水轮机压力脉动分析

Pressure Pulsating Analysis of Hydraulic Turbine

水轮机压力脉动是引起水轮发电机机组振动及不稳定运行的重要因素之一,是评价水轮机水力性能的重要依据之一。文章论述和分析了几种典型的水轮机压力脉动形式及其对水轮机运行稳定性的影响,并介绍了减轻和避免压力脉动可采取的方法。

One of important factor which influences the unit vibration and unsteady operation of hydraulic turbine generator units is the pressure pulsating of hydraulic turbine, and it＇ s one of important basis of evaluating the waterpower performance. The paper expounds and analysis several typical forms＇ represent of pressure pulsating of hydraulic turbine and its influence on the stability of the hydraulic turbine operation, as well as introduces some adoptable methods that could lighten and avoid the pressure pulsating.
