摘　　要：目前国内新增大型水电项目减少,配合水利项目的消能电站增多。本文以柴石滩生态电站为例,采用特征线方法,仍调压阀口径选取、大小波动分析等方面介绍了过渡过程中条件恶劣的消能小电站过渡过程计算的特点,并对计算控制的标准、阀门边界修改发表了看法,推荐了消能小水电"以阀代井"后负压问题的解决办法和小波动稳定性问题的分析方法。At present, the number of domestic large-scale hydropower projects is reduced, and the number of energy dissipation power stations cooperating with water conservancy projects is increased. Taking ChaiShiTan power station as an example in this paper, the characteristics of the calculation of the transition process of the small energy dissipation power station with the poor transition process conditions are introduced by method of characteristic analysis, the method of regulating valve size selection is also introduced in this paper. The new viewpoints of calculation standard and valve boundary condition are shown. The solutions of negative pressure problem and governor stability problem are recommended.
