[0082] A giant hydropower station, the hydraulic turbine type is vertical shaft mixed flow, the water diversion system adopts single-pipe stand-alone mode, rated power is 600MW, rated water head is 111m, and rated flow rate is 597.95m 3 / s, the design value of water flow inertia time constant is 2s.
[0083] Under three operating water heads of 108m, 113.8m, and 117m respectively, the unit has active power of 240MW, 480MW, and 600MW, and a given step of the guide vane is applied to the governor, and the actual active power reverse curve is measured; the statistics of the unit under the three water heads When the rated load is 600MW, the flow rate is 601.32m 3 / s, 561.72m 3 / s, 548.49m 3 / s, substitute the head and flow data into figure 2 The model shown (f(H i )=Q i (i=1, 2, 3...)), then the three-stage correction model of the water flow inertial time constant coefficient can be obtained.
[0084] The water flow inertia time constant correction coefficient is:
