【摘要】 本文在对国内外旋转电机和直线电机的测试系统概述的基础上,提出了一种用于直线电机轨道交通系统研究的直线感应电机牵引能量互馈试验平台。该平台由提供直流电压的脉冲整流器和两套“变流机组-直线感应电机”组成,一套工作于牵引状态,一套工作于负载模拟状态,两台电机的能量在直流侧互馈。该互馈试验平台具有结构简单、控制灵活、高效节能、试验功能强大等优点,是直线感应电机驱动轮轨交通系统的有效研究平台。更多还原

【Abstract】 Based on the summarize of test system of rotary motor and linear motor, the paper presents a kind of reciprocal power-fed linear induction motor (LIM) drive test rig applied to LIM driven urban rail transit system. The test rig consists of a 4-quadrant converter and two sets of nverter-LIM? One works in the traction state, the other works in the load emulate state. Power is reciprocal in the DC link. The test rig has many merits such as simple structure, flexible control strategy, high efficiency, power saving and powerful test function. As a result, it is an effective research platform of LIM driven wheel-rail transit system.更多还原
