Research On Adaptability Of Terminal Communication Access Network Considering Power Multi Service Integrated Bearing

The rapid development of information and communication technology has strongly supported the digital transformation and business innovation of the power industry.Among them,for the power system communication access network,the scale of the wide geographical distributed intelligent devices is large,and application scenarios of intelligent electrical terminals are complicated where the communication technologies are diverse.As a result,all the difficulties lead to repeated construction of terminal communication access networks,and a single communication system cannot meet differentiated communication needs,which has hindered the development of electrical services.Therefore,it is necessary to carry out comprehensive research on the suitability of different types of access network technologies on the distribution power grid,so as to provide a theoretical basis and constructive idea for the rapid,flexible,and efficient networking scheme for the terminal communication access network under the development of new and traditional electrical services.Based on the matching model and facing specific business scenarios,this paper puts forward an optimal adaptability analysis between communication and electrical services based on the analytic hierarchy process(AHP)and fuzzy matching methods.The main researches include:(1)According to the communication technology principle of power access network,this paper analyzes in detail the technical characteristics of various kinds of remote communication and local communication technology,such as design ideas,networking methods,and security protection,and qualitatively points out the adaptability of each technology in different power application scenarios,which lays a theoretical foundation for the research on the adaptability of the power access network.(2)Combined with the characteristics of distribution automation,power consumption information collection,and accurate load control,the multi-dimensional factors such as data type and data flow direction,bandwidth and acquisition interval,transmission distance,real-time performance,reliability,information security are analyzed in depth.Based on the analytic hierarchy process(AHP)and fuzzy matching method,the optimal communication scheme for power services adaptation in the specific scenario is proposed.The mathematical model of technology comparison analysis is constructed to analyze and calculate,by which one can obtain the optimal adaptability of the communication technology bearing electrical services.(3)Besides,this paper also proposes the construction principles of networking scheme for the power communication access network,by the analyzes of characteristics of electrical services communication requirements in the future.This paper mainly considers larger bandwidth,lower delay,higher speed,and lower power consumption as the multi-dimensional targets.Wireless communication technology has the advantages of wide coverage,high bandwidth,flexible deployment,and high economic efficiency compared with other wired communication technology,which is very suitable for remote access of massive intelligent electrical devices(IEDs)widely spreading within wide areas.At the same time,according to the fixed-point geographic characteristic of IEDs,this paper studies the quasi-dynamic resource scheduling algorithm to allocate the optimal frequency and power resources for wireless communication networks bearing different electrical services,so as to achieve the goal of efficient network operation.Through computer simulations,it can be seen that the proposed quasi-dynamic resource scheduling algorithm is superior to the traditional heuristic algorithm,in which its low-complexity and strong-practicability are verified.
