“…On one hand, as an emerging communication technology, WSN has the advantages of high monitoring precision, remote telemetry and remote control, self-organization [11], which can be used in the early stages of information acquisition and close range transmission. On the other hand, with the widespread installation of OPGW, combining OPGW separation technology and EPON communication technology [12], data can be transmitted in high speed and reliably by making full use of free OPGW cable cores. This article mainly studies private power communication network that using OPGW in part of towers to make up EPON network and covering other towers by wireless communication.…”

To conquer problems of bandwidth bottleneck and high latency in chain-type wireless communication network for transmission line online monitoring, an optimal model and multi-object-based decision for hybrid hierarchical communication network planning are proposed. A theoretical placement planning model of optical fiber separated towers is formulated with object of cost and end-to-end latency optimization, while satisfying constraints of graph-based path connectivity and bandwidth. Particle swarm optimization algorithm is used to solve the model to acquire the set of Paretooptimal solutions along with the decision matrix. The most satisfactory communication network planning scheme is selected by the multi-attribute decision-making method based on fuzzy entropy weight of Vague set. Finally, the effectiveness of the proposed model and algorithm is validated by results of the case study. Our analysis shows that an optimal placement can be obtained to configure network for delivering information to the dispatching center efficiently and cost-effectively.

“…Although 4G/5G communication can provide enough bandwidth, its operation and deployment costs are higher, and there is no signal coverage in remote mountainous areas [ 6 , 7 ]. Optical fiber composite overhead ground wire (OPGW) of smart grids can provide high-speed and long-distance optical fiber communication, but the network expansion performance is limited [ 8 ]. Considering the above factors and existing technologies, it is a feasible scheme to construct a hybrid hierarchical network compatible with optical fiber communication and a wireless network.…”

With the rapid development of the social economy, high-voltage transmission lines as power supply infrastructure are increasing, subsequently presenting a new challenge to the effective monitoring of transmission lines. The dynamic sensor network integrated with robots can effectively solve the elastic monitoring of transmission lines, but the problems of real-time performance, energy consumption and economy of the network need to be solved. To solve this problem, a dynamic network deployment method based on the hybrid hierarchical network (HHN) is proposed to realize a low-cost, energy-saving and real-time dynamic sensing system for overhead high-voltage transmission lines. Through case analysis and simulation, combined with the vague set multi-attribute decision-making method (MADM) with scheme preference, the network deployment and optimization results under multi-parameter constraints are obtained.

Natural disasters may be of significant impact on overhead transmission lines and cause communication outage related to pilot protection. This paper aims at reconstructing communication channels and maintaining functions of pilot-wire differential protections after the main channel fails. With the development of smart grids as well as new communication technologies, wireless sensor networks (WSNs) have been potential means for realizing reconstructed communication channels (RCCs) without further installation. For a reliable design, system arrangement and the communication structure were presented. Theoretical planning of sensor nodes was formulated, which enjoys advantages such as high reliability, cost optimization, and capacity of satisfying the connectivity of the communication network. To meet the need of time delay, a novel routing protocol for WSNs was proposed with three stages including route establishment, route discovery and route maintenance, which ensured the directional propagation of data packets. Practical experiments and simulation results indicate that the proposed RCC scheme can satisfy time delay of protection relaying in emergency communication channel, as well as guarantee the connectivity of networks when some WSN nodes are damaged.
