In a single$-$machine infinite bus system, it is assumed that the generator$$s voltage E$$ remains constant during the transient process. Under normal operation, the power angle $\backslash$delta $0=30\backslash$deg $,$ and the equivalent reactance between the generator E$$ and the infinite bus system U is X$1.$ When a fault occurs at the line, the equivalent reactance between E$$ and U becomes $10$ X$1.$ When the power angle $\backslash$delta $0=60\backslash$deg $,$ the faulty line is cleared, and the equivalent reactance between E$$ and U becomes $1\mathrm{.}5$ X$1.$ When the power angle $\backslash$delta $0=120\backslash$deg $,$ the line reclosure is successful, and the equivalent reactance between E$$ and U returns to X$1.$ Determine whether the system can maintain transient stability after the line reclosure.
