Abstract
This article discusses the recent trends and customer experience with the deployment of centralized protection and control (CPC) systems mainly by utility segment customers and its feasibility in the chemical, oil, and gas (COG) segment. (See “Abbreviations Used in This Article” for a list of abbreviations used throughout.) CPC represents a new approach to protection and control in power distribution networks—centralizing all protection and control functionality in one single device on the substation level. Being International Electrotechnical Commission (IEC) 61850-compliant and ready for future upgrades with the evolving grid, it supports optimal asset management. To demonstrate the improved utilization of technologies for CPC systems, this article describes (i) a new centralized/hybrid protection and control (HPC) scheme for the medium-voltage/low-voltage (MV/LV) network, (ii) benefits to substantially improve the “ease of operation and maintenance” of industrial plants, and (iii) supplier and end customer perspective with the pros and cons of this new CPC system and its feasibility for deployment in COG industries.
