Xiaomin Wang · 2015
Generator parameters are key factors for the calculation correctness of the power system simulation. In order to improve the correctness of generator parameters and aiming at the lower precision disadvantage of graphing method in generator parameters identification,a generator parameters identification method based on load rejection method and BPA simulation is proposed. Based on the principles of load rejection method,a field d/q axes load rejection test of a certain generator is carried out,and the simulation modal with same operation status of load rejection test is built by BPS software. By the comparison analysis of simulation result and field test,the d,q axes parameters of the generator is identified. Simulation results show that parameters identified by the proposed method are practical and have higher precision.
