摘要
本文针对普通电梯变频器不能回馈再生能量的缺点,研制了一台基于幅相控制的15kW外挂式电梯能量回馈器样机,实现了单位功率因数能量回馈和直流母线电压可控。在此基础上,根据电梯起停频繁的特点,利用直流母线电压变化率推导出起动时刻理想初始参数和在输入功率变化时的前馈调节量,提高了系统的快速性。通过在上海三菱电梯有限公司现场实测表明,该回馈器工作稳定可靠,具有良好的动、静态性能。
Considering the disadvantages of ordinary elevator transducer that it cannot utilize the regeneration energy, this paper designs a 15kW elevator energy-regeneration equipment which can connect with elevator transducer easily based on phase and amplitude control. It realizes unity power factor operation and can control input DC voltage. On this foundation, in view of features that the elevator starts and stops frequently, the ideal starting time parameter and the value of feed forward adjustment when input power changes are deduced using the rate of change of input DC voltage and the regulation time of the system is shortened. The test in Shanghai Mitsubishi Elevator Ltd. indicates that the energyregeneration equipment has the advantages of good static and dynamic characteristics.
