Understanding Cyber Security Standards

Electric power system protection, automation and control devices perform many functions over different communications interfaces. This requires careful consideration by industry experts in order to ensure that all developed standards and recommendations can be successfully implemented without causing a decrease in the performance of any of the system components or functions. These are some of the ... More

Wide Area Coordination Study of Protection Coordination in the Transmission System and Boundaries

Detecting a lack of coordination before relay misoperations occur reduces risk of interruptions in service, brownouts, and blackouts. Automated Wide Area Coordination reviews are a practical way to increase system reliability.In 2006, Rede Eléctrica de España (in Madrid) conducted a wide area review of protection coordination in a large portion of their transmission network, including the boundari... More

Impact of Sun Storms on GPS based devices

The impact of sun storms on electric power grids has been subject to many papers, articles and reports during the last two decades.System disturbances caused by solar activity can disrupt complex power grids due to the geomagnetically induced currents (GIC) resulting from the interaction of the Earth's magnetic field and ionized particles carried by the solar wind. Severe magnetic storms induce el... More

Microsoft "Surface" Puts People in Control

Imagine being able to place a relay on your desk, and the desk suddenly comes alive, pops-up the settings of the distance zones, shows the loading of the transmission line it is installed on and the apparent impedance seen by the relay, while at the same time your colleague is looking at the COMTRADE file from the latest relay operation.This and much more will be soon possible with the recently an... More

Wireless Power Transfer - it is Real!

I believe everybody was happy when we were able to get rid of all the phone and Ethernet cable and connect to the Internet using WiFi. But we still need to plug in all our electronic devices to charge their batteries. And with all of them having different adaptors, connectors, voltage levels, etc., they create a big mess around us. The dream for wireless power transfer is not something new. A team... More
