试论取消水电站调压室的可行性与合理性

On Feasibility and Rationality of Canceling Hydroelectric Station Surge Chamber

调压室是减小水击压力、提高调节系统稳定性的比较可靠的平压建筑物.因而长期以来它是长引水道特别是长尾水隧洞和调峰调频电站最常用的具有自动调节功能的水电站建筑物.但是它需要一定的高度和容积,而且结构复杂施工条件较差,这就使电站投资加大,工期拉长.也很自然地使电站设计者萌发了许多遐想:是否长引水道电站一定要设置调压室,如果取消,其可行性、合理性又怎样呢?

Surge chamber is a fairly reliable level pressure structure of reducing water hammer pressure and increasing surge system stability. Therefore, it is water power plant structure that has automatic regulation function and has often been used in long diversion canal for a long time, especially in long tail tunnel and peak and frequency modulation. But it needs certain height and volume, and structural complex and poor construction condition, which will increase investment and prolong time. This naturally makes designer germinate much reverie: Must surge chamber be set up in long diversion canal development? If not, how about its feasibility and rationality? The following will discuss this problem.
