142D7274G3驱动器

软件使用公司程软件进行编程，实现系统中的各种逻辑控制功能互锁保护功能。下位机软件由于系统对测试的实时性可靠性要求很高，我们在下位工控机中采用了系统，并使用进行编程。主程序在开始运行后先关中断，读取相关的配置文件，进行初始化，然后开启中断功能并一直循环工作。程序中有两个中断服务子程序，一个用于处理实时测量速度加速度，另一个用于处理与上位工控机的串口通讯。在测试过程中并不对下位工控机进行操作，程序提供的键盘操作主要用于调试检修。同时下位工控机是装在机柜中，也不提供显示器，为防止因误操作出现死机现象，采用了看门狗技术。

　　我们采用测速方法测量车速，保证了在不同的车速下都能达到较高的测试精度，在此基础上得到加速度信号，计算出应该给定的阻力值并通过至上位机。这样下位机根据定制好的协议包将速度，加速度，油耗，阻力通过串口传输给上上位机软件部分的实现上位机接受下位机传上来的车辆当前速度加速度油耗量并对其进行监控。同时将下位送上的实时的阻力值通过传输给用以控制变频器根据实时速度一阻力曲线模拟道路阻力这里我们选用组态软件。其优点是支持硬件，完全基于对象的开发环境，内嵌脚本语言，更易于用户开发，以为核心，轻松地实现监控，测试及人机交互的功能。

采用带速度反馈的闭环矢量控制模式速度反馈用旋转编码器使系统具有足够的调速硬度和良好的低频转矩特性，满足起升机构位能性负载的第四象限运行要求。即使在H时起升电机也能以额定转矩输出。实现恒转矩调速，轻载时可运行以上，实现恒功率调速。控制门机起升机构的关键是要解决低速起动力矩大，下放时制动力矩大和速度平稳调节。所以矢量控制这种面向转矩的控制方式特别适用于门机的起升机构，而且变频器的输出功率是逐渐变化的，可以实现平滑调速也有利于准确定位。因此，我公司选用性能优良的矢量控制变频器。

　　选用变频器时再生制动能量如何处理也要考虑矢量控制变频器中，对再生制动能量的处理方式有两种一种是用制动单元和制动电阻来吸收另一种是通过在直流侧设置可回馈变频器使制动能量回馈到电网。采用把再生制动能量消耗到制动电阻上的方法，设备前期投资较少，安装简单，拆除原起动电阻柜。安装变频器制动电阻即可。但它把再生制动有馒白白消耗在制动电阻上，不利于节能节电我公司本着环保第一的原则选用了价格较贵的可回馈变频器。虽然前期投入较大，但节约了大量电力，从我公司门机改造项目采用变频设备后的能耗测试结果看，整机每年节省电费吕万多元效果分析采用变频器和可编程控制器组成的门式斗轮堆取料一机起升机构调速系统，不仅可以明显提高门式斗轮堆取料机的险可靠性。提高装卸效率降愉挂源消耗降低维修费用减少劳动强度。在改善门式斗轮堆取料机钢结构一的性能二该起升机构调速系统具有良好的低速性能，加减速时间的设定，实现零速抱闸全速受控，减少抱闸闭合时的振动及制动片磨损，可解决门式斗轮堆取料机起升机构起制动的冲击，使门式斗轮堆取料机起升机构的速度变化连续，运行平稳，使得门式斗轮堆取雏月机起升机构减少了加速和减速时的冲击。

LCR滤波器在电机与变频器之间安装LCR滤波器可以改善变频器输出电流和电压的波形，减少电机振动与噪声，并降低射频干扰。必要时可在接触器线圈上并接阻容吸收装置（浪涌吸收器）。抑制电磁污染的选配件应当根据变频器使用环境、对限制电磁干扰（电磁兼容性）的要求而合理选用。

　变频调速系统的抗干扰措施。正确选用控制电缆变频器外部控制可分为模拟信号、数字信号、24VDC电源输出和继电器输出信号<特殊情况下也可采用光纤通信），控制电缆的选用直接影响到系统的抗干扰能力。因此控制电缆好选用屏蔽电缆：低压数字信号线可选用单屏蔽双绞线电缆；模拟信号的传输线、脉冲编码器的信号传输线应当选用双屏蔽的双绞线电缆（笔者有在应急情况下，将用于脉冲编码器信号传输的双屏蔽双纹线电缆与变频器输出屏蔽电缆短距离共管敷设的成功经验）。

由于长期的误解，目前对获取准确参数的研究大大落后于对模型和方法的研究。因此在获取准确参数上下大力气。从事故重现不准的教训中得出的宝贵认识。在具体做法上，WSCC要求所有安装在其电网上的容量超过6MW的发电机组的控制系统参数全部实测。这项工作正在展开。

　　控制系统参数十分重要当WSCC动态数据库不能重现1996年8月10日的故障时，研究人员修改了仿真中使用的模型，在加入了AGC模型和直流输电控制模型，修改了汽轮机调速器模型和电压控制模型后，仿真得到的系统频率和电压变化曲线与实测曲线便比较接近了，但仍不能从仿真中得到系统振荡。后修改了功率送出端（加拿大侧）的负荷模型，即从静态指数模型改为动态电动机模型，或从指数模型改为恒功率模型后，振荡就可以从仿真中得到了。

　　负荷模型何以能起到这么大的作用这是在控制系统的帮助下实现的。本来在功率送出端负荷模型从指数模型改为恒功率模型时应该是有利于稳定的，因为恒功率模型比指数模型能吸收更多的功率。但事故分析中的结论却正好相反，这是由于通过PSS参数整定错误造成的。
