配电变电站内部通信网络研究与实践

根据配电变电站自动化系统中通信网络的特点，提出了一种从整体结构上分析评价配电变电站内部通信网络方案性能新方法，冻结合工程实践，用此方法对各可行方案进行了较为详尽的分析比较，在得出优选方案之后，围绕着如何在合理利用通信系统硬件资源的前提下尽可能提高通信系统网络性能的问题，阐述了系统各个通信单元软，硬件的设计思路及方法，最后，在总结实践经验的基础上，提出了一些值得进一步深入 研究的问题。

RESEARCH AND PRACTICE OF INTERNAL COMMUNICATION NETWORKS FOR DISTRIBUTION SUBSTATION

According to the characteristics of communication network for automation system in distribution substation, a new method which analyzes and evaluates the performance of internal communication network project for distribution substation as a whole is given, and combining with engineering practice all the feasible projects are analyzed and compared by the method exhaustively. For the selected project, centering on the question of how to improve the performance of communication network as far as possible under the precondition of rational utilization of its hardware resources, the idea for the design of hardware and software of each communication unit is expounded. Finally, on the basis of practical experience some problems which are worth further studying thoroughly are put forward.
