摘　　要：采用矢量控制的变频调速技术和ＰＬＣ改造老式电梯的电气控制系统，提高了电梯运行的可靠性和舒适感，实现了节能降耗，具有现实意义和推广价值。探讨了系统结构设计、变频器容量及制动电阻选择和速度控制曲线等问题。Vector-controlled variable frequency drive and PLC are used to reconstruct the electric control system of demoded elevator. Improved reliability and comfort are achieved. It could contribute to save energy and deduce wastage and has a realism significance and popularize value. This paper discusses the design of the system tructure, the selections of inverter capacity and braking resistor and the controlling graph for speed.
