摘要
结合机电复合调速系统、谐波励磁系统的结构特点,分别推导了调速、谐波励磁系统的数学模型,建立了谐波励磁机电复合调速型移动电站的数学模型,结合阻感型负载派克变换模型,给出了整体仿真框图,并进行了仿真试验。研究结果表明:突加85%额定负载时,转速在1.6s内恢复稳定,电压在1.8s内恢复稳定。最后以装配NJVE4/12F1900L型分配泵、SB-W7-20-2P型谐波励磁电机的复合调速机组进行台架试验。试验结果与仿真结果基本相同,证明了所建模型的正确性。
According to characteristics of harmonic exciting system and electromechanical governing system, mathematical models of the governing system and the excitation system were deduced and finally the mathematical model of harmonic excited and electromechanical governed mobile power station was established. Combined with the Park Transformation model of resistance-inductive loads, the simulation block diagram of the system was set up. The simulation experiments show that when added suddenly 85% rated load,the generating set speed can stabilize within 1.6 s,and the voltage in 1.8 s. The simulation results are validated by bench test data.
