| 摘要: |
| 双馈风力发电机在国内外的风力发电实际应用中逐渐取代同步发电机和笼型异步发电机，由于风力发电并网时出力的随机波动性，给配电系统的电压无功带来了很大的影响。考虑双馈风力发电机自身的无功输出特点，研究了SVG在其电压无功控制时的应用，详细探讨了SVG并网时的关键技术点，包括控制结构模型、容量的选取以及主要参数的确定。通过IEEE9节点的配电网络数据，在PSCAD中进行实例仿真，验证了所提出方法的有效可行性，为SVG在双馈风力发电系统电压无功控制中的应用提供了依据。 |

| Abstract: |
| Doubly-fed induction generator (DFIG) is gradually replacing synchronous generator and squirrel-cage induction generator in the practical application both at home and abroad, and due to the random fluctuations of wind resources, it brings a big impact to the voltage and reactive power of the distribution network. Considering the reactive power output characteristics of doubly-fed wind generator, the application of SVG in stabilizing node voltage and reactive power control is discussed in detail and key technical points of static var generation (SVG) when connected to distribution network is studied, including control structure model, capacity selection and key parameters determination. With the simulation of IEEE9 distribution network in PSCAD, the effectiveness and feasibility of the proposed method are verified, providing a theoretical and practical value for the widely application of DFIG in the distribution network. |
