Analysis of design factors for pumped storage power stations with long tailrace open channel
摘要
Abstract
Due to factors such as active fractures,the water transmission system of pumped storage power stations needs to be connected to the lower reservoir through long-tail open channels.However,the frequent start-up and shutdown operations and working condition changes of the units in pumped storage power stations will significantly deteriorate the flow pattern of the long-tail open channels,causing adverse phenomena such as surging waves and water jump fallback,seriously threatening the durability of the lining structure and the overall safety of the project.Based on this,on the basis of analyzing the influence mechanism of factors such as the length,roughness and operating conditions of the tailwater open channel on water flow fluctuations,this paper expounds the design key points such as open channel route planning,inlet/outlet selection and lining structure design,and proposes targeted strategies such as strictly controlling the start-stop rate of the unit,constructing a real-time monitoring system and optimizing operating parameters based on monitoring data.Based on engineering cases,the flow fluctuations of the tailwater open channel are analyzed and specific design suggestions are given.The relevant achievements can provide references for the design and operation of the pumped storage power stations with long tailrace open channel.关键词
