基于自适应和可靠机制的电力宽带网络通信

Electric power broadband network communication based on adaptive and reliable mechanisms

针对目前电力自动化系统已建成的宽带通信网络存在的带宽未能有效利用以及采用UDP协议传输数据时存在的不可靠问题,提出了一种自适应机制和一系列可靠机制。其中自适应机制应用一个计算模型,以发送合适的数据通信量自动适应当前网络的状况,使当前网络带宽得到充分利用;可靠机制包括类似于TCP协议的重传、流量控制策略以及缩减通信量策略,使UDP传输具备可靠性.实验结果表明自适应机制和可靠机制可以改善电力自动化系统宽带网络通信的带宽利用率及数据传输的可靠性。

In accordance with the low usage efficiency of the broadband network bandwidth and unreliability of the UDP protocol in electric power automatic system, an adaptive mechanism and series of reliable mechanisms are presented. The adaptive mechanism is to search an appropriate payload with a computing model. The bandwidth can be fully used in every situation of network. The reliable mechanisms are designed with TCP-like retransmission, flow control and decreasing traffic strategies. The result of experiment shows that adaptive mechanism and reliable mechanisms are effective.
