Abstract: Surge chamber is a common solution to ensure the stability of operation and power supply quality of hydroelectric power. Taking the differential surge chamber and the impedance surge chamber as the contrastive objects, two kinds of water energy self regulating surge chambers were designed innovatively in this study, one was the type of strong impact valve isolation and another was the type of surge power generation and energy consumption with aeration. These two surge chambers focus on optimizing the energy dissipation mode of traditional surge chambers. On the one hand, the project cost can be reduced by reducing the fluctuation amplitude of surge tank water level. On the other hand, the power supply quality of hydropower station can be better guaranteed by accelerating the attenuation of surge tank water level fluctuation. By a serious model tests, the technical feasibility of the two surge chambers was demonstrated. The conclusions were as follows: the surge chamber of valve isolation and strong impact was technically feasible and had good performance in all aspects, it could be used to the hydropower stations with medium and high water head like differential surge chamber. The surge chamber of surge power generation and energy consumption with aeration had some effects on controlling the height of the surge wave and the attenuation time of the wave, and it can be used as a technical improvement plan for traditional impedance surge chamber.
