Tailwater branch canal damping broad crested weir for restraining ultralow-frequency oscillation of hydro-generator and method
The invention belongs to the technical field of generators, and particularly relates to a tailwater branch canal damping broad crested weir for restraining ultralow-frequency oscillation of a hydro-generator and a method. The damping broad crested weir is a damping broad crested weir with a trapezoid cross section, is arranged at the bottom of a certain tailwater branch canal in front of a commontailwater canal of two hydro-generators, and is equal to the tailwater branch canal in width. The tailwater branch canal damping broad crested weir effectively damps the pressure oscillation of the tailwater branch canal under the condition of guaranteeing the running efficiency of the generator, and has the advantages of easiness in implementation, economical efficiency and applicability.
本发明属于发电机技术领域，具体涉及一种抑制水轮发电机超低频振荡的尾水支渠阻尼宽顶堰及方法。所述阻尼宽顶堰为梯形截面的阻尼宽顶堰，安装在两台水轮发电机共用尾水渠之前的某一台尾水支渠底部，并且与尾水支渠的宽度相等。在保证发电机运行效率的情况下，有效阻尼尾水支渠的压力振荡，具有实施简单和经济适用的优点。
