The power sector is challenged to keep the electricity network reliable and affordable. With an increasing number of renewables and smart electronics added to the electricity network, the power grid must cope with more dynamic stress each year. To prevent outages from happening, it is essential that grid operators are able to locate and respond to faults in the grid quickly and can repair weak spots before the grid fails. DNV GL has launched its upgraded Smart Cable Guard 2.0, which is a data-driven online monitoring solution, that assists system operators to prevent power outages by locating weak spots and faults in cables within minutes to an accuracy of 1% of the cable circuit length.
Jacob Ruiter, regional director Benelux at DNV GL, explains: "The power industry is entering a new age. How we generate and use energy is changing, so power systems must evolve to match. The potential for digital technologies and smarter use of data in our industries is enormous, enabling greater connectivity and controllability. With Smart Cable Guard 2.0 we enable system operators to digitalize its operations and to keep grids safe and reliable, resulting up to 25% fewer failures compared to traditional methods. This, in turn, leads to cost savings, and when applicable, lesser penalties by the regulator."
"Smart Cable Guard 2.0 includes a state-of-the-art fault locator and online monitoring function that considerably reduces the average outage frequency and duration figures. The system operator is proactively informed via a web interface about the locations of potential cable weaknesses, using state-of-the-art algorithms to analyse data collected from sensors. This saves time and money normally spent locating the problem and helps to make repairs quickly. This unique technology works in any type of network and makes it possible to detect full and intermittent faults which have not been detected before.", says Dr. Fred Steennis, Power Cable Expert at DNV GL.
DNV GL's Smart Cable Guard technology has been rolled out in many networks around the world. In the Netherlands, DNV GL has teamed up with Dutch distribution system operators (DSO's) to help them manage and monitor the distribution grid, analysing sensor data to allow the DSO's to prevent and resolve problems fast.
