摘要

采用耦合电路模型分析了直线感应电动机的暂态和动态特性。研究了在故障条件下，连接逆变器电源的LIM在加减速过程中对阶跃频率变化的响应，以及在滑差频率控制下的行为。文中还分析了钢轨顶盖电导率的变化和气隙的动态变化所引起的LIM参数变化及其瞬态特性。在各种瞬态条件下，对推力、速度和次级片电流进行了评估。计算机模拟结果与实际lim的测试测量结果进行了比较。

Transient and dynamic performance of a linear induction motor

A coupled-circuit model is used to analyze the transient and dynamic performance of a linear induction motor (LI). The behavior of a LIM during acceleration and deceleration, under fault conditions, in response to a step frequency change when it is connected to an inverter supply and under slip-frequency control is studied. The LIM parameter changes and the consequent transient behavior brought on by changes in rail top-cap conductivity and dynamic changes of the air gap are also presented. The thrust, speed, and secondary sheet currents are evaluated under various transient conditions. Computer simulation results are compared to test measurements from operational LIMs.<>
