| 摘 要： | 以彭城发电厂MAX1000分散控制系统网络结构为例，介绍其存在的问题以及技术改进情况。通过采用以太网星形结构的网络连接方式，将分散控制系统由总线形网络拓朴结构改为星形网络拓扑结构。实践表明，改进后彭城发电厂MAX1000分散控制系统网络的安全性得到了提高，MIS系统网络的可靠性也得以改善。

| Abstract: | Taking the network structure of MAX1000 distributed control system in Pencheng Power Plant as example, the existing problems and technical retrofit of the said system have been presented. Through using network connecting mode of ether star structure, the distribubuted control system has been changed from busbar network topologic structure into a star network topologic structure. The practice shows that the safety of the network for MAX1000 distributed control system in Pencheng Power Plant have been enhanced, the reliability of MIS system has also been perfected. |
