中压异步电动机的全压起动分析

Analysis of Full Pressure Starting of Medium-voltage Asynchronous Motor

伴随着石化行业大规模的迅猛发展,越来越多的大功率电动机被应用到项目之中,因石化行业对电网运行的稳定性、可靠性及安全性有较高的要求,由此进行严谨的电动机起动分析计算,合理地选择电网配置和起动方案尤为重要。本文结合某在建石化项目,对中压异步电动机的起动进行计算,通过ETAP软件模拟对起动方案进行了分析与比较。

Along with the rapid development of the petrochemical industry,more and more high-power motor is applied to the project,because the petrochemical industry to power grid operation stability,reliability and safety has high requirements,the rigorous motor starting analysis and calculation,reasonable choice of power grid configuration and starting scheme is particularly important.Based on a petrochemical project under construction,the start of medium voltage Asynchronous motor is calculated,simulated and the start scheme is analyzed and compared by ETAP software.
