中文摘要	A load parameter identification method based on synthetic wide-area signals is presented, which takes generator relative angle as wide-area signals to synthetically analyze its trajectory sensitivity to load parameters. The sensitivity analysis results are used to select the generator angle and favorable fault location for load parameter identification, and to determine the identifiability of each load parameter. The wide -area load parameter identification is realized by minimizing the objective function of the least-squares fitting of generator angle response curve, obtained from estimated load parameters, to real generator angle curve. The simulative analysis of a 10-machine 39-bus system shows that, the generator angle of Unit 30 should be selected as wide-area signal and the favorable fault location is Bus 19; the load ratio of induction motor and the impedances of stator and rotor are parameters with high sensitivity and more easily identified. The parameters identified by wide-area identification reflect the real system dynamic performance more precisely for various operation and fault conditions.
