异步电机效率测控与SR电机系统_孙冠群著_9787301368145

本书首先对广泛应用的异步电机的效率问题展开论述，包括：基于光伏供电的水泵异步电机最大功率点和最小损耗点跟踪控制，超大型水泵异步电机高效设计与实验问题，采用多目标进化算法和细菌觅食算法的异步电机现场效率测算方法，采用高阶滑模控制的异步电机可变损耗测控方法，复合跟踪控制的异步风力发电机等。对于前景广阔的开关磁阻电机，主要针对其功率变换及控制问题展开讨论，包括：开关磁阻电机高速运行下转矩控制，作为高速风力发电机时功率变换器设计和连续导通、最大功率点跟踪控制问题，开关磁阻电机初始转子位置估计方法，典型功率变换器的故障诊断方法，作为变速风力驱动下开关磁阻发电机的多种新型功率变换器设计和最大功率点跟踪控制方法等。转矩脉动问题一直是困扰开关磁阻电机和无刷直流电机应用的大问题，本书分三个主题针对开关磁阻电机和无刷直流电机的转矩脉动抑制问题进行了讨论。最后，聚焦海上风电场全直流电能汇聚设计及其经济性问题，提出了一种直流混联矩阵风电场拓扑结构，并进行了成本-效益分析。本书可供从事电机系统效率和开关磁阻电机系统等方向研究工作的科研人员、研究生，以及电机企业工程技术人员参考。
