曳引式电梯的运行状态与能量的转化和处理

首先利用模糊理论中的隶属度对电梯负载概念进行了拓展，分加速、匀速、减速3种情形分别对电梯运行状态进行了分析。然后针对电梯运行过程中发生于电网、电梯及其承载物之间的能量流动与转化情况，根据电梯曳引机的两种工作状态分别进行了深入讨论，揭示了能量在3者之间的流动与转化规律。最后总结了电梯在其运行过程中产生的再生能量的3种处理方法（即转化、存储和回馈），并比较了各自的优缺点以及在电梯中的应用情况。

Running Case of the Traction Elevator and Its Energy Transformation

This article analyzes the running of elevator from the accelerating case, the uniform speed case and the slowdown case, which the loading concept is expanded with the affiliate degree of the fuzzy theory. In allusion to the energy flow and energy transformation among the power grid, elevator and loading, it discusses two cases of the traction machine, and points out the law of the energy flow and the energy transformation. Finally it summaries three ways for the regeneration energy （transformation, storage and feedback） and their application.
