Centralized Protection and Control (CPC): Next Level Of Electrical Protection System Towards Digital Substation (Oil and Gas)

This paper is prepared in line with IEEE publication requirements which describes the Centralized Protection and Control (CPC) as the new level of electrical protection system towards supporting digital substation. This paper is prepared with the intent to share about current industry challenges, the values brought by CPC, current efforts in realizing CPC, the requirements, aspiration, as well as the risk associated to CPC installation in oil & gas industry. Centralized Protection and Control or CPC is a protection system with the concept of relocating the functions and features that resides in a protection relay to a centralized device. As protection system is one of Safety Critical Element in Oil and Gas Industry. Operation and Maintenance (O&M) team is looking for features to operate and manage protection relay in a more advanced manner. As the technology evolved, the advancement of hardware capability allows for more computing power in a centralized device to process larger protection data and execute protection function. By having a centralized protection device, complete with digital database supported with analytical tools, and customized features, managing a wide range of protection relays in large scale electrical installation becomes easier and more efficient. Digitalization, centralization, remote monitoring and remote automation are the key step towards realizing digital twins of electrical protection system, thus supporting the reduction of operational costs in such facilities.
