Design and Research on Energy-saving Escalator Based on Multi-stage Driven Frequency Control

Zhang Zhifu,Zhou Chaochao,Wu Wei,Tan Yuying,Sun Ke,Chen Dingfang,Liu Youyuan  
Aiming at the problem of serious energy consumption of the escalator,the paper puts forward the multi-stage drive and frequency control technology to provide the drive force for the escalator.The closed speed feedback is adopted for controlling and regulating the start and stop of various motors to realize normal operation of the escalator;with the cost and total power consumption as the objective functions,the bi-objective optimization is performed for quantities of ordinary three-phase motor and variable-frequency motor through Matlab.The analysis for variation trend of total power consumption and energy-consumption calculation are performed for the escalator by theoretic calculation and Matlab simulation,with the statistical comparison of energy-consumption among different types of escalators by SPSS,which shows that the above-mentioned escalator is provided with excellent energy-saving effect and certain promotion significance.
