超超临界燃煤机组DCS系统控制安全的设计与实现

Design And Realization Of Security DCS In Super-supercritical Firepower Generator Units

分散控制系统(DCS)广泛应用在大型火力发电厂的控制系统,对于控制要求具有控制集中,功能要求复杂多样的特点,因此在DCS系统功能实现的同时,也需要保证DCS控制安全的可靠性。江西某电厂2x1000MW超超临界燃煤机组采用的是杭州和利时公司的HOLLiAS MACS V6.5系列控制系统,本文通过对系统的配电、接地、网络结构特点作了详细介绍和分析,为其他工程DCS系统应用提供借鉴。

Distributed control system （DCS） has wide applications in large thermal power plant. Specifically, it has urgent demand of DCS control security due to the requirements of centralized control and multiple functional. The automation control system of 2 ×1000MW Super-supercritical thermal power generating units in Jiangxi is provided by Hangzhou Hollysys CO.,LTD. This paper thoroughly discusses the distribution, grounding and network of power system, which can provide as a reference for other engineering application.
