The　hydraulic　response　characteristics　of　water　convey　system　is　one　of　the　important　problems　in　the　process　of　channel　operation,　especially　for　the　water　conveyance　system　of　cascade　pumping　station.In　this　paper,　water　convey　system　from　Tundian　pump　station　to　Niantou　pump　station　in　Miyun　reservoir　storage　project　was　taken　as　an　example,　by　means　of　numerical　simulation,　hydraulic　response　process　shutdown　single-stage　pumping　station　and　cascade　pumping　stations　across　the　board　stop　two　emergency　cases　of　water　channel　were　calculated.The　results　of　analysis　show　that　one　single　stage　pumping　station　stop,　while　the　other　pumping　stations　is　in　normal　operation,　the　system　will　gradually　reach　the　limit　level,　When　the　whole　system　is　shut　down,　the　water　level　fluctuation　is　controlled,　and　the　system　has　good　self-regulation　ability.These　characteristics　are　of　great　significance　to　further　study　about　reducing　the　level　of　channel　water　level　and　the　rate　of　decline,　and　to　develop　a　reasonable　and　effective　control　method.　©　2018,　The　Editorial　Board　of　Journal　of　Basic　Science　and　Engineering.　All　right　reserved.
