Pump station system safety control method and device for hydraulic engineering and pump station system

The invention discloses a pump station system safety control method and device for hydraulic engineering and a pump station system. The method comprises the steps of: after the pump station system isstarted up, detecting an operating state of the pump station system in real time; according to the operating state, judging whether the pump station system reaches a water hammer effect trigger risk threshold; if the pump station system reaches the water hammer effect trigger risk threshold, acquiring a current water body flow rate in a first pipeline, which is measured by a flow meter; and if thecurrent water body flow rate reaches a preset flow rate threshold, controlling a plurality of separation valves to execute an asynchronous closing operation to cut the first pipeline into a pluralityof spaces separated mutually so as to cut off flowing of a water body in the first pipeline. By the method, when a water hammer effect trigger risk in the pump station system is detected out and thecurrent water body flow rate
