小型水电站厂内运行优化方法

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

OptimumMethod for the Operation of the Small-scale Hydropower Plant

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.
