摘要
本文介绍了长引水隧洞电站调压室的水力特点，提出：从稳定工况下甩负荷或增负荷引起的调压室最高或最低涌波水位，往往不是控制值，尚应对可能出现的涌波叠加情况进行复核，必要时可合理调整运行方式或修改调压室尺寸。文中以天生桥二级和太平驿电站为例，介绍了最不利叠加工况的选择方法。
This paper gives an introduction about the hydraulic characteristics of the surge chamber with long-distance diversion tunnel. It points out that the maximum or minimal surge water level caused by load rejection or load increment under stable operation mode is usually not the controlling value, so the possible surge superposition needs to be checked and, if necessary, the operation mode can be adjusted rationally or the dimensions of the surge chamber can be changed. This paper takes the calculations of the Tianshengqiao Second Stage Hydro-power Station and the Taipingyi Hydro-power Station as examples to illustrate the selection method of the worst combined condition.
