基于解耦调制方式的共直流母线开绕组永磁电机容错控制
|
摘要
为了实现共直流母线开绕组系统中发生逆变器桥臂开路故障时的容错运行,同时提高容错模式下的电压利用率,根据开绕组拓扑结构的冗余性,提出一种基于中间六边形调制的共直流母线开绕组容错拓扑结构,有效提高了容错运行能力。在此基础上,通过解耦调制的引入,建立2种新型容错拓扑结构与相应的解耦角度的内在联系,提出统一的容错调制策略,在满足不同故障类型容错运行需求的同时,提高了容错运行时的直流电压利用率,拓宽了电机系统调速范围。通过构建共直流母线开绕组系统实验平台,对所提出的共直流母线开绕组电机驱动系统容错控制策略进行实验研究。理论分析和实验验证了所提策略的有效性。
In order to realize fault-tolerant operation of the open winding permanent magnet motor(OW-PMM) with common DC bus under leg open-circuit fault and improve the utilization of the DC voltage, a new fault-tolerant topology based on middle-hexagon SVPWM was proposed in this paper firstly, according to the redundancy of the system. Based on this, through introducing decoupled modulation strategy, the relation between two fault-tolerant topologies and the corresponding decoupling angles was established and the unity fault-tolerant modulation strategy was proposed, which can meet the demand of different fault types. Meanwhile, the utilization rate of DC voltage in the fault-tolerant operation mode is improved and the speed adjustment range of the system is winded. Finally, the fault-tolerant control method of the OW-PMM system with common DC bus was studied experimentally through the establishment of the experimental platform. Theoretical analysis and experimental results verify the effectiveness of the proposed fault-tolerant method.
