摘要

研究了双馈风电机组加入惯量控制后对系统小干扰稳定的影响。首先，分析了双馈风电机组为系统提供惯性支持的基本原理，讨论了两种惯量控制的方法。然后，分析了这两种控制方法对系统小干扰稳定的可能影响。最后基于仿真，用模式分析法分析了不同控制策略和参数下的惯量控制对系统小干扰稳定的影响特性。分析表明，引入惯量控制对系统的小干扰稳定存在较明显的影响，在设计控制方法和参数时需要考虑小干扰稳定的安全约束。

Abstract

The impact of inertia control of doubly-fed induction generator（DFIG）wind turbines on the small-signal stability of systems is studied.Firstly，the principle of DFIG wind turbines offering inertia responses is discussed，followed by the introduction of two approaches of inertia control.Then，possible influences of two control schemes on system small-signal stability are analyzed.Finally，on the basis of simulation，the modal analysis method is adopted to analyze the influence characteristics of different control strategies and various control parameters on system small-signal stability.Analysis results show that inertia control may have an appreciable impact on the system small-signal stability.Therefore，security constraints of small-signal stability should be carefully considered when designing the control strategy and parameters.
