Abstract :
In this article, we studied the transient stability
for a system composed asynchronous generators and
synchronous connecting to a power network infinite using
the method of Lyapunov. The idea is researching the
possibility of using the Hamiltonian energy function as a
Lyapunov function one by one for our generators. After
having verified the three criteria of Lyapunov's method,
we have the possibility for using Hamiltonian energy as a
Lyapunov function. According to the results of the
simulations on matlab software plus these three criteria,
we could affirm that the two machines as well as the
complete system, synchronous generator with
asynchronous generator connected to a SMIB network are
stable in the sense of Lyapunov. In addition, the simulation
results show us that all the saddle knots point are on the
positive side of the axis, except one which is on the negative
side; the latter situation is due to the absence of the wind
(case of an asynchronous generator driven by a wind
turbine).
