研究了部分负荷下尾水管水流引起的水电厂系统振荡。采用一维水击分析和尾水管涡带三维流动计算相耦合的方法。通过这种方法，不必估计振荡的激励、频率和振幅，而是从模拟中获得。这样可以准确预测尾水管喘振引起的系统振荡。版权所有© 2003 by ASME
The system oscillations of a water power plant caused by the draft tube flow in part load are investigated. A coupled simulation of a one-dimensional water hammer analysis and a three-dimensional flow calculation of the draft tube vortex rope is applied. With this approach the excitations of the oscillations, frequencies and amplitudes, have not to be estimated but are obtained from the simulation. This allows an accurate prediction of the system oscillations caused by draft tube surge.Copyright © 2003 by ASME
