Essential for Smart Grid: Distributed Temperature Sensing for Real Time Power Cable and Overhead Line Monitoring

Essential for Smart Grid: Distributed Temperature Sensing for Real Time Power Cable and Overhead Line Monitoring

Load Management – Optimization and Save Grid Operation

As demand for electricity continues to grow, so do the challenges to power companies and power grids. The liberalisation of power supply markets continues apace, resulting in the reorganisation of national and international networks. Events of the past few years – including large-scale blackouts and shortfalls in major markets, and the ongoing addition of alternative sources to existing networks – point up the need for improvements to existing infrastructures. At the same time, there is increased pressure to keep costs to a minimum.

Temperature monitoring is a key factor for the optimisation of underground power transmission and distribution installations. The conductor temperature depends on the load, but other factors such as the thermal soil resistivity, the power line arrangement, adjacent cables and other sources dissipating heat into the surrounding area have an important impact on the performance of the installation. Up to now, it has been almost impossible to foresee the temperature distribution along the cable route, so that the maximum applicable current load was usually set as a compromise between understanding of operation conditions and risk minimisation.

Access the Thermal Conditions of the Power Cable in Real Time

The availability of industrial Distributed Temperature Sensing (DTS) systems that measure in real time temperatures all along the cable is a first step in monitoring the transmission or distribution system capacity. The integrated Dynamic Cable Rating (DCR) or also called Real Time Thermal Rating (RTTR) solution offered by LIOS enables not only to conti-nuously monitor the temperature of a high voltage cable circuit in real time, but to safely utilize the existing network capacity to its maximum. Furthermore it provides the ability to the operator to predict the behaviour of the transmission system upon major changes made to its initial operating conditions.
