Abstract
Traditional evaluation methods of performance of excitation system are often carried on offline or need special conditions. To realize monitoring and evaluation of performance of the excitation system in operation, this paper proposes practical arithmetic of monitoring the unit operation status based on PMU measured data. After data preprocessing, using valid data to identify field flashing, de-excitation, load rejection and terminal voltage drop. Then corresponding performance evaluation indexes of the excitation system, respectively under different conditions is calculated . The quantitative evaluation result of the performance of excitation can be obtained and it can provide some reference for the evaluation of the practical operation performance of excitation system.
