One of key means on study coupling relationship between hydraulic system and electromechanical system is that build the corresponding relationship between guide vane motion and disturbance occurred by hydro turbine generating units and power network, that is called as tracking response characteristics of guide vane. This paper analyzes the basic characteristics and mathematic model of guide vane motion based on classic structure hydro turbine generating units model, in which include governor, excitation controller, hydro turbine and generator, and simulates guide vane motion in practical operating. At last, the active power regulations are simulated. According to simulation curves, build tracking response model of guide vane to active power regulation, and define tracking characteristic coefficients and give its calculation method. Simulation results show that proposed tracking model has well self-adaptive ability due to include basic motion characteristics and is effective. © 2011 Published by Elsevier Ltd.
