水电站水力振动实例分析

A Case Study of Hydraulic Resonance at a Hydropower Plant

我国某水电站观察到较明显的水力振动现象及局部破坏事故。本文建立了该水电站有压输水系统水力振动的数学模型，分析了该水电站水力振动的特点，指出水力共振是导致该局部破坏的主要原因。

Evident Hydraulic vibration and related local destruction were observed in a hydropower plant in South China.The mathematical model of the hydraulic vibration in the pressurized water conveying system of the plant is developed in this paper.The characteristics of the hydraulic vibration of the plant are analyzed.It reveals that the hydraulic resonance is the main reason of the local destruction.
