摘　　要：基于定子电压定向的交流励磁发电机解耦励磁控制策略,采用具有优良输入、输出特性的双PWM变换器,采用高速数字信号处理器TMS320F2812设计实现了交流励磁发电机励磁控制系统。其转子侧变换器采用功率、电流的双闭环解耦励磁控制策略,网侧变换器采用电压、电流的双闭环控制策略。控制系统可实现交流励磁发电机有功、无功功率的解耦控制以及交流励磁变速恒频发电运行,实验结果验证了控制系统的可行性。Based on the stator voltage-oriented decoupled control strategy of AC excited generators（ACEGs）,the excitation control system of ACEGs based on high speed digital signal processor TMS320F2812 was proposed,in which back-to-back PWM converters with excellent characteristics were adopted.The power and current dual closed-loop decoupled control strategy was used to control the rotor-side converter while the voltage and current dual closed-loop control strategy was used to control the grid-side converter.The control system can respectively regulate the active and reactive power and the variable-speed constant-frequency generation is realized.Experimental results are also used to validate the proposed method.
