[Energy industry] multiphase_machine_MMF_harmonics DL : 0: 多相永磁同步电机驱动技术研究(中科院博士论文)目前,三相电机驱动系统在电气驱动应用场合得到了广泛的应用,然而随着现代电力电子技术、计算机技术和控制理论的发展,由逆变器供电的电机驱动系统的相数不再受到供电相数的限制。特别在大功率、高可靠性和低直流电压供电应用场合,多相电机驱动系统比三相电机驱动系统更具优势,因此多相电机驱动系统特别适合于应用在舰船全电力推进、电动车辆、航空航天和军事等场合。其相关技术的研究为电气驱动技术的研究开辟了新的领域,多相电机驱动系统得到各国科研人员越来越多的关注和重视。本文研究从任意相数多相电机出发,重点研究了五相永磁同步电机驱动系统,全文主要内容如下: 引入绕组函数理论定量分析了任意相数对称绕组的磁势时空谐波分布,说明了低次时空谐波在多相电机中的重要作用首次从对称分量法推导出推广派克变换,并建立了n-m相感应电机数学模型,指出多相电机控制是一个多维控制问题。这些基础理论知识为分析多相电机奠定了理论基础。建立了五相永磁同步电机派克方程,在此基础上研究了五相永磁同步电机中d-q子空间与广义零序子空间的耦合问题。并根据不同结构形式五相永磁同步电机的特点,详细讨论了不同情况下的多维矢量控制和解耦控制问题。 -In electrical drive applications, three-phase drives are widely used for theirconvenience. However, with the advent of modern power electronics, computertechniques and control theories, the inverter-fed motor drives remove the limitation onthe number of power supplies and machines phases. Especially in the applications ofhigh power, high reliability, and low dc bus voltage, multiphase drives show severaladvantages over three-phase drives.

[Energy industry] Performance-Comparison-of-VSC-Based-Shunt-and-SER DL : 0: In this paper, the performance of voltage-source converter-based shunt and series compensators used for load voltage control in electrical power distribution systems has been analyzed and compared, when a nonlinear load is connected across the load bus. The comparison has been made based on the closed-loop frequency response characteristics of the compensated distribution system. A distribution static compensator (DSTATCOM) as a shunt device and a dynamic voltage restorer (DVR) as a series device are considered in the voltage-control mode for the comparison.
