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

This paper explains scalability as it relates to process bus solutions, and identifies the need for scalability for such systems, in particular for the HardFiber system.

This paper looks at the needs of next generation communication systems and provides an overview of the IEC 61850 protocol and how it meets these needs.

This paper describes basic digital radio technology and shows possible applications for distribution protection. As with other pieces of the protection system, it is important to understand the reliability and performance of digital radio.

This paper outlines the high-level design principles for protection and control systems, illustrated using a practical solution for implementing ultra-critical protection and control IEC 61850 process bus applications.

This paper describes some of the critical engineering, design, and applications of the latest technology for the implementation of System Integrity Protection Schemes (SIPS).

A huge opportunity for material, time and manpower savings exists in the reduction of substation copper control cables. Read about American Electric Power’s journey to removing control cabling and replacing it with fiber-optic communication.

To make the smart grid a reality, utilities need to leverage intelligence for smarter, faster decision making. So how do you collect, organize, distribute, integrate, secure and interpret the vast sea of information in today’s grid environment?

This paper presents a new Distributed Bus Protection System that is not only as a protection system, but also a platform that incorporates the data from the HV equipment in an IEC 61850 process bus scheme.

This application note shows that when the time constants are properly matched, the relay works correctly on cyclic loads. It also provides practical examples of how to set up the Multilin 469 relay.
