A case study based on an optical communication engineering project of the system upgrade for Shanghai Power Telecommunication Network (ShPTnet)

摘要

Optical communication service is becoming a limelight in the field of electricity supply control and management for recent years. On the one hand, most existing power manufacture communication such as control and dispatch systems are migrating from analog to digital formation, which requires stable data communication infrastructure with broadband capacity for ensuring upper layer signal transmission. On the other hand, the latest online business operations of power companies, such as power markets and sales information are exchanged and updated instantly, which also demands a scalable data network architecture as business expands. Thus, this paper presents a case study based on an ongoing engineering project from Shanghai Municipal Electric Power Company (SMEPC). In particular, it is a system upgrade project from legacy SDH network to the latest Multiservice Transport Platform (MSTP), along with the major goal of broadening the capacity for the metropolitan optical communication infrastructure of SMEPC, namely the Shanghai Power Telecommunication Network (ShPTnet).
