This paper analyzes the influence of the turbine speed change on the water hammer process line of the water diversion pipeline, and gives the analysis and determination method of several characteristic parameters of the water hammer process line due to the change of the number of revolutions. In particular, it is pointed out that the dynamic characteristics of water turbines with low head flow have an important impact on the water hammer phenomenon. This article also discusses the characteristics of various research approaches to water hammer problems.
