One of the important trends in design of new overhead lines over the past 20 years has been development of structures and designs that are less obtrusive and more pleasing visually. Much the same process has also been going on at substations. For example, even 25 years ago, efforts had already been in place as far afield as Finland and Australia to build substations designed to facilitate acceptance by affected communities – either through aesthetic...
Reducing engineering costs using IEC 61850 BY ADAM GAUCI, Schneider Electric As substation automation is moving towards software environments based on the International Electrotechnical Commission’s substation automation standard, IEC 61850: “Power Utility Automation”, the engineering process...
Exploring 3-D design techniques for electrical substations BY MIKE MINELLI, & HAROLD HARKONEN, Nordmin Engineering Since the 1970s, engineering consulting firms typically have been designing substations using two-dimensional computer aided design software (CAD). This common technique produces...
How to protect electrical equipment from Mother Nature BY ROBERT A. MURPHY, Trayer Engineering Corporation The U.S. National Weather Service called Hurricane Sandy the most destructive storm of 2012’s unusually active Atlantic hurricane season. Sandy delivered unprecedented damage across a wide...
How new technologies can improve monitoring and control BY LOURENCO TEODORO, InduSoft Substations are a critical component for maintaining electrical supply and load control in low voltage, medium voltage and high voltage electrical distribution networks. In order to ensure the proper functioning...
From Hardwiring to Data Networking The modernization of substations is as much a communications revolution as a protection one. For decades, copper conductors carried analog signals from instrument transformers to relays and controls. Each new circuit meant more wiring, more panels, and more room...
Reliable and secure communication infrastructure is essential to the safe and efficient operation of the modern power grid. As utilities transition to digital substations, integrate distributed energy resources (DERs), and deploy real-time monitoring systems, the need for robust, scalable grid...
The power industry is undergoing a profound transformation driven by grid modernization, renewable integration, and increasing demands for resilience and efficiency. At the heart of this evolution lies the smart substation—a next-generation facility equipped with advanced sensors, digital...
The IEC 61850 protocol has become the global standard for substation automation, enabling high-speed communication, interoperability, and streamlined integration of intelligent electronic devices (IEDs). It plays a foundational role in transforming traditional substations into digital substations...
A coalition of large energy consumers and ratepayer advocates has filed a complaint with the Federal Energy Regulatory Commission (FERC), urging the agency to prohibit transmission owners from independently planning "local" transmission projects exceeding 100 kilovolts (kV). The coalition argues...
In the rapidly evolving landscape of power grid management, digital twin technology is emerging as a game-changer for substations. By creating virtual replicas of physical assets, digital twins bridge the gap between the physical and digital worlds, enabling enhanced operational efficiency and...
