摘要
通过实际水电站的现实需求,结合励磁控制理论和技术以及建模软件,利用交流励磁电机模型验证其泵站特性,并采用定子磁场定向矢量控制策略和双PWM变频器能够达到控制电机的有功功率和无功功率的目的。运用Matlab/Simulink软件的仿真平台,验证交流励磁电机各方面的功能状况,得到相应的仿真结果。结果分析表明,能够验证交流励磁机的功能,与其他泵机组机器相互调节,扩展泵机组的功能。
Based on the literature research and practical problem analysis of excitation control theory,technology and system modeling,combined with the actual work needs of a hydropower station,an AC excitation motor model with pump station characteristics is constructed,and the stator field-oriented vector control strategy is implemented.It can also control the speed,active power,and reactive power of the motor through dual PWM frequency converter.The simulation platform of Matlab/Simulink software is used to verify the functional status of AC excitation motor in all aspects,and the corresponding simulation results are obtained.The results can determine various functions of the AC exciter and give full play to the potential of the pump unit with high efficiency and energy saving.
