在阐述低压配电网电力线载波通信网络拓扑和特征的基础上,结合PRIME标准中媒体访问控制(MAC)层的帧结构、类型,深入归纳、分析和总结了PRIME标准中的电力线载波通信组网初始化算法、网络维护与重构算法。通过采用电力线载波芯片ST7590T,应用PRIME标准协议,在某一厂区搭建96节点的现场测试环境,实例分析该组网方案的初始化和网络重构过程,并针对现场可能出现的状况,验证了该组网方案的灵活性、抗毁性和现场可应用性。
Based on the topology and characteristics of power line carrier communication network in low voltage distribution network and the frame structure and type of media access control (MAC) layer in PRIME standard, this paper analyzes and summarizes the power line carrier communication network Initialization algorithm, network maintenance and reconstruction algorithm. By adopting the power line carrier chip ST7590T and using the PRIME standard protocol, a 96-node field test environment is set up in a factory. The example analyzes the initialization and network reconfiguration of the network plan and verifies the possible situation of the site. Network program flexibility, invulnerability and on-site applicability.
