抽水蓄能电站洪水调节时段选择浅析OA

Due to the typical location of pumped storage power stations in deep mountains and gorges,their design floods exhibit typical characteristics such as"rapid convergence,steep rise and fall,and short duration."Moreover,the power generation process may coincide with flood events at any time.The time step,as the fundamental unit for discretized solution in flood regulation,directly affects the accuracy of water level calculations.This study takes four pumped storage power stations—DB、SYS、SZS and TC as examples to analyze the impact of the flood regulation time step on the design and check water levels.The results indicate that when the flood regulation time step is reduced to 0.167h,the flood regulation water levels of four stations meet the accuracy requirements.This finding can serve as a reference for similar engineering designs.
