摘要
针对传统电梯制动能量浪费问题,设计一套基于能量回馈技术的曳引式电梯节能系统。该系统以永磁同步电机和双向变频器为核心技术,采用超级电容储能,将电梯制动时的再生能量回送至电网或储存循环利用。仿真分析和缩比实验结果表明,该系统在典型运行工况下的综合节能率达到21.1%,回馈能量利用率为89.3%,各项性能指标均达到了设计要求。
Addressing the problem of wasted braking energy in traditional elevators,an energy-saving system for traction elevators based on energy recovery technology is designed.The system uses permanent magnet synchronous motors and bidirectional frequency converters as core technologies,employs supercapacitor energy storage,and feeds regenerative energy from elevator braking back to the grid or stores it for cyclic utilization.The simulation analysis and scaled-down experiment results show that the comprehensive energy-saving rate of the system under typical operating conditions reaches 21.1%,the utilization rate of feedback energy is 89.3%,and all performance indicators meet the design requirements.
