The research progresses on the control factors of the maximum hydrodynamic pressure in the spiral casing,the position and type of the surge chamber,the size of the impedance hole,the selection of control conditions,and the sta-bility of the regulating system are summarized in response to the special problems arising from the transition process of long headrace tunnel hydropower station.The most suitable type of surge chamber for long headrace tunnel hydropower station is recommended.The regulation quality of the regulating system and the regulation mode of the water turbine are issues that need to be further studied.
