As the substation RTU takes on more applications, such as Human-Machine-Interface (HMI), alarm annunciation, math & logic and “relay communication processing”, its need for high availability increases. Anything that takes the RTU out of service – configuration change, firmware update, or component failure – means not only loss of SCADA but also loss of local visibility, loss of non-operational data and, in some applications, loss of local control. Redundancy can address the needs for higher...
How Smart Grid technologies can transform the power industry BY DANIEL PÉLOQUIN, Schneider Electric Energy customers—both consumers and businesses—depend on reliable, affordable power. In North America, consumers take this privilege for granted. However, both the reliable and affordable...
Asset and risk management for electric utilities BY SIRI VARADAN, UISOL, & SERGE VANASSE, Clevest Aging transmission and distribution (T&D) infrastructure is a critical issue for electric utilities, resulting in the need for utilities to make decisions regarding the replacement, repair, or...
Recent technological and economic events are poised to transform the electric utility industry. Described as “game changers” by industry thought-leaders, these “disruptive challenges” stem from a convergence of factors. 1 Distributed energy resources (DER) and demand-side management (DSM)...
Exploring communications for real-time network visibility BY DONALD POLLOCK, Ambient Corporation In August 2013, a report entitled “Economic Benefits of Increasing Electric Grid Resilience to Weather Outages” prepared by the White House Council of Economic Advisors and the U.S. Department of...
Distributed energy resources (DERs) can benefit the power system and individual homes and businesses. DERs can increase the resiliency and reliability of the power grid, reduce greenhouse gas emissions, reduce the overall power cost, and provide power at the point of use. Several types of DERs can...
Brief Background: In the early 1900’s Aluminum Conductor Steel Reinforced (ACSR) conductor was developed to replace copper wires, due to the war effort when copper was needed for munitions. In the 1970’s growing demand for electricity inspired the development of higher capacity...
This project won EEI Transmission Project of the Year – 2016 Description: 240 circuit miles, 345 kV line, double bundleProject: Replace 1,440 miles of ACSR conductor with ACCC Objectives Improve reliability (reduced sag and corrosion) Increased capacity to serve growth (2X...
A recently published report by the US Government Accountability Office (GAO) highlights the significant cybersecurity risks facing the nation’s power grid. One of the key findings in this report is that “the grid is becoming more vulnerable to cyberattacks - particularly those involving...
If you thought growth in renewable electricity generation was a big deal – and it is – you haven’t seen anything yet. Full-scale transformation to a cleaner, smarter and more flexible grid will be driven by a suite of innovations – referred to as Distributed Energy Resources – that...
The idea of a cyberattack on the power grid may invoke images of flickering lights and a race against the clock to block an intrusion – but, often the most serious threats aren’t that obvious or dramatic.Cyber threats that target critical infrastructure facilities like the power grid...
