The Institute of Electrical and Electronics Engineers (IEEE) approved a standard on naming time sequence data (TSD) files during events at substations.
It also began work on a new substation standard for cyber-security devices and the revision of its guide for temporary protective grounding systems in substations.
The IEEE approved IEEE C37.232 - Recommended Practice for Naming Time Sequence Data Files, a new substation standard that provides for naming TSD files, event sequences and periodic logs.
It was written to resolve problems associated with reporting, saving, exchanging, archiving and retrieving large numbers of files.
The practice in this standard was adopted by utilities and manufacturers and is recommended by the National Energy Regulatory Commission (NERC) and the Northeast Power Coordinating Council.
The new standards project is for IEEE P1711 - Trial Use Standard for a Cryptographic Protocol for Cyber Security of Substation Serial Links, which will help utilities create procurement specifications for interoperable, open-system, cyber-security devices that protect asynchronous serial communications against cyber attack.
At this time, serial supervisory control data acquisition systems (SCADA) and engineering access ports are not secure, said the IEEE. IEEE P1711 will incorporate the American Gas Association cryptographic protocol, written to implement requirements in IEEE 1689 and improvements in this protocol suggested by Sandia National Laboratories, as well as lessons learned from utility field testing.

The IEE also began to revise IEEE P1246 - Guide for Temporary Protective Grounding Systems Used in Substations to expand the use of multiple temporary protective grounding (TPG) systems and add material on inductive reactance and current heating effects. This guide covers the design, performance, use, testing and installation of TPG systems and suggests good practices, technical information and safety criteria as an aid in selecting and applying these systems.
