IC660BBR101

项目概述：

本网络方案是株洲电厂二期技改工程2×300MW机组采用的辅控“水”网网络控制系统。辅控“水”网包含对以下辅助控制系统的监视和控制：化学补给水控制系统、凝结水精处理控制系统、汽水取样及化学加药控制系统、化学废水处理控制系统1、净水站控制系统、制氢站控制系统。

辅控“水”网向SIS系统提供过程数据和计算、分析结果以满足电厂总值长对全厂生产过程的管理要求，确保机组、运行。

二，网络拓扑：

本方案设计的辅控网络采用双星型网络结构。赫思曼的MACH3002核心交换机作为整个网络的中心，百兆冗余连接到服务器（实时数据库），百兆连接到各终端PLC。

辅控“水”网采用上位机、可编程控制器（PLC）相结合的控制方式, 辅控“水”网覆盖化学补给水系统、凝结水精处理系统、化学取样及化学加药系统、化学废水处理系统、净水站系统、制氢站系统，负责以上各个车间系统的监视、运行操作，上位机主要完成系统所覆盖各车间的设备的操作，各车间系统运行参数的显示、计算、报警、打印以及PLC参数设置、控制逻辑的修改，系统的调试；PLC接收上位机的操作指令完成对被控设备的控制、被控对象的联锁保护，同时将采集到的信号经过处理后通过光纤交换机提供给网络数据库服务器和上位机。台湾的雪山隧道全长总计12.9km，是第五长的隧道，也是亚洲第二长的公路隧道。雪山隧道是一座由多组隧道构成的隧道群。除了东行线、西行线的两座主隧道，尚包括中间的导坑；两座主隧道中间，有28座横向的人行联络隧道、8座车行联络道，加上抽排风系统所挖掘的竖井、三处通风站、三座通风中继站合计112处横向通风隧道、六座通风竖井及一号竖井顶部排风用横向排气隧道等等，大大小小长长短短共58组隧道，是全规模大双孔公路隧道群。

在这种长度的隧道内发生紧急情况是非常危险的，尤其是火灾等。为了减少事故对旅客的伤害，在隧道的两个入口和两个出口处，均安装了道路流量控制系统，这样可以根据紧急事件提供快速响应，控制流量、疏导交通，避免其他驾驶员进入危险区域。

系统需求

工业级设计，可使用隧道内恶劣的现场环境

可将串口PLC接入以太网络

冗余网络，确保系统不间断运行

Moxa解决方案

雪山隧道采用了欧姆龙的PLC，可自动响应信号控制系统，或可进行手动操作。因PLC还带有串口，因此采用了Moxa的NPort 5230串口设备联网服务器，将PLC接入以太网络。当紧急事故发生时，PLC可通过NPort 5230从网络直接获取指令，迅速降低通道流量。

对不同出入口的控制系统而言，数据传输也是十分重要的。系统集成商采用了Moxa EDS-508-SS-SC工业交换机，使用单模光纤组建了一个可靠的工业环网，确保网络的不间断运行。单模光纤环网还通过光纤向上接入本地控制室。基于这样一个可靠的架构，雪山隧道运营方可及时根据不同情况来调整车流量，从而确保驾驶员和车辆的。
