Computer Network System in Thermal Power Plants and Its Application

湛江发电厂因形势需要，进行了网络系统的升级。网络系统采用星形拓扑结构：系统由中心交换机、二级交换机、远程服务器、网络服务器、调制解调器和路由器组成；具有支持虚拟网和具备第３层交换能力。该厂利用该网络系统实现办公自动化，作为生产的工具和实时监测系统，随时采集生产现场的数据，在电力局的信息系统内共享，可及时了解发电厂的生产运行情况。

ZHanjiang Power Plant has upgraded the network system of the plant due to situation demand.The net system uses the star - shape topologic structure. The system consists of a central exchanger, secondary level exchanger, remote server, net server, MODEM and rout- ing device, which is capable to assist virtual net and exchange at the third level.With this net system the plant has realized administrative au- tomation.As a production tool and real time monitor system,it collects the data from the production site at amy time,shared within the infor- mation system of the power bureau to understand production and operation of the plant proptly.
