About this document
Vortex Rope Impact on Francis Turbine Stability by Fabio Folpini is a document available to read on EtoBox.
This document summarizes a paper that analyzes the influence of the location of the vortex rope in a Francis turbine on the stability of the hydraulic system. It presents a new eigenanalysis tool developed to perform modal analysis on the nonlinear differential equations modeling the system in SIMSEN software. The tool linearizes the equations around an equilibrium point to determine the system stability from the eigenvalues. The paper also describes the nonlinear modeling and linearization of hydraulic com
