描述

PB4-DY
针对线路长出故障和易出故障的地点进行有计划有重点的巡视,一旦发现线路故障要及时处理防止出现跳闸事件影响电力的稳定运行。一般来说电路巡线人员要具备以下几点要求:首先,要具有良好的身体素质,因为无论酷暑还是严寒甚至台风、暴雨天气,巡线人员都需要对供电线路进行安全巡视,所以身体素质的好坏直接影响巡查的质量;其次,巡线人员要具有高度的责任心,只有巡线工作保质保量进行,才能确保故障的及时发现并处理;再次,要敢于直面问题,当供电现场发生临时故障,有时是可以直接指出并加以制止,使故障可以在第一时间被排除。总之,无论在任何情况下都要随机应变,要把尽快解决故障确保供电线路安全稳定运行放到第一位。线路发生故障的原因有很多种,有环境因素导致的、有不可避免的工程遗留问题导致的,因为故障原因的多样化,所以电力巡线人员在巡视中就更要认真仔细,尽最大力量排除电力隐患。

先介绍几点经验。
1、先通读一遍“系统手册”(不管能不能看懂,先了解个大概,以便学习编程时查找);
2、由位控逻辑入手,逐渐增加定时、计数等条件,把或、与、非关系理顺;
3、进而练习整数运算、实数运算、类型转换;
4、量程转换、PID调节回路的建立及P、I、D参数的理解(最好是有个物理回路验证,比如变频器+电机+测速传感器);
5、循环、顺序、跳转等程序控制(尽量避免跳转,非跳不可时也是跳的越近越好);
6、中断、通讯、位置控制....

本人以ABB工业机器人配件DSQC系列和Motorola MVME系列,GE 卡件 模块 驱动器系列为主攻。各位电工朋友可根据自己的条件选择适合自己的PLC品牌,由于PLC的基本框架大同小异,学会一种至于其它的学习起来也就简单了。
