Cascade tandem water diversion type power station adopting pelton turbine
The invention discloses a cascade tandem water diversion type power station adopting pelton turbines, and belongs to the technical field of design and construction of water conservancy and hydropower engineering structures. According to the cascade tandem water diversion type power station adopting the pelton turbines, the height difference between the normal operation water level and the accident working condition upper limit water level can be effectively utilized, the excavation height is reduced, and the energy dissipation requirement is lowered. The cascade tandem water diversion type power station at least comprises a previous-stage water diversion power generation system and an adjacent next-stage water storage adjusting reservoir, the tail water output end of the previous-stage water diversion power generation system is connected with the adjacent next-stage water storage adjusting reservoir, and the cascade tandem water diversion type power station further comprises an emergency water level adjusting system. Each stage of water storage adjusting reservoir is independently connected with the emergency water level adjusting system, and the installation elevation of the pelton turbine of the previous stage of water diversion power generation system is not lower than the highest water level of the adjacent next stage of water storage adjusting reservoir when the corresponding part of the emergency water level adjusting system is at the maximum water level.
本发明公开了一种采用水斗式水轮机的梯级串接引水式发电站，属于水利水电工程结构物设计建造技术领域。提供一种能有效利用正常运行水位与事故工况上限水位之间的高差、减小开挖高度、降低消能要求的采用水斗式水轮机的梯级串接引水式发电站。所述的梯级串接引水式发电站，至少包括上一级引水发电系统和相邻的下一级储水调节库，上一级引水发电系统的尾水输出端与相邻的下一级储水调节库连接，所述的梯级串接引水式发电站还包括应急水位调节系统，各级储水调节库分别各自独立的与应急水位调节系统连接，上一级引水发电系统水斗式水轮机的安装高程不低于应急水位调节系统相应部位处于最大水位时相邻的下一级储水调节库的最高水位。
