摘要
Abstract
The unit capacity,total installation machine scale and reference flow of a hydropower are relatively large with ultra long water diversion development,and the utilization water head is relatively high.The pressure difference during the transition process of the upstream surge chamber is relatively high,the surge attenuation is slower,and the hydraulic conditions are extremely complex.The method of operation of the project shall fol-low the hydraulic transient law of hypropower projects with long distance diversion and the principle of"safety and stability".To ensure the safe operation of hydraulic structures and power grids,this article studies the pe-riodic characteristics of water level fluctuations in the surge chamber of a long diversion tunnel caused by single unit load rejection tests and emergency load adjustment in case of accidents,proposed a method to adjust the u-nit load based on the fluctuation of surge water level in the upstream surge chamber.关键词
