摘　　要：针对双馈风电变流器常用的集中式控制系统信号处理过于集中、易受干扰等缺点,设计了一种能提高抗干扰能力的分布式控制系统。介绍了分布式控制系统总体构架、各分布式单元功能和光纤通信协议、转子侧和网侧分布式控制策略,分析了其增强抗干扰能力的原因。给出了变流器的主电路拓扑结构,并对变流器进行了长期运行试验,验证了变流器和控制系统的可靠性与性能,给出了部分运行波形。Aiming at demerits of signal processing being excessively concentrated and easy to be interfered of the common centralized control system of doubly fed wind power converter, this paper designs a kind of distributed control system which is able to improve anti-interference capability. It introduces overall architecture of the distributed control system, function of each distributed unit, communication protocol and rotor side and grid side distributed control strategies. Meanwhile, it analyzes reasons for enhancing anti-interference capability. In addition, it provides main circuit topology structure of the converter and introduces long-term operation testing for the converter. The result verifies reliability and performance of the converter and control system. Meanwhile, it provides part of ooerational waves
