对于中小型长引水式电站,为满足其调节保证的要求,结合某电站的输水系统布置特点,初步拟定多种调节保证措施的方案,通过调保计算对比提出采用调压阀作为调保措施,同时对选择合理的调压阀启闭规律进行计算分析,以确保电站的安全运行,其结论对中小型电站有借鉴意义。

英文摘要：

To the hydropower station which draws water with long pipes, in order to satisfy the requirements of the regulation guarantee calculation, combined with the layout of water conveyance characteristics, this paper first suggests several methods as regulation guarantee measures, then puts forward a method of pressure regulation valve as regulation guarantee measure after regulation guarantee calculation. How to choose right opening and closing law of valve is discussed to ensure the safety of hydropower stations. The achievements can be useful for other and small and medium-sized hydropower stations.
