摘　　要：为提高电网的输送能力,电力系统中大量采用了串联电容补偿技术,但串补设备投运后可能产生的次同步谐振(SSR)问题引起了广泛关注。附加励磁阻尼控制(SEDC)是抑制SSR的措施之一。从SEDC抑制效果及对常规励磁系统特性的影响等方面,对SEDC技术进行实验研究。并结合500kV串补装置与上都电厂SEDC装置的联合调整试验,仿真研究了SEDC装置投运后电力系统的稳定特性。The technique of series capacitor compensation had been applied recent years to improve transmission ability of power grids. Subsynchronous resonance （SSR） between the rotor shaft of a generator and the power network in a series capacitor compensated transmission project had been paid a high attention widely. Supplementary excitation damping control （SEDC） was proved an approach to inhibit SSR. Firstly, SEDC＇ s inhibiting ability and its interaction with AVR characteristic were tested. Then, combined with the union test of 500 kV capacitor compensation and SEDC in Shangdu power plant, power system stability after SEDC put into operation was simulated.
