介绍某火电厂3号机汽轮机数字电液调节系统(digital electric hydraulic control system,DEH)由原西门子PSC7系统改造为新华 XDPS400+系统及分散控制系统(distributed control system,DCS)使用西门子 TXP 控制系统后,为了实现DCS与DEH一体化监控方式,TXP 控制系统侧采用 CM104通信器作为虚拟控制器,通过Modbus通信协议与 XDPS400+系统实现通信连接,从 DCS 侧对 DEH 进行参数监视和操作控制,为此,说明两系统间通信硬件的冗余配置连接方式、Modbus 通信协议的原理、CM104通信器的软件初始化文件的配置、CM104通信器的工作原理、DCS通信功能块组态以及两系统间通信实现的原理。最后详细介绍调试、初运行过程中存在的问题与解决方法。

Siemens PSC7 system formerly adopted as digital electric hydraulic control system (DEH)in steam turbines of units No.3 in a thermal power plan/t is replaced by XDPS400+ system and distributed control system (DCS)that adopts TXP control system manufactured by Siemens.To implement integrated monitoring of DCS system and DEH system,CM 1 04 at TXP control system side is adopted as virtual communicator and connects to SDPS400+ system via Modbus communication protocol to implement DEH parameter monitoring and operation control at DCS side.Therefore,the paper expounds redun-dancy configuration connection mode between communication hardware of the two systems,principle of Modbus communi-cation protocol,configuration of software initialization file of CM1 04 communicator,work principle of CM 1 04 communica-tor,configuration of communication modules of DCS and principles of communication implementation between the two sys-tems.In the end,the paper elaborates on problems and solutions during debugging and initial operation.
