燃煤发电机组水力除渣PLC监控系统的设计与实现

Design and Realization of PLC Monitor System in Water Power Slag Handling of Fossil-fired Units Power Plant

介绍了ABPLC5／I4OC可编程控制器（PLC）AControlNet网在2x300MW燃煤发电机组水力除渣控制系统中的应用。该系统在硬件结构上采用上位机双机监控，下住机PLC双机热备形式，并重点讨论了下住机双机监控、双机热备及ControlNet网的实现。实践证明，该系统能够有效地实现对水力除渣过程的自动监控，安全可靠，自动化程度高。

The application of AN PM5/L40C and Control Netin water power slag handling monitor system of 2 X 300 MWfossil-fital units power plant is introduced . The hardware ofthe system is composed of two industrial compuers and lowerredundan hot-backup. Using hot-backup PLC and ControlNet is the distinguishing feature of the system and it's de-sign is discussed in detail- The practice shows that the sys-temm can control the water power slag handling efficiently andhas a high degree of automation, reliability and safety.
