针对现有基于阻抗法的双馈风电机组稳定性研究常忽略外环控制
且该处理对稳定性的影响缺乏相关研究的问题
首先
针对双馈风电机组定子-转子侧变换器(RSC)部分和网侧变换器(GSC)部分
建立矢量控制下考虑功率外环控制的双馈风电机组宽频导纳模型。通过与电磁暂态仿真模型对比
验证所提模型的准确性和有效性。其次
基于双馈风电机组制造商提供的参数范围
通过理论分析外环控制参数变化对双馈风电机组导纳特性的影响
发现外环控制的比例参数变化将大大影响双馈风电机组的导纳特性
进一步研究表明忽略RSC外环控制可能导致阻抗分析法无法识别双馈风电场并网系统在不同频段的振荡问题
将实际会发生振荡的系统判断为稳定
从而威胁电力系统安全运行。最后
搭建双馈风电场并网实际算例
通过改变RSC外环控制参数来观察其对系统振荡稳定性的影响
验证考虑功率外环对于阻抗法分析双馈风电机组并网系统振荡稳定性的关键作用。
The outer-loop control is often ignored when using impedance method to solve the stability problem of the grid-connected doubly fed induction generator (DFIG) system. However
the influence of ignoring the outer-loop control on the stability of the system has not been deeply studied. To solve this problem
firstly
this paper proposes a broadband frequency admittance model of DFIG which includes both stator- rotor side converter (RSC) and grid side converter (GSC) with integrated power outer-loop controls. The accuracy and validity of the proposed admittance model are verified by electromagnetic transient simulation model. Secondly
based on the actual operational parameter ranges provided by wind turbine manufacturer
influence of variations in outer-loop control parameters on the admittance characteristics of DFIG is analyzed theoretically. The results demonstrate that variations in proportional coefficients significantly affect the admittance characteristics of DFIG. Further studies indicate that overlooking RSC outer-loop control may hinder the recognition of oscillation problems when using the impedance method in the grid-connected DFIG system across various frequency bands. This may lead to erroneous assessment of an actually oscillatory system as stable system
thereby posing a risk to the safe operation of the power system. Next
a practical example of grid-connected DFIG wind farm is established
and the impact of RSC outer-loop control parameters on oscillation stability is observed by the variation of RSC outer-loop control parameters
which validates the crucial role of incorporating the power outer-loop when impedance analysis is applied for oscillation stability assessment of grid-connected DFIG system.
