摘　　要：地县基层电网的迅速发展对数据通信网提出了更高的带宽需求,针对河南电力地县通信网传输带宽低、结构单一等问题,PTN技术在河南电网的推广应用使地县数据通信网带宽由N*2M提升至10GE/GE。结合河南电力OTN网络建设,河南电力数据通信网形成了完善的三层架构,大大增加了数据通信网的带宽和资源配置的灵活性,为智能电网建设起到了强有力的通信支撑作用。The rapid development of the county grid put forward higher bandwidth demand of data communication network, aiming at problems in Henan county grid communication network,such as low transmission bandwidth and single structure, application of PTN technology makes the bandwidth increase to 10GE/GE from N＊2M for county data communication network. Considering the OTN network construction, data communication network has formed three layer structures in Henan grid, greatly increased the bandwidth of data communication network and the ？exibility of the communication resources allocation, they all played a strong role in communication support for the construction of smart grid.
