Synchronous Motor
Transient Stability
Lyapunov Method
In this paper, a new stability criterion method, which is applied Lyapunov's direct method, to judge the transient stability of the synchronous motors is presented. The Lyapunov method is able to estimate the systems stability by using a Lyapunov function without solving the nonlinear differential equations. The transient stability analysis very easy if only the energy level of the system is calculated. The construction of the Lyapunov function is generally difficult, hence, using the Lagrange-Charpit method, the Lyapunov function is constructed with systematic procedure.\nThe paper is organized as follows. Firstly, the system equations of the synchronous motor are presented. This system equation includes the effect of the field circuit, so that the product type nonlinearity term is arisen. Secondly, the Lyapunov function is constructed to judge the system's stability. An example of the stability analysis is presented, and the simplicity of the stability criterion is shown. Thirdly, the influence of a machine constant for transient stability is investigated using the Lyapunov method when the synchronous motor subjected to load disturbances. From this results, we can easily find out the stability limits and should obtain useful information in the area of industrial drives. Finally, by experiment on the transient stability limit, validity of the analytic results is shown.
