摘要
某电站结合供水系统所构成的复杂的输水发电系统,为了保证其稳定性和经济性,在系统尾部设置了阀门调节方式。通过详细的数值计算分析,探讨了水力系统过渡过程中需要由阀门对多个目标参数进行综合调节时的准确性与稳定性,提出了分区调节方式,以较简单的控制模式实现了比较复杂的调节目标。
The water transport tunnel is a complicated water supply system in a hydropower station. A set of valves will be set up at the end of the water transport tunnel in order to assure the stability and economical efficiency of the water transport system. Through detailed numerical calculation, the accuracy and stability of the valve multi-objective regulating in pipe network in the tran- sient process of the hydraulic system are studied. A “sub-area control mode” is proposed to realize complex regulating objectives with a simple control mode.
