Optimization Algorithm of Power Communication Network Based on the Equivalent Network

Abstract

Electric power communication requires two nodes in the network or cable period expires, the communication network as a whole is still can continue to run. Reliable power network can provide reliable operation of electric power for dispatching communication security. Due to many key network nodes external connectivity in the electric power, communication network has only one path, so once the link damage because of emergencies, these networks because of the failure of nodes (or communication link) and power operation scheduling of exception can occur easily, thus to cause great damage to the safe operation of the whole power network. In order to improve the robustness of system in this case, this paper designed a new optimization algorithm based on the equivalent network to simplify the real network and the network analysis. This paper studies the nature of circular web spider's webs and predator characteristics, analysis of the structure characteristics of the orb web and information transfer mechanism, which constructs the network topology model of single and double artificially cobweb; all terminal reliability of the factor theorem analysis of single-layer artificial spider network topology, analysis results show that, compared with the network topology artificial spider web structure and the traditional star network, ring network, double loop network and star network, with better all terminal reliability and stronger survivability. Index Terms-The Equivalent Network; Power Communication Network; Reliability; Total Quantity of Knowledge I. INTRODUCTION Electric power communication network is to serve the power system communication private network, requires support for power system protection and required for high speed and real-time communication, therefore, the safety and reliability of the electric power communication network for communication, protection and control the rapidity and accuracy of the information transmission has very strict requirements [1]. To ensure safety, reliability and efficiency of electric power communication system and improve the communication system of affordable, according to the requirements of the network structure, operation mode, and consider the communication protection of accident caused by negligence and atrocious weather system, in the network the return of any two components damage does not affect the normal operation of the entire network, important business is not broken [2]. Based on this consideration, the design meets the requirements of network optimization algorithm, and put forward the scientific and reasonable network construction plan become the key problem [3]. Smart grid including power generation, transmission, and distribution and electricity sectors such as the communication network, carrying the communication business links advanced distribution operation, advanced measurement system, advanced transmission operation and advanced asset management etc [4]. Smart grid communication according to the function can be divided into enterprise management and operati...
