With the continuous development of long-distance transmission system and the large capacity generators constantly in operation in the power grid, power system is developing towards the direction of the large joint power system, due to the power grid scale, running more and more complex, the grid security stability problem is more and more prominent. This article in view of the synchronous generator excitation control of power system and parameters on the local stability analysis of power balance, and to ana-lyze its impact on the reliability of the power grid.
