水轮发电机组是一个典型的非线性系统，不同的导叶开度下其简化线性模型不同。本文分析了水电机组功率波动的原因，提出一种针对不同导叶开度下简化线性模型的自适应校正PID比例增益的控制方法，给出了导叶开度非线性自适应校正控制方法的参数整定方法，并在石门坎水电厂＃2机组进行了现场实施，现场实施和试验表明：该方法实施后机组静态调节误差、功率波动周期、功率波动幅度、调节稳定时间明显改善，有效的提高了机组的调节性能。

Hydro generating plant is a typical nonlinear system,the simplified linear model is different under different guide glade o-pening? This paper analyzes the cause of power oscillation of hydropower plant and proposes an adaptive control method of PID pro-portional gain correction for simplified linear model under different guide glade opening? A parameter setting method of the nonlinear adaptive control method for the guide glade opening is then present and has conducted in field implementation in#2 unit of Shimen-kan hydropower plant? The results of the field implementation indicate that this method has effectively enhanced the regulating per-formance of units and the static regulation error,power oscillation cycle,power fluctuations,adjusting and stabilizing time of units has significantly improved.
