尾水系统 meaning in Chinese
tailrace system
Examples
- Based on thoma supposition and basic equations of surge tank , a few formulas were proposed for the stable sectional area of tailrace surge tank on complicated tailrace system
摘要在托马假定前提下，从调压室基本方程入手，推导复杂尾水系统的尾水调压室稳定断面计算公式，并通过工程实例进行验证。 - In this case , when one of the machines be placed into the transition process of the vident fluctuating pressure for some kind of reason , the other machines would be affected become of the fluctuating pressure in the diversion system and drainage system of water in upstream and downstream which use the same one surge tank and the same one penstock with the machine , so the other machines would be put into transition process of fluctuating pressure , and become a kind of hydroelectric interfere
在高水头引水式水电站中，通常几台机组共用同一调压井，且共用压力主管。在这种情况下，当其中一台机组由于某种原因处于大波动过渡过程，则其在电站上下游引、尾水系统中引起的压力变化必然会影响与其共用调压井和压力主管的其它机组，使其它机组也处于过渡过程，形成一种水力干扰。 - Abstract : in view of the general phenomena of insufficient resource utilization and inefficient unit operation , an optimal method of power plant economic operation which is fit for the operation characteristic of the small hydropower station has been presented in this paper . on the basis of actual power features of units , this method avoid errors for curve transformation and imitation as well as bring the indefinite factor arising from different combination way of diversion and tail - race system of hydropower station . it makes the calculation result more accurate and reliable . proved by practical application of the hydropower station , this method not only improves the technique content of hydropower station manage , but also promotes clearly economic benefit
文摘:针对目前已建成的小型水电站资源利用不充分,机组总体效率较低的现象，提出了一种适合小型水电站运行特点的厂内经济运行优化方法，该方法以机组的实际动力特性为依据，既避免了由于曲线转换和拟合带来的误差，又可以将电站引水系统和尾水系统由于不同组合方式所出现的不确定因素纳入优化设计之中，使计算结果更加准确可靠.经实际电站的应用表明，该方法不仅可以提高电站管理的技术含量，而且使电站的经济效益有明显的提高
