摘要
电力工程一般都采用人工和机械混合的敷设方法对大截面、长距离的110 kV及以上高压电力电缆进行敷设,但总体工作效率不高。本文研发了一套高压旧电缆自动化回收装置解决施工安全可靠快速问题。回收过程中牵引力特性呈现从大到小特点,回收速度定速运行在初始阶段有可能会对电缆有一定破坏作用。为了有效地抑制伺服电机启动时对电缆的冲击,本文提出了基于速度运行曲线的回收装置控制策略。该策略优点是速度随着牵引力柔性变化,改变了电缆恒速控制的传统模式。本文将实际常见的回收场景进行等效,搭建了PMSM(伺服永磁同步电机)矢量控制模型,研究了不同场景的速度曲线控制方式,结合现场条件开展了型式试验测试,验证了控制策略有效性。
Manual and mechanical methods are employed to lay large cross-section and long-distance high-voltage cables of 110 kV and above levels in electric power projects,but the overall work efficiency is not high.The paper introduces a waste high-voltage cable automatic recovery device to solve the problem of safe,reliable and fast construction.In the recycling process,the characteristics of the recycling traction show from large to small,and recovery speed runs at a constant speed may have a destructive effect on the cable in the initial stage.To effectively suppress the impact on the cable when the servo motor starts,the paper proposes a control strategy for the recovery device based on the velocity running curve.The advantage of this strategy is that the speed changes with the flexibility of the traction force,which changes the traditional mode of cable constant speed control.In the paper,the actual common recovery scenes were equivalent,the servo permanent magnet synchronous motor vector control model was established,the velocity curve control modes of different scenes were studied,and the effectiveness of the control strategy is verified.
