海上平台直流输电系统通讯网络优化

Optimization of Communication Network for DC Transmission System of Offshore Platform

文昌14-3A平台直流输电系统自投用以来,其通讯网络出现的问题一直困扰着油田现场,故对其通讯网络硬件以及软件进行升级优化,由原来的以网关为中间通讯链路转换,触摸屏和上位机为通讯主机的方式改造成为RsLogix5000系列PLC为处理的通讯方式,使直流输电系统的可靠性和安全性有了大幅提高。

Since the Wenchang 14-3A platform DC transmission system has been put into use, the problems in its communication network have been plaguing the oilfield site. Therefore, the communication network hardware and software are upgraded and optimized, and the original gateway is used as the intermediate communication link. The way that the touch screen and the host computer are the communication host is transformed into the communication mode of the RsLogix5000 series PLC, which greatly improves the reliability and safety of the DC transmission system.
