新建变电站在建设阶段需要与其相邻的变电站建立一个临时通信系统,为了让这种临时通信系统的成本降低,保证系统通信的质量,可采用无线Mesh网络.变电站之间传播路径损耗的研究对Mesh网络的有效性和可靠性具有重要的参考意义.在Okumura-Hata模型的基础上,通过勘测实地的环境参数,增加了校正因子,并用Matlab进行了仿真分析,理论上测得了变电站间Mesh网络链路传播的路径损耗.分析结果表明,传播路径损耗的理论分析,对Mesh网络应用于变电站临时通信系统的组建有重要的意义.

@@@@The new substation in the construction phase needs to build a temporary communication system with adjacent substation. In order to ensure the low cost and the high quality of the temporary communication system, the system adopts Mesh wireless network. It has important reference significance for the effectiveness and reliability of the system to research the propagation path loss between substations. Based on Okumura-Hata model and the measured environment parameters, correction factor is added and Mesh propagation path loss between substations is predicted in Matlab. Results show that, theoretical analysis of propagation path loss applied to temporary communication system between substations is important to the Mesh wireless network.
