碩士 / 國立成功大學 / 電機工程學系 / 102 / This thesis presents stability analysis of two system configurations using a dynamic-slip induction generator (DSIG). System configuration 1 is a wind turbine generator based on DSIG while system configuration 2 is a two-area multi-machine power system connected with an integrated onshore wind farm based on DSIG and offshore wind farm based on doubly-fed induction generator (DFIG) through a static synchronous compensator (STATCOM). The q-d axis equivalent-circuit model is derived to establish the complete system model under three-phase balanced condition. A lead-lag type of power-oscillation damping controller (PODC) of the STATCOM is designed by using phase-compensation method based on modal control theory to damp low-frequency oscillations of the studied power system. Analysis of steady-state operating characteristics and eigenvalue variation of the studied system under different operating conditions is performed. Dynamic and transient simulations of the studied system subjected to a wind-speed disturbance, a torque disturbance, and a three-phase short circuit fault at the power system are also carried out. The responses of the studied system containing the STATCOM with and without the designed PODC are also compared.
