摘要
Abstract
In recent years,the application of high lift water transmission pipeline in power system is increasing significantly.If there is no reasonable and reliable water hammer protection for pumping accidents,water transmission pipeline is likely to occur destructive water hammer incidents.Based on the example of water transmission project in a power plant of Guizhou province,pump-stopping water hammer effects on water transmission pipeline are analyzed by water hammer analysis software and effects of various protective measures are also compared in this paper.Then a kind of water hammer protection measure is proposed which combining two-phase valve shut-offprocedure,air pressure tank and gas injection micro-drain valve.The results in this paper can provide reference for the design of similar high lift water transmission pipeline projects.关键词
