在风电场内,风电机组变流器控制参数设置不当可能会引发该机组及其他机组的功率振荡,威胁电力系统的正常运行。为了研究变流器控制参数对风电场内机组振荡的影响,以双馈风电机组为例,首先考虑变流器控制参数推导机组的能量函数。然后,分析变流器控制参数对机组能流功率和能量消耗的影响。接着,针对风电场内机组变流器控制参数的不同,研究风电场内机组是否会发生振荡以及对其他机组的影响。最后,在PSCAD/EMTDC平台上建模,深入分析了变流器控制参数对风电场内机组能流功率和能量消耗的影响。结果表明:在风电场内,机组变流器控制参数设置不当不仅会引起本机组发生自由振荡,也会造成风电场内其他机组振荡。
In the wind farm
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.
