| 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5001kV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.

| Abstract: | The technique of series capacitor compensation had been applied recent years to improve transmission ability of power grids. Sub-synchronous 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 ca-pacitor compensation and SEDC in Shangdu power plant, power system stability after SEDC put into operation was simulated. |
