摘要
对水电厂如何实行经济调节 ,节水节能的问题进行了研究。通过分析岩滩、大化电厂出力调整后的水头变化、水轮机的运行效率变化 ,指出水电厂如能合理利用水轮机运行特性曲线 ,控制水电厂的运行水头 ,保证机组运行于最佳经济区域内 ,完全可以提高电厂乃至全电网的经济效益。
The problems with the implementation of economic regulation,water saving and energy saving in hydropower plants are considered through the analysis of the water head change and the operating efficiency change of hydraulic turbines after output regulation of both Yantan and Dahua Power Plants The economic efficiency of hydropower plants and the total power networks can be raised by means of reasonable use of turbine's operating characteristic curves and the control of hydropower plant's operating head for assuring units' operation within optimum economic ranges
