Hydraulic turbine governor control has played an important role in not only improving power system transient stability but also restraining the low-frequency oscillation and bettering dynamic performance. Different from the former work based on the ideal hydraulic turbine model with accurate parameter, this paper has proposed a nonlinear adaptive control strategy on the basis of comprehensive nonlinear model with inaccurate parameter by utilizing the differential geometry method and adaptive control theory. Computer simulation tests have been carried out in a simple power system. The results verified the suggested control strategy has adapted well to the parameter inaccuracy and performed better than nonlinear control strategy without considering the parameter uncertainty in improving the system dynamic performance and transient stability.
