In the discussion of nonlinear system, the system is often linearized at the equilibrium point to obtain a linear system which is used as an approximation to the original system to avoid the difficulity of dealing with nonlinear systems. However, there are still some defferences bwtween the linearized system and the original system. The method to be studied is the feedback linearization method which is not the same as the conventional linearization method. The feedback linearization transforms the original nonlinear system into an equivalent linear system via coordinate transfor- mation and stste feedback. In comparision with the conventional linearization method which is just an approximation method, the feedback linearization method is an exact linearization method and thus linear system theory can then be readily applied. In the thesis, the method of feedback linearization is dis- cussed and applied to the dynamic responsive analysis of a single-machine-infinitive-bus power system. First, the applicabi- lity of feedback linearization is analyzed. Then the related pro- blems of dynamic stability and control of the system will be studied under fault conditions on buses and transmission lines. The results reveal that by using the feedback linearization we can derive for the original system an exact linear equivalent model from which precise analysis results can be obtained.
