Abstract

Based on an advanced distributed real-time platform named Real-Time Laboratory (RT-LAB), the impacts of the static synchronous compensator (STATCOM) on wind power system dynamics is studied in this paper. Firstly, a small-scale wind farm model based on squirrel-cage induction generator (SCIG) is built in MATLABTM/Simulink environment. This model is then rebuilt to be suitable for the real-time operation mode in RT-LAB environment in terms of the operating requirements of RT-LAB. The corresponding comparisons of simulation results carried out in RT-LAB and MATLABTM/Simulink environments respectively demonstrate that it is applicable for wind power system to implement realtime simulation in RT-LAB environment. Finally, the STATCOM device is connected to the power grid. And the comparisons of real-time simulation results of the wind power system with and without STATCOM connected illustrate that the integration of STATCOM can improve the voltage stability of the system.
