Development Of A PCC Based Stepping Motor Driven Dual Control Governor For Hydraulic Turbine

A PCC based stepping motor driven dual control governor for Kaplan turbine is presented in this paper. The governor adds the function of adaptive control of blades and Radius Basis Function cam network based on the current PCC based stepping motor driven single control governor. It makes hydraulic turbine running with peak efficiency all the time.The governor is designed with model structure. Closed-loop start-up strategy is applied during running and it realizes three adjust mode-frequency, wicket gate and power. It can find the better cam data with adaptive control for runner and optimal cam data based on PCC automatically and calibrate the cam relationship between wicket gate and runner blade by RBF network with better learning and approaching ability learning cam data. It improves the departure of cam relationship during long time running and realizes the continual cam data in the whole cam space.The evaluation of cam data has two methods: linearity and RBF net function. It has four operate method: auto, electric cam, electric none-cam and manual. Finally, matlab simulink account for RBF net can descript cam relationship at better level. At same time, list some required test. This can make governor run with high accuracy and reliability. The governor has certain practicability and provides a stability basis for the development of intelligent governor for hydraulic turbine.
