Analysis and Solutions for Powerhouse Vibration in Pumped Storage Power Stations
摘要
Abstract
[Objective]With the implementation of China's dual-carbon strategy,pumped storage has become in-creasingly important in the new-type power system dominated by renewable energy resources.As the operating inten-sity of pumped storage units continues to increase,vibration problems of pumped storage powerhouses have become increasingly common.It is necessary to summarize solutions to vibration problems in operating pumped storage pow-er stations and units to guide the design of future stations.[Methods]This study presented the identification of vi-bration sources and solutions to vibration issues of pumped storage power stations in Zhanghewan,Heimifeng,and Guangzhou.Two widely used structural design schemes for pumped storage powerhouses-thick-plate continuous wall structure and plate-girder frame structure-were presented,with a discussion of their advantages and disadvan-tages.Based on the actual cases,the layout of vibration measurement points for both the powerhouse and the unit was provided.Test methods and evaluation indicators were established for powerhouse vibration.[Results]Three typical methods for alleviating vibration in the powerhouse and pumped storage unit were proposed:controlling the energy generated by hydraulic excitation sources,staggering the frequencies between stationary parts and hydraulic excitation sources,improving the local or overall stiffness of structures.For structure stiffness and vibration resist-ance,the thick-plate continuous wall structure and plate-girder frame structure showed no significant difference.For the measurement and calculation of powerhouse vibration,more attentions should be paid to individual structural components to prevent local resonance with hydraulic excitation sources.[Conclusion]Both the thick-plate contin-uous wall structure and plate-girder frame structure can be widely used for pumped storage power stations,depen-ding on specific engineering requirements.The natural frequencies of overall and local powerhouse structures should maintain a frequency deviation of 20％from hydraulic excitation source frequencies.If the vibration velocity is used as an evaluation indicator,the maximum vibration values should be less than 10 mm/s on the powerhouse floor and 5 mm/s in the pit.This study provides important guidance for improving the structural design of pumped storage power stations in China.关键词
