| 摘 要： | 直驱电梯驱动系统产生的电磁干扰是影响系统正常运行的主要干扰源之一,其具有能量大、频带宽、难预测等特点,针对直驱电梯系统的电磁干扰问题,采用多软件联合仿真的方法对电梯驱动系统动力线缆的电磁辐射干扰进行预测研究。通过搭建电梯矢量驱动控制系统,提取直流供电电源的电流作为干扰源,在FEKO电磁仿真软件中建立直驱电梯动力线缆模型,仿真分析了在干扰源作用下电梯内外电场强度分布情况。仿真结果表明,利用多软件联合仿真方法对直驱电梯电磁兼容仿真建模具有工程参考价值。

| Abstract: | Electromagnetic interference produced by direct-drive elevator drive system is one of the main interference sources affecting the normal operation of system. It has great power, wide frequency band and is hard to predict. For direct drive elevator system electromagnetic interference problem, the article adopts multiple software joint simulation method to predict the electromagnetic radiation interference of elevator drive system power cables. Through constructing the elevator vector drive control system, we extract the current of DC power supply as the interference sources, establish the power cable model of direct driving elevator in the electromagnetic simulation software FEKO and conduct simulation analysis of the electric field distribution under the effect of interference sources inside and outside the elevator. The simulation results show that the method of multi-software joint simulation has engineering reference value for electromagnetic compatibility simulation modeling of drive elevator. |
