When the power system load in a small disturbance, the system itself to maintain the stability of the power transmission capacity, the use of automatic excitation regulator device may reduce the reactance of the generator, and then further to maintain the transformer high-voltage bus voltage constant, so compensation not only its own reactor, but also compensation for the step-up transformer reactance, thus greatly improving the power limits of generators, which greatly increased the static stability of power system.

当电力系统的负载发生微小的扰动时，系统本身保持稳定送电的能力，使用自动励磁调节装置，则可减小发电机的电抗，再进一步维持变压器高压母线的电压恒定，这样不仅完全补偿了自身的电抗，而且还补偿了升压变压器的电抗，这样就大大提高了发电机的极限功率，即大大地提高了电力系统的静态稳定。
