Hydropower unit model identification using the field data

摘要

A model identification method of hydropower unit (HU) based on Auto-Regressive and Moving Average (ARMA) has been proposed. The ARMA model coefficients were obtained by least square method. Using the proposed method, the parameters e_y, e, and e_(qh) of hydro turbine can be calculated. Experiment results show that the model identification simulations were consistent with the measured data of field tests.
