With the continuous development of the global energy Internet,the wide-area interconnection of power grids is supported by technologies such as WDM,and its scale is increasing.The requirements for optical communication networks for wide-area interconnection services are also growing.As the key of service connection control in optical network control plane,which directly affects the service support capability of wide area interconnected optical network.Therefore,in view of the imperfection of multi-service transmission control in various countries under the complex environment of wide-area interconnection,this paper carries out the research of service signaling optimization for power wide-area interconnection optical network.The main work accomplished in this paper is as follows:Firstly,by analyzing the construction of wide area interconnection project and the current situation of communication technology,the long-distance power optical fiber communication technology is chosen to lay the foundation for the subsequent design of power wide area optical network control architecture.Combined with the requirement analysis of wide area interconnection service interaction and wide area scheduling,research on power wide area optical network engineering construction and signaling mechanism is carried out to provide a basis for follow-up research.Secondly,based on the design of the optical network system architecture for energy wide-area interconnection,considering the adaptability environment analysis of transnational submarine optical cables and the selection of optical cables,preliminary design transnational submarine optical network transmission system solution and power wide-area optical network signaling interactive control system.Finally,on the basis of the above research and analysis,the signaling mechanism optimization scheme is designed based on the optical signal-to-noise ratio(OSNR)in optical network physical layer perception.Finally,the OSNR parameters are simulated and verified by using MATLAB.Then,by integrating IEC61970 standard and IEC62325 standard and active security mechanism,the design of transnational power dispatching and transactional information application transmission scheme based on optical network signaling optimization is given,and provides a reference for the future research of wide area power service information transmission scheme.
