A method for analyzing and evaluating the dynamic regulating performance of excitation system using dynamic electrical data of generator unit and its excitation system acquired by phasor measurement unit （PMU） is proposed based on synchronized phasor measurement technology. Combined with an engineering processing of corresponding excitation system performance parameters, the method realizes the calculation and analysis of the main excitation system performance indexes through detecting and extracting the course of a generator unit disturbance and its excitation system response. Meanwhile,. its whole sottware system functions are designed and realized based on the system structure of a WAMS. The method introduction and practical project applications show that compared with conventional analysis methods, this method has the advantages of online analysis, offline research, simplicity, practicality, and convenience and its computed results can be taken as an important reference for the evaluation of dynamic regulating performances of an excitation system.
