Lightened on the turbine valve controller designed with feedback linearization theory and introduced nonlinear tracking-differentiator, a novel nonlinear PID valve controller was proposed. This controller can fit not only to plant with some model error and random disturbance in variable, but also to the variety of the structure and operating conditions of power system. The transient and dynamic characters of the controller are both satisfactory when big and small disturbances added. The good performance, wide stable margin and heavy robustness of the valve controller proved that it is a great practical application to enhance the stability of power system.

After years of research, direct method using transient energy function of power system has gotten important development, and has become the main method of time-fiend analysis. In chapter 2, basic theories of TEF method are introduced, and the EEAC method and its application in stability generator tripping control are discussed carefully. A lot of work still need to be done in order to make practical achievement.As a way to actualize this scheme, a new intelligent style under frequency and

A novel quasi-constant frequency hysteresis PWM control approach is presented in this paper. Frequency feedback is introduced in hysteresis current control to stabilize switching frequency. Comparing with the common used constant frequency current mode control, the new approach has better stability, faster transient and higher precision, as well as elimination of sub-harmonic oscillation.

At present, most hydropower plants close the wicket gate by using the closing law with two or three slopes. In fact, as the unit capacity goes up and the turbine working range of water head be even wider than before, so that the fixed closing law with two or three slopes can't control the unit stability effectively when the big fluctuation transient comes op.
