FPC装置的功能目标及运行特点,提出并分析了双馈电机的储能、发电、调相、限速度和浮充电等5种运行状态,提出将功率控制和速度控制2种控制模式下的基于定子磁链定向的矢量控制策略作为双馈电机励磁控制策略。对FPC装置多项功能的实现及各种运行状态之间的动态转换控制技术,在小容量实验系统上进行了实验研究。实验表明该双馈电机系统能完成储能、发电和调相等多项功能,功率控制模式和速度控制模式切换平滑,系统具有良好的动、静态性能。The multi-functional flexible power conditioner （FPC） can perform multi-functions including energy storage, active and reactive power generation, and considerable enhancement of power system stability and quality. The motor adopted in FPC is the doubly fed induction motor （DFIM） with large rotating inertia. A reduced order dynamic DFIM model is derived. Five operation states of FPC is proposed and analyzed, such as energy storage, energy generation, phase regulation, speed limit and floating charge. The excitation control strategy of the DFIM with the combination of the power control mode and speed control mode is described. The FPC multi-functions are investigated on an asynchronous motor of small capacity. The experimental results verify the excitation control strategy proposed and the good dynamic and static performance of the system while switching control mode under various operation conditions.
