| Abstract: | The paper confirms model framework and parameters those need to be identified and researches the identifiability of the excitation system parameters of synchronous steam turbine generator unit by throwing light to the analysis of typical excitation system. The conclusion shows that the parameters can be uniquely identified in fixing model by setting up right observation point. The parameters are acquired through evolutionary strategies in the way that uses error square sum. An example is used to validate that parameters can be effectively identified, and that the parameters are unique. It establishes theoretical foundation for exciting system parameters identification of synchronous steam turbine generator. |
