摘要
本文根据南桠河姚河坝水电站的设计方案,对水轮机调节系统,按复杂管道、弹性水锤、调速器为PID调节规律,建立其小波动数学模型。并据此编制了源程序进行仿真计算。通过对该电站水轮机调节系统各种不同工况及参数组合的计算,可得出调速器最优参数组及其调整范围,保证系统小波动调节稳定。
According to the design scheme of Yao Heba power station on Nan Yahe river, the small fluctuation mathematical model with complicated conduit system, elastic water hammer and PID regulating law of water turbine regulation system is presented in this paper. Then by the established source programme the emulation calculation by computer is carried out and after calculating with all sorts of conditions and parameters combinations of water turbine regulation system the optimum parameters and the regulative ranges of the governor are obtained to assure the the small fluctuation stabilized in system.
