论文摘要
随着风力涡轮机穿透的稳定增长，网格互连的调节标准正在发展，以要求在此类事件中乘车系统乘车系统的乘车系统（例如故障和支撑网格）。对乘坐乘车的偶发性感应产生（DFIG）结构的常规修改导致对故障事件期间对涡轮轴和电网电流的控制有限。与网格连接平行的串联连接网格侧转换器的DFIG架构显示，通过功能处理能力不佳，但电源处理能力较差。在本文中，提出了采用平行网格侧整流器和串联网格侧转换器的统一DFIG风力涡轮机架构。这两个转换器的组合可以使无限制的电源处理和改进的电压干扰骑行。开发了该统一体系结构的动态模型和控制结构。使用计算机模拟说明系统的操作。
With steadily increasing wind turbine penetration, regulatory standards for grid interconnection are evolving to require that wind generation systems ride-through disturbances such as faults and support the grid during such events. Conventional modifications to the doubly fed induction generation (DFIG) architecture for providing ride-through result in limited control of the turbine shaft and grid current during fault events. A DFIG architecture in which the grid side converter is connected in series as opposed to parallel with the grid connection has shown improved low voltage ride through but poor power processing capabilities. In this paper a unified DFIG wind turbine architecture which employs a parallel grid side rectifier and series grid side converter is presented. The combination of these two converters enables unencumbered power processing and improved voltage disturbance ride through. A dynamic model and control structure for this unified architecture is developed. The operation of the system is illustrated using computer simulations.
