摘要
本文介绍了水电厂实现自动发电控制可取得经济效益的计算方法,并用与过去运行实绩进行对比的方法计算了各种不同类型水电厂用计算机控制后的经济效益,计算表明,不同类型电站的经济效益相差甚大。文章深入分析了影响经济效益的因素,得出的结论是:有调节性能好的水库、参加系统调节、日负荷曲线变化大的水电厂具有最大的经济效益;合理安排机组启停对优化工况至为重要。
The text describes the computational method for obtaining economic benfit for hydro plants under the computer automatic control. Computational results for different hydro plants are listed to compare with those values obtained by the plants in practical operation in the past. The results show that for different hydro plants their economic benefit quite differs from each other. The factors affecting the economic benefit are discussed. The hydro plant with large reservoir capacity, taking part in system regulation and having greater variation in daily load curve, possesses the greatest economic benefit. It is of great imoprtance for optimizing the operational condition to arrange starting or stopping unit operation rationally.
