抽水蓄能电站导叶关闭规律与尾水调压室阻抗孔尺寸优化研究
Optimization of Guide Vane Closing Law and Tailrace Surge Chamber Impedance Orifice Size in a Pumped Storage Power Station
摘要
Abstract
This study investigates a pumped storage power station in Guangdong Province,China,focusing on optimizing hydraulic transient processes in the water conveyance and generating system.By establishing a numerical model for hydraulic transients,the effects of guide vane closing laws and impedance orifice size in the tailrace surge chamber are systematically analyzed.The results indicate that:For turbine operating conditions,guide vane closing duration significantly influences hydraulic transient guarantee design parameters,and selecting an appropriate closing time can optimize extreme transient values.Besides,increasing the orifice diameter in the tailrace surge chamber outperforms adjustments to tailrace pipe diameter,gate location,or surge chamber location,by significantly improving minimum draft tube inlet pressure and transient process quality.This study provides theoretical and practical insights for designing and operating pumped storage power systems.关键词
