Analysis of Unit Oscillation in Wind Farm Considering Control Parameters of Converter for DFIG-based Wind Turbine
improper setting of control parameters of the converter for the wind turbine may cause the power oscillation of the unit and other units
which threatens the normal operation of the power system. In order to study the influence of control parameters of converters on the unit oscillation in the wind farm
taking the doubly-fed induction generator (DFIG) based wind turbine as an example
first
the converter control parameters are considered
and the energy function of the DFIG-based wind turbine is derived. Then
the influence of control parameters of converters on the energy flow power and energy consumption of the DFIG-based wind turbine is analyzed. Next
in view of the different control parameters of the unit converter in the wind farm
whether the units in the wind farm will oscillate and the influence of the unit on other units are studied. Finally
the model is built on PSCAD/EMTDC platform
and the influence of control parameters of the converter on the energy flow power and energy consumption of the wind farm is analyzed. The results show that the improper setting of control parameters of the unit converter not only causes free oscillation of the unit
but also causes oscillation of other units in the wind farm.
