摘要
为提升抽水蓄能电站运行效率与稳定性,需深入研究尾水调压室的动态响应特性。针对当前设计理论局限、工况适应性不足及系统协同性差等问题,引入计算流体动力学(computational fluid dynamics,CFD)技术优化调压室几何参数,并结合动态数学模型分析其在复杂工况下的行为。同时优化机组启停及负荷调整策略,实现渐进式操作以减小压力波动,并通过建立水力耦合模型加强调压室与尾水隧洞、机组间的协同运行。工程应用表明,优化设计有效改善了调压室动态响应特性,提升了系统稳定性并降低了安全风险。未来研究将向多学科交叉、智能化监测控制及系统级融合方向发展,进一步推动抽水蓄能电站的技术进步与可持续发展。
To improve the operational efficiency and stability of pumped storage power stations,it is necessary to conduct in-depth research on the dynamic response characteristics of tailwater surge chambers.Aiming at the current problems such as limitations in design theory,insufficient adaptability to working conditions,and poor system synergy,computational fluid dynamics(CFD)technology is introduced to optimize the geometric parameters of the surge chamber.Combined with dynamic mathematical models,the behavior of the surge chamber under complex working conditions is analyzed.Meanwhile,the unit start-stop and load adjustment strategies are optimized to realize progressive operations,thereby reducing pressure fluctuations.In addition,a hydraulic coupling model is established to strengthen the coordinated operation between the surge chamber,tailwater tunnel,and units.Engineering applications show that the optimized design effectively improves the dynamic response characteristics of the surge chamber,enhances system stability,and reduces safety risks.Future research will move towards interdisciplinary integration,intelligent monitoring and control,and system-level integration,further promoting technological progress and sustainable development of pumped storage power stations.
