将公用系统和1#炉的控制器(型号为CP60)升级为新控制器(型号为FCP270)，控制器不再集中布置，升级后的控制器随卡件柜布置。
3、对现有公用系统和#1炉及1#机卡件柜利旧改造，卡件底板更换为最新的FBM底板，原有卡件保留。
4、将工作站全部升级为最新的工作站(型号为H92)，操作员站和工程师站性能将大大提升。
5、公用系统和1#炉及1#机升级完毕后，可根据要求启动公用系统和1#炉及1#机，进行正常生产运行，同时对2#炉、3#炉和2#机进行升级改造，这两个炉在升级后逐一接入新的Mesh网络系统，既保证生产安全，又使得现场停机时间不会太长，保证生产连续。
6、控制系统主要施工步骤
软件部分：
(1) 现有系统软件备份，包括组态、画面、系统定义盘等;
(2) 根据新的系统定义，制作系统定义盘，并使用新的定义盘进行工作站安装;
(3) 现有Unix平台下画面和逻辑转换到Windows平台;
(4) 将系统原有组态以及功能恢复至Windows平台后进行调试以使系统原有功能在windows平台完整保留并且运行正常;
硬件部分：
(1)新机柜安装就位;
(2)电缆光缆铺设，光缆熔接;
(3)新控制器(型号为FCP270)安装;
(4)原有卡件柜改装旧底板拆除，新底板安装，卡件恢复;
(5)系统恢复、上电，检测控制器、工作站及I/O卡件状态，测试DCS各部件工作情况。
五、结论
通过本次的升级改造，使本厂的DCS系统控制器(型号为CP60)升级为新控制器(型号为FCP270)，控制器不再集中布置。工作站全部升级为最新的工作站(型号为H92)，操作员站和工程师站性能将大大提升。解决了原来卡件停产造成备件采购困难的问题，同时通过DCS整体升级改造增加了设备的稳定性，为长时间的稳定连续生产打下良好的基础。groups of triggers are respectively taken from the synchronous transformer corresponding to the rectifier transformer.

When the system is set to zero, the speed regulator ASR and current regulator ACR are locked to zero by the zero speed blocking signal. At this time, the system mainly consists of a constant current system with cross feedback composed of a loop regulator arr. Due to the influence of the given circulating current, the two groups of thyristors are in the rectification state, the output voltage is equal and the polarity is opposite, the armature voltage of the DC motor is zero, the motor stops, and the output current flows through the two groups of thyristors to form circulating current. The circulating current should not be too large, which is generally limited to about 5% of the rated current of the motor. When starting in the forward direction, with the increase of speed
