摘要

构网型直驱风电机组主要分为有功功率控制型和直流电压控制型，目前，缺乏两类构网型风电机组的稳定性对比。针对上述问题，该文提出一种计及直流侧交互的构网型直驱风电机组的小扰动稳定裕度量化方法，基于幅相频率特性，揭示两类构网型直驱机组机侧、网侧变换器的小扰动交互机理。结果表明，有功功率控制模式的构网型网侧变换器在直流侧呈现出负电阻特性，易与机侧变换器异常交互引发失稳问题；直流电压控制模式的构网型直驱风电机组不存在直流侧交互失稳问题。在此基础上，提出一种镇定控制方法，有效增强了有功功率控制模式的构网型风电机组的稳定性。最后，基于PSCAD/EMTDC平台，验证了理论分析的正确性及所提镇定控制方法的有效性。

Abstract

Grid-forming direct-driven wind turbines can be mainly divided into active power control type and DC voltage control type. At present

there is a lack of comparative analysis about the stability of the two types of grid-forming wind turbines. In response to these above issues

a small-disturbance stability margin quantification method for grid-forming direct-driven wind turbines considering the DC-link interaction is proposed in this paper. Based on the amplitude phase frequency characteristics

the small-disturbance interaction mechanism between the machine-side and grid-side converters of grid-forming direct-driven wind turbines is revealed. The research results indicate that the grid-forming grid-side converter under active power control mode exhibits negative resistance characteristics on the DC side

which can easily interact abnormally with the machine-side converter and cause instability. There is no DC-side interactive unstable issues in the grid-forming direct-driven wind turbine under DC voltage control mode. On this basis

a stabilization control method is proposed

which effectively enhances the stability of grid- forming wind turbines under active power control mode. Finally

grounded on the PSCAD/EMTDC platform

the correctness of the theoretical analysis and the effectiveness of the proposed stabilization control method are verified.
