Therefore, time-delay modeling of hydro-turbine gov- erning system with multi time-scale is addressed to investigate the dynamical behaviors of hydro-turbine governing system. The effects of the multi time-scale and time-delay on the dynamical behavior of the proposed system are analyzed. The fast-slow characteristic of the system is discussed via numerical simulations with the change of time- scale or time-delay. Results suggest that not only the time-scale but also the time-delay have significant impact on the dynamical behaviors of the hydro-turbine governing system. }, issn = {1746-7659}, doi = {https://doi.org/}, url = {http://global-sci.org/intro/article_detail/jics/22453.html} }
