摘要
在所研究的具有强弱磁能力的变速永磁同步发电机270 V直流电能系统中,应用PWM整流器及磁场定向控制技术,分析研究了直流母线纯电阻负载模型和永磁同步发电机功率平衡方程小信号模型;基于零极点消除,设计了直流母线电压PI控制器。引入有源阻尼技术,在磁场定向控制Matlab/Simulink仿真及测试平台中加以实现。结果显示,有源阻尼技术能加快直流母线电压在负载变化时的瞬态响应速度。
Based on a variable-speed permanent magnet synchronous generator with strong field-weakening ability,a 270 V DC power system with pure resistive load was analyzed,using PWM rectifier and field-oriented control technology.The small-signal model of PMSG power balance was analyzed,and the DC-link voltage PI controller was designed based on the pole-zero cancellation.Active damping was introduced and analyzed in order to increase the dynamic response of DC-link voltage when a sudden load change occurs in both simulation and test bench experiments.
