针对喜河水库典型的日调节特性，分析和讨论了基于发电量最大的水库优化调度方式，得出了提高汛限水位、预泄调度、保持高水头运行、实现梯级水库联调是提高日调节水库经济效益有效方式的重要结论。经喜河水库调度运行实践检验，效果明显。

英文摘要：

Considering the characteristics of Xihe reservoir daily regulation, the optimal operation mode of reservoir is analyzed and discussed based on the generation energy maximum. The conclusion is drawn that raising the limited water level, pre-discharging operation, keeping on the higher water level and joint operation of cascade reservoirs are the effective ways to improve the economic benefit of reservoir. The dispatch ＆ operation of Xihe reservoir has proved its effectiveness.
