摘　　要：针对智能电力通信网络存在的数据不兼容的问题,提出了一种基于DLT_645的Modbus/TCP通信协议.通过分析电力通信网的功率计算方法,讨论智能电网的交互需求,并按照需求分析结果制定智能电表与采集终端之间的数据传输策略,同时给出了该协议网络接口的硬件设计.仿真测试结果表明,与常用的Modbus/RTU协议相比,该改进的Modbus/TCP协议具有更低的平均响应时间、更快的执行速度和较高的数据传输成功率.Aiming at the data in compatibility problem of intelligent power communication network,a Modbus/TCP communication protocol based on DLT_645 was proposed.By analyzing the power calculation method of power communication network,the interactive demand of smart grids was discussed.According to the demand analysis results,the data transmission strategy between the intelligent meter and the acquisition terminal was formulated,and the hardware design of network interface protocol was provided.The simulation results show that the improved Modbus/TCP protocol has lower average response time,faster execution speed and higher data transmission success rate,compared with the conventional Modbus/RTU protocol.
