Abstract
Trajectory sensitivity is a mathematical tool to quantitatively describe the influence on the dynamic behavior of the power system, it contains a wealth dynamic information of power system. In this paper, it is studied the relations between sensitivity of power angle to fault clearing time and transient stability of power system, established the index system that quantitative assessment the transient stability of generator and whole system in the center of inertia (COI). Case studies are carried out on the one-machine-infinite-bus(SMIB) system and 10-generator 39-bus New England test power system, some results are reported to verify the monotonicity and effectiveness of the index. In comparison to the index of trajectory analysis method, the index provided in this paper accurate evaluation of the transient stability of generator and whole system, also the transient stability should be calculated for only once, it don't need to establish the energy function, the calculation more simple and has a better applied cost.关键词
