IEEE Guide for Centralized Protection and Control (CPC) Systems within a Substation

This guide for Centralized Protection and Control (CPC) systems within a substation addresses the realization of various protection, automation, and control functions within a CPC system utilizing data collected from intelligent electronic devices. This guide includes protection, automation, and control functions within a substation, including interconnecting circuits using devices and their interconnections with suitable communication protocols. This guide includes references to existing standards applicable to protection, automation, and control applications for various types of circuit elements such as generators, transformers, bus bars, shunt and series capacitor banks, reactors, transmission lines, and distribution lines. Some protection and control systems may be applied to protect the integrity of the power system, for example, to avoid cascading outages, equipment damage from unanticipated power system conditions beyond equipment emergency ratings, voltage collapse, angular instability, or other system problems. These systems are referred to as SIPS (system integrity protection schemes). The guide addresses CPC system architectures for typical substation configurations. The guide addresses the reliability and maintainability of each architecture, along with their respective testing requirements. The guide also addresses CPC-based system development, installation, commissioning, troubleshooting, and maintenance.
