of a synchronous machine connected to an infinite-busbar. The system model includes velocity governor represented by second-order response. The construction procedure is essentially based on the technique which gives generalized energy function of the similar system. The Lyapunov function is then used to estimate the critical reclosing times. The results are compared with those given by conventional function, and are found to be useful.

f the Lyapunov function, which has been developed recently, is applied to a single-machine system with and without a velocity governor. Such method is based on a construction technique of the Lagrange's state function resulting from second-order ordinary differential equations. The stability region given by the obtained Lyapunov function is compared with those given by other Lyapunov functions and is found to be useful in the power system transient stability problem. Furthermore, its construction procedure seems to be concise.
