Abstract


  • http://www.aupec09.eleceng.adelaide.edu.au/

    This paper presents the linearised small-signal dynamic modelling of hydroelectric turbine-generator (TG) unit with CIGRE first high-voltage direct current (HVDC) benchmark system in the synchronously rotating D-Q reference frame for small-signal stability analysis. The interaction behaviour between the hydroelectric unit and the dynamics and control of HVDC system is investigated utilising eigen-analysis,

    participation factor analysis and by conducting sensitivity studies. The computation of eigenvalues and eigenvectors for small signal stability analysis provides an invaluable insight onto the power system dynamic behaviour by characterising the damping and frequency of the system oscillatory modes. The

    consequences of different operating conditions, such as active and reactive power variations, the variation of generator-toturbine inertia ratio, as well as the changes of HVDC constant current controller parameters on small-signal system stability are investigated.
