本文对水电站暂态过程中水击压力的影响进行了探讨。文中提出的水击压力修正系数公式既考虑了机组升速时间,又考虑了该时间内各种水击压力图形的影响。文中论证了机组相对速率升高与水击压力修正系数应当配套使用的原因及重要性。
This paper discusses the impact of water hammer pressure in transient process of hydropower station. The formula of water hammer pressure correction coefficient proposed in this paper not only considers the unit up-time, but also takes into account the influence of various water hammer pressure graphs in this time. This paper demonstrates the reason and importance of the relative rate of unit increase and water hammer pressure correction factor should be used together.
