Design of passive network data transmission protocol for power transmission and transformation detection

针对无源网络在电力系统输变电检测领域的应用问题,提出了一种面向输变电检测的无源网络数据传输协议设计方案。该方案分析了基于无源通信网络的输变电检测系统架构,包括设备层、感知层、数据层与应用层,并针对传统无源网络通信效率低、能耗高及质量较差的缺点,提出了一种改进的批量数据传输协议。其通过“消息”通信模块节约每个通信回合中的能量与内存开销,采用突发传输模式使无源节点能够响应通信回合中的所有时隙,进而拓展突发通信标识以解决多无源节点系统中通信碰撞的问题。以某电网为例进行的仿真测试结果表明,文中所提方法相比于传统数据传输协议,具有较高的系统能效与服务质量,能够提高电力系统输变电检测业务的智能化水平。

In view of the application of passive network in the field of power transmission and transformation detection,a design scheme of passive network data transmission protocol for power transmission and transformation detection is proposed in this paper.The architecture of power transmission and transformation detection system based on passive communication network is analyzed,including equipment layer,perception layer,data layer and application layer.Aiming at the disadvantages of low communication efficiency,high energy consumption and poor quality of traditional passive network,an improved batch data transmission protocol is proposed.Through the“message”communication module,the energy and memory overhead in each communication round are saved.The burst transmission mode is adopted to enable the passive node to respond to all time slots in the communication round,expand the burst communication identification,and solve the problem of communication collision in multi passive node system.The simulation test results of a power grid show that compared with the traditional data transmission protocol,the proposed method has higher system energy efficiency and service quality,and can improve the intelligent level of power transmission and transformation detection business of power system.
