High Resolution Sensors Open New Windows onto the Grid
The advances in transmission and distribution (T&D) system sensors, communications, and visualization technology are remarkable. At DistribuTECH 2015, I was able to talk to key vendors in the T&D marketplace, including established players, such as ABB, GE, Landis & Gyr, Schweitzer Engineering Laboratories (SEL), and Siemens, as well as emerging companies, such as Genscape on the transmission grid and Tollgrade on the distribution grid, which both offer innovative new monitoring and visualization solutions. These relatively young companies are taking the industry to a next level in sensor technology, wireless communications, and visualization/analytic tools.
While Genscape is a new entrant in the transmission operator/utility marketplace, it operates the world’s largest private network of in-the-field monitors, providing cloud based software as a service (SaaS) applications for market intelligence across the power, oil, natural gas, petrochemical, agriculture, biofuels, and maritime freight sectors. The company’s applications are used by most energy trading companies, and are used to non-intrusively monitor generation plant outputs, outages, and other transmission line conditions.
Genscape has a wide range of customers in electric power trading and oil & gas commodity markets. With the recent acquisition of Promethean Devices in 2014, Genscape also provides high resolution, sub-second transmission line monitoring of current, conductor sag/clearance, conductor temperature, and voltage, using an easy to deploy ground based solar powered sensor system. With the high cost of land-based fiber systems typically installed by utilities, Genscape’s solution offers an elegant and relatively inexpensive cloud-based solution.
Focused primarily on the medium-voltage (MV) and low-voltage (LV) distribution grid, Tollgrade offers bolt-on line sensing units with high speed wireless communications capabilities, as well as a cloud-based SaaS optimization and visualization tool set that can be tied into a utility’s distribution automation system. The company’s fault-detection hardware and predictive analytics software are designed to assist distribution network operators in avoiding network outages and reducing customer downtime. The sensing units are low cost and can be installed by a distribution system lineman in minutes at any location on the distribution system.
The really striking thing about Tollgrade’s technology is the analytics and visualization tools, which can be used to drill down in outage and fault data to screen, locate, and then analyze breaker trips and outages anywhere on the monitored portions of the distribution network in real time.
Both of these companies have the potential to significantly change the level of visibility into T&D grid performance, providing tools for understanding the disturbances that are never seen in the data typically collected by utilities using conventional solutions.
