Online Fiber Optic Monitoring System Of The Power System Of The Snmp-based Monitoring Station-side Software Design And Development

With the economic development of our country, the main way of power system communication has been developed from power line carrier and microwave communication to fiber optical communication and large power system private fiber optical communication network has been constructed. For some reasons, optical fiber, which is the main physical media that carries large amount of important information of power system, may be interrupted inevitably. If we can not maintain and restore it rapidly, it will affect the normal production of power system. So, it is necessary for the power system's safe production and stable operation to develop a supervisory system which could determine the position and cause of the fault accurately and rapidly.Based on maintenance and management of optical cable of the power system optical fiber communication network, the power system optical monitor&manage system is an important platform for the communication and distribution department that ensures the normal communication of power system. Being the key equipment in the supervisory system, monitoring station should be effectively controled and managed. SNMP is selected as the protocol to control and manage monitoring station for its simplicity, little-overhead and strong-extensibility. In this paper, the author carries out an architecture to build a supervisory system based on SNMP.Firstly, this paper introduces the study and development of supervisory system in power system, and explains the principles of the supervisory system. Secondly, this paper describes the development and realization of monitoring station. At last, this paper analysis SNMP and monitoring station, and gives the software architecture, program flow of the SNMP agent in monitoring station.
