摘　　要：长距离大功率输电系统，在暂态时阻尼特性较差是其稳定性的主要特点。本文从理论上论证了静止无功补偿器（SVC）能够提高系统阻尼特性的原理，证明了SVC采用频率作为控制信号时具有最佳的阻尼效果，给出了SVC模型。实际500kV长距离输电系统仿真计算所得的结果验证了SVC提高系统阻尼特性的效果。The poor damping characteristic during transient process is the main character of long distance highpower transmission system. In this paper, it is theoreticallyexpounded and proved that the damping characteristic ofpower system can be improved by use of SVC, and that using frequency as the control signal the damping effect couldbe the best. The effect of improving system damping characteristic by use of SVC is tested and verified in the simulation of a real long distance 500kV transmission system.
