励磁控制对电力系统稳定性及电网可靠性分析

Excitation control of power system stability and reliability analysis of power grid

随着远距离输电系统的不断发展以及大容量发电机组在电网中不断的投入运行,电力系统正朝着大型联合电力系统的方向发展,由于电网规模扩大,运行越来越复杂,电网安全稳定性问题越来越突出。本文针对同步发电机励磁控制下的电力系统及参数对电网平衡点的局部稳定性分析,并分析其对电网可靠性的影响。

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.
