Abstract：The structural design of penstocks in diversion-type hydropower stations primarily depends on factors such as pipe diameter and internal/external water pressures,with internal water pressure being one of the most critical design bases.To ensure penstock safety,the structural design must incorporate the superposition of static water pressure and the pressure rise caused by water hammer effects.By comparing differences in pressure line superposition methods across various specifications,methods for plotting the maximum internal water pressure line in penstock design were discussed.
