Abstract

Special Machines are gaining momentum in high performance drives. Permanent Magnet Synchronous Motor (PMSM) drives are widely employed to take advantage of its distinctive characteristics such as increased efficiency, improved power factor, comparatively lower inertia, high power density and larger torque to volume ratio. To integrate with renewable resources there are many recent inverter topologies. One such topology is popular Impedance Source Inverter (ZSI). ZSI uses a combination of capacitors and inductors (Z-Source network) followed by a conventional VSI. Because of its unique structure, ZSI reduces line harmonics, increases reliability, improves power factor and extends output voltage range. This paper attempts to analyze closed loop performance of conventional ZSI fed PMSM drive with classical FOC with different modulation schemes for pumping applications. Mathematical model of the pump is formulated and its performance is analyzed during simulation. Characteristic curve of centrifugal pump is validated using simulation results obtained.

面向磁场控制泵送用ZSI永磁同步电机驱动器的设计与分析

特殊机器在高性能驱动器方面正获得动力。永磁同步电机(PMSM)驱动器广泛应用于其独特的特点，如提高效率，改善功率因数，相对较低的惯性，高功率密度和较大的转矩体积比。为了集成可再生资源，最近出现了许多逆变器拓扑结构。一种这样的拓扑是流行的阻抗源逆变器(ZSI)。ZSI使用电容和电感(z源网络)的组合，然后是传统的VSI。由于其独特的结构，ZSI减少了线路谐波，提高了可靠性，提高了功率因数，并扩大了输出电压范围。本文试图分析不同调制方案的传统ZSI馈源永磁同步电动机驱动在抽运应用中的闭环性能。建立了该泵的数学模型，并对其性能进行了仿真分析。利用仿真结果验证了离心泵的特性曲线。
