Research on Operation Stability of Kaplan Turbine at Various Load Conditions
Considering that the operation performance of Kaplan turbines provides critical influence on the energy con-version efficiency and the power system reliability,this paper picked out real-time test data under load conditions for com-parative analysis by means of sensors and instruments associated with numerical simulation,so as to look into the specific parameters relative to the actual stable operation,and investigate the mechanism of the instability as well as prevention measures.It is concluded that operation status and stability of the unit are closely related to the changes in flow character-istics and uneven excitation,which provides theoretical basis for the stability improvement of Kaplan turbines,and also will be of great significance to further enhance the economy,reliability and durability in hydraulic engineering project ap-plications.
