摘　　要：为研究对不同工况下，洛马乌（Lomaum）电站带孤网负荷运行时的小波动过渡过程和稳定性，采用当永态转差系数6卢为零时，调速器（PIE）调节器和电液随动系统）传递函数为数学模型，采用遍历法对调速器的参数优化计算。结果表明所研究方案的调节系统是稳定的，在五台机组同时带大孤负荷时，调节系统稳定性较差；在部分机组带孤负荷和机组空载时，调节系统稳定性较好。Research on the small-scale fluctuating in transient and stability of Lomaum hydropower stations under different working conditions with isolated load run. The speed controller （PIE） adjuster and electro-hydraulic servo systems） transfer {unction model is adopted when BP is zero. The traversal method is used on parameters of speed optimization. The results showed that the control system is stable, five units is run at the same time with da solo loads, poor system stability, while in some units with a solitary unit load and no-load, regulating system stability is good.
