Study on the oscillation characteristics of doubly-fed wind turbine considering the variation of operating parameters in microgrid
To study the coupling and oscillation characteristics of power equipment in microgrid
the energy functions of the wind turbine subsystem
generator and excitation subsystem in the doubly-fed wind turbine are deduced based on the transient energy flow method taking into account the wind speed and the control strategy of the unit. Then
the mechanism of the change of the energy consumption of each subsystem is investigated when the wind speed
the control parameters of the unit and other operational parameters change
and the oscillation characteristics of the unit are analyzed. Finally
the energy change and power oscillation characteristics of the doubly-fed wind turbine when the operation parameters change are analyzed by modeling and simulation on PSCAD/EMTDC platform
and the results are compared with the eigenvalue calculation results to verify the reasonableness of the analysis. At last
the influence mechanism of wind speed change on the oscillation of doubly-fed wind turbine is obtained.
