多种新能源接入通信网的差异化QoS研究

Research on Differentiated QoS of Access Communication Network for New Energy Sources

由于新能源接入网以不同的通信协议为基础,不同协议中各类报文传输的可靠性和时延需求在电网中需要得到保证,因此文章对电网差异化QoS原理进行研究。文章主要研究数据流分类及标记技术、数据流量管理及整形技术、拥塞管理和规避机制以及几种经典队列调度算法的比较,给出了标记技术映射导则、令牌桶原理的应用和拥塞解决方法,详细介绍了QoS实现的关键步骤和主要技术,为实现电网差异化QoS提供原理支持。

Scince different communication protocols are adopted for different new energy sources, it＇s hard to guarantee the reliability and time delay of transmission of messages in power grid. Therefore, this paper focuses on differentiated OoS in the power grid, the data stream classification and labeling techniques, traffic management and traffic shaping technique, and congestion management and avoidance methods are studied, as well as numerical queue scheduling algorithms are compared. Furthermore, the mapping among labeling techniques, the principle of token bucket, and solutions to congestion are provided. The key steps and main technologies of QoS implementation are introduced in detail, which provides the principle support for realizing the differential QoS in the power grid.
