What are the functions of a hydropower station’s pressure regulation chamber? We welcome active participation in discussions; the system offers generous rewards for answering questions from VIP members! ! !
The upstream surge chamber in a hydroelectric power station is used in the pressure-fed water delivery system; its main function is to reduce the water hammer pressure in the pressure water conveyance channels (pressure tunnels, pressure pipes), thereby preventing damage to them. The downstream pressure regulation chamber (tailwater pressure regulation chamber) is used to prevent large negative pressures from damaging the turbine and the tailwater structures; it is employed very rarely.

(1) Reflecting the water hammer wave essentially prevents (or reduces) the water hammer waves coming from the pressure pipeline from entering the pressure intake duct. (2) It reduces the length of the pressure pipeline, thereby decreasing the water hammer pressure in the pressure pipeline and the water-passing sections of the plant. (3) Improve the operating conditions of the unit under load variations. (4) Since the water pressure in the water conduit between the reservoir and the surge chamber is low, its design standards are reduced, saving on construction costs.
