Research on Key Technology Innovation of Intelligent Transmission Operation and Maintenance Based on Online Monitoring Technology

With the continuous development of smart grid, the on-line monitoring system of transmission lines has been applied, which has obvious characteristics of networking and informationization, and can mine and share diverse and heterogeneous information, thus helping the line maintenance and intelligent management. In this paper, an anti-interference method combining power and channel adjustment based on geographical location is proposed for the key technical innovation of intelligent transmission operation and maintenance, and nodes are implicitly clustered according to regional characteristics. Each node transmits data with the maximum transmission power and the frequency band corresponding to the area where it is located. At the same time, the design of Hadoop monitoring data model, which conforms to the structural characteristics of smart grid power big data, is proposed, which includes three levels: multi-dimensional data information input, distributed data storage and distributed data processing. The experimental results show that this method can improve the throughput of the network, and reduce the average transmission hop count and transmission delay significantly, thus obtaining better network capacity and real-time.
