摘要

本文对台湾某炼铁企业焦炉厂焦炭转运车的4台28kw感应电机的工作特性和现场测量结果进行了研究。采用铭牌数据和所研究的IMs在各种操作条件下的现场实测响应来获得所研究的IMs的参数。本文讨论并比较了由4个独立的小型变频器驱动的4个IMs和由一个大型变频器驱动的4个并联IMs的实测输出响应。根据启动和稳态条件下的现场实测结果对比,可以得出使用大容量变频器驱动4个并联运行IMs的控制方案比使用4个独立变频器驱动4个相同IMs的控制方法具有许多优点。

Performance analysis of induction motors for driving coke transfer cars of a coke oven plant in a practical iron-making factory
This paper investigates the operating characteristics and field measurement results of four 28-kW induction motors (IMs) that are employed for driving coke transfer cars of a coke oven plant in a practical iron-making company in Taiwan. Both nameplate data and filed measured responses of the studied IMs under various operating conditions are employed to obtain the parameters of the studied IMs. This paper discusses and compares the measured output responses of the four IMs driven by four independent small frequency converters and the ones of four parallel-operated IMs driven by a large frequency converter. According to the comparative field measured results under both startup and steady-state conditions, it can be concluded that the control scheme of using a larger-capacity frequency converter to drive four parallel-operated IMs has several advantages over the original control method of employing four identical IMs driven by four independent frequency converters.
