Research Abstract

In this study, firstly simulation analyzes of transient stability of power system including wind generator during symmetrical and unsymmmetrical short circuit faults are performed. Two shaft system models are used for the wind generator in the simulations, which are one-mass and two-mass shaft models, and an effect of shaft system modeling on the transient stability is analyzed. Based on the simulation results, it is concluded that the transient stability of wind generator system is strongly dependent on the modeling of the shaft system. The two-mass shaft model can give an unstable result though the one-mass model gives a stable result for the same fault condition. Wind generator system with large spring constant of the shaft between generator and wind turbine is transiently more stable during power system fault. Wind generator system with large total inertia constant of generator and wind turbine is transiently more stable during power system fault. Wind generator system having large … More inertia constant of generator is transiently more stable during power system fault. In power system simulations, wind generators are often expressed by a one-mass model for simplicity. However, it is clear from the above conclusions that wind generators need to be expressed by a two-mass model in order to perform exact transient stability analysis.
Next, a new way of stabilization of the wind generator system with doubly-fed flywheel generator (doubly-fed asynchronous machine, DASM) is analyzed. Various simulation results by PSCAD/EMTDC show the effectiveness of preventing the voltage collapse of the wind generators after a short circuit fault with the reactive power compensation from DASM. Comparison studies are also performed between the wind turbine pitch control and the proposed method. The apparent superiority of the latter to the former is validated. It can be said that DASM can be used as a much more effective way to stabilize the power system as compared with conventional pitch control system. It is also found that DASM can be used to provide locally the leading reactive power compensation to the wind generators in the steady state. Simulation is also done on multiple wind generator system when wind power fluctuates randomly. Two typical types of wind speed patterns are used in the study. Both results show the effectiveness of DASM on smoothing variations of output power and terminal voltage of the wind farm when wind power fluctuates. All in all, simulation results show that DASM can be used to minimize the influence to the system under large electrical disturbances in the network and under a severe wind gust effectively. Simulation results also show the effectiveness of DASM in providing locally the leading reactive power compensation to the wind generator in steady state. Less
