The Design And Implementation Of Fuzhou Region Power Consumption Collection Communication Network

At present,with the rapid development of social economy,the construction of smart grid in our country has reached a new stage.As an important part of the smart grid in the power side,the construction of power consumption collection system has entered a crucial stage.With the power consumption collection covering the metropolitan area continues to expand,and smart grid for electricity business data volume further increased and the frequency increasing,the current communication platform of power consumption collection is limited by communication technology,has been unable to meet the demand of smart grid and electricity terminal "data exchange interaction".As a platform for data collection of power consumption transmission,it is urgent to construct a power consumption collection communication network.This article selects the power consumption collection communication network of fuzhou region as the research object.At first,this article divides and classifies the power consumption collection business,calculates the required flow,and establishes different business model.On the basis of quantitative analysis of the power consumption collection business communication demand,a variety of remote communication techniques in the aspect of economy,security,and degree of compatibility carried on the comparison.This article mainly researches the EPON working principle and network model,compares the second and third layer technologies in EPON communication network deployment;At the same time based on fuzhou district power grid and the circumstances(substation location,communication data network convergence layer network structure,etc.),design the power consumption collection communication network convergence layer and access layer of the network topology structure,the light path budget,the protection method,and the equipment deployment(OLT,OUN,ODN).Divide the network resources of fuzhou power consumption collection network vlan and Ip,design the QOS,and in the light of the network security of communication network and the risk of network management strategies are put forward.Finally,the scheme for the engineering practices,proves from practice the theory research and the feasibility of the design of network architecture,provides the regional power companies the reference and experience of the collection of power consumption communication network construction for the future,and lays the foundation of multi-network fusion for the future.
