具有复杂引水系统的龙滩电站调节系统小波动分析

Analysis on small Disturbance in the Regulation System of Longtan Hy-dro-power Plant with Complex Conduit Systems

推导了具有一般复杂引水系统的水轮机调节系统数学模型,概述了几种稳定性分析的方法,并结合龙滩水电站进行了调节系统稳定性和过渡过程品质分析研究。同时,提出了引入水压反馈改善系统动态品质的措施。

The mathematical model for hydraulic turbine governing systems with complex conduits is derived and the methods for some stability analysis are expounded. On this basis, the stability and the dynamic behaviour for the hydraulic turbine governing systems of Longtan Hydro-power Plant are studied and the measure of adopting water pressure feedback is proposed for developing dynamic behaviour of the system.
