Editorial
If we ask many people about their opinion regarding digital substations and what they are doing about it, we are going to get many different answers. The differences depend on multiple factors, such as: What do they understand a digital substation to be? How comfortable they are with trying something new? How well do they understand the benefits of digital substations in comparison with... More

However, with the digitalization of the electric power grid communications become a key component of PAC systems, so even that we already have a Communications & Cyber Security Committee w... More

OMICRON electronics

CT Analyzer: current transformer testing better than ever OMICRON’s CT Analyzer was the first device to facilitate effective on-site tests on current transformers (CTs). It is still the only device to allow comprehensive CT tests with accurate results operating at safe 120 V. In addition, it weighs only 17lbs (8 kg). Once again reworked, it now features higher sensitivity, a ... More

IEC 61850 Update

Quality Bits - Clarifications with Edition 2.1

Based on some recent discussions, I realized that apparently, there is still some confusion related to some basic concepts of IEC 61850. Those should be clarified with Edition 2.1 of the core parts of IEC 61850. First, it should be noted that there were some reallocations of specifications between IEC 61850-7-2 and -7-3. With the rearrangement, all types of the definitions are now in part ... More

Lessons Learned

Experience from Statnett R&D Digital Substation Project

Traditional philosophy for transmission systems where protection and control functions are divided in separate hardware units was challenged by a more compact hardware design. The Digital Substation pilot includes protection and control functions for two 300 kV transmission lines in the same IED hardware (hereafter named Protection and Control Unit - PCU). The objective of this compa... More

First Digital Substation ? A journey, business case, lessons

IEC 61850 has now been accepted 'almost unequivocally' as the preferred standard for substation communications. Utilities and industries across the world are at various stages of adoption of this standard. The extent of utilization of this standard in the majority of installations around the world is at ‘station bus’ level with IEC 61850-8-1 reporting and GOOSE. Moving further al... More

"Postes Intelligents" Design, Test and Commissioning of Rte's first completely Digital Substation

Rte's “Postes Intelligents” project (Smart substation in French) consists of the refurbishment of two substations (Blocaux 225 kV / 90 kV and Alleux 90 kV, see page 46) and the upgrading of other substations, located in the same area in northern France. This area features a large amount of wind generation prone to occasional transmission line congestions. It is worth exploring w... More

Bullying - No longer just limited to the classroom, it may even land you in court!

Bullying is generally defined as unwanted, aggressive behavior which involves a real, or perceived power imbalance. Traditionally, and most commonly, bullying is associated with such interaction among school aged children. Typically, such behavior manifests itself when the perpetrator abuses his or her power, which may be in the form of physical strength, access to embarrassing information or... More
