摘要
介绍了地铁电压暂降现状和自动扶梯安全标准要求;论述了电压暂降对地铁自动扶梯运行的影响;研究利用SPWM算法的电力监测与超级电容储能方案,建立对自动扶梯关键部位快速响应输出补偿稳压方式的模型。通过分析某地铁站实践应用的运行成效,表明该方案模型是行之有效的。
The current situation of subway power voltage sag and the safety standard requirements of escalator are analyzed.The influence of voltage sag on metro escalator operation is discussed,and the scheme of electric power monitoring and super capacitor energy storage using SPWM algorithm are studied.The model of fast response output compensation and steady voltage compensation for key parts of escalator is established,and the operational effect of practical application of a metro is analyzed.The results show that the proposed model is effective.
