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
Aiming at the phenomenon of inadequate utilization of resources and low overall efficiency of a small hydropower station, a method to optimize the economic operation of the plant is proposed, which is suitable for the operation characteristics of a small hydropower station. The method is based on the actual dynamic characteristics of the unit and avoids Due to the error brought by the curve conversion and fitting, the uncertainties of the water diversion system and tailwater system of power station due to different combination modes can be incorporated into the optimization design to make the calculation result more accurate and reliable. After the actual power station application It shows that this method can not only improve the technical content of power station management, but also improve the economic benefit of power station obviously
