The problem of subsynchronous resonance (SSR) may be caused by large‐scale wind power transmission through series compensated transmission system.This study discusses the problem of synchronous resonance in Guyuan, Zhangjiakou, and summarises the regularity of the SSR characteristics with the seasons and analyses the reasons.The results show that the regional load has a significant effect on system damping. On this basis, the influence of different load size, load type and different access points for load on SSR characteristics have been analysed, Also typical SSR phenomenon in Guyuan has been reproduced by time‐domain simulation. This study provides a new way to enhance the system damping and reduce the SSR risk from the grid operating point of view.
