This paper discusses hybrid substation automation solutions, concentrating on the inclusion of alternate technologies. Evolutionary scenarios are used to highlight the conversion from alternate technologies to IEC 61850.

This paper reviews cyber-security requirements for a process bus-based protection and control system, using NERC CIP as a reference. General attributes and functional requirements for a process bus network are described.

This paper highlights trends and expectations of the electric power industry for the next generation protection, control and automation systems. Copper-based signaling and a simple, robust architecture are key elements.

This paper presents a new process bus system for protection and control using IEC 61850 process bus as a technical framework.

This case study shows how a strong and determined team of relay manufacturers and TVA engineers made this Bradley project a success in utilizing the IEC 61850 standard as much as practically possible.
