基于Sinamics S120小功率城轨模拟牵引系统的设计

Design of Sinamics S120-Based Low Power Urban Railway Simulation Traction System

构建了2.2 kW交流异步电机的城市轨道模拟牵引系统,该系统以西门子PLC S7-300作为控制器,SINAMICS S120作为驱动装置,通过PROFIBUS-DP总线完成各部分之间的通信.实现了在小功率条件下对城市轨道牵引系统运行工况的模拟,并对牵引电机的特性参数进行了采集与分析.

A stimulant traction system of urban railway vehicle with 2.2 kW AC asynchronous motor is designed,using Siemens S7-300 as controller and Sinamics S120 frequency-converter as drive equipment with communacation between PLC and S120 by PROFIBUS-DP to achieve urban rail traction system operating simulation in the low power condition, and the characteristic parameters of the traction motor are collectied and analyzed .
