Abstract
Till 2015, a large scale, ultra-high voltage and AC/DC hybrid power transmission configuration, including three ±800kV ultra-high voltage DC systems, will be formed. Eigenvalue and eigenvector of the system are calculated using the eigenvalue analysis method of multi-machine, information of oscillatory mode, such as damping ratio, correlation ratio, right-eigenvector and participation factor, are given under weak damping. Oscillatory modes correlated with sending system Yunnan power network are mainly analyzed, whose modal graphs of right-eigenvector are described. Effective measures to enhance system's dynamic stability are proposed in this article, which is instructive for the planning of 2015 ultra-high voltage and AC/DC hybrid power transmission system.
