Stability Analysis and Research of Transient Process Caused by Small Fluctuation in Inclined Ceiling Tailrace Structure

In this paper, beginning with the basic equations of hydrodynamics, turbine and governing system, the author deduced the basic equations of transient process caused by small fluctuation in the inclined ceiling tailrace, then analyzed and calculated the basic equations. At last, the author discussed the normal and basic law in the light of basic data in a real power station. The research and results in this paper can give some referencs and advices for the relevant research in the future.
