摘　　要：本文通过联合建立水力、机械、电气系统的数值仿真模型,研究分析了水电站小波动过程中,电气过渡过程对转速调节品质的影响。结果表明:励磁调节对转速调节的影响是存在的,但在保证发电机端电压有较高稳态电压精度的前提下,此影响很小;在分析带地区负荷机组转速调节过程的时候,不考虑电气过渡过程是可行的。Based on the united numerical models of hydraulic, mechanical and power systems, the influence of electric transient process on speed regulation quality during the process of small oscillation is studied. The results show that the influence of excitation regulation on speed regulation is existent, but it is a little on the premise of higher steady voltage precision. As the process of speed regulation of the units with local loads is analyzed, it is feasible to ignore the electric transient process.
