大型火电厂辅助车间控制系统改造方案设计与实现

针对国华舟山电厂二期已经存在的各辅机系统相互独立的现状,对现场分布的各控制子系统进行分析,提出辅控网改造原则和三层网络分层,针对各辅助车间控制系统提出集成方案。阐明辅控网的组网规约并总结了实施过程中的注意事项。

In view of the fact that each auxiliary machine system of Guohua Zhoushan Power Plant is independent of each otherin the second phase of the power plant, the control subsystems distributed in the field are analyzed, and the principle of reconstruction of auxiliary control network and the layering of three-layer network are put forward. An integrated scheme is proposed for eachauxiliary workshop control system. The network protocol of the auxiliary control network is expounded and the matters needing attention in the process of implementation are summarized.
