A structured approach to increase situational awareness in low voltage distribution grids
conference paper
Wear and tear, electrification and aging of (low voltage) distribution grids require maintenance in order to assure continuous provision of electricity. Situational awareness is required to find out when parts of the grid need maintenance and which parts should be prioritized. The paper proposes a conceptual value model which relates sensor data from the condition of the asset to the potential value of information (i.e. interpreted data) for the distribution system operators. Distribution density functions account for uncertainties in model parameter values. They can be narrowed down by monitoring relevant degradation mechanisms. To this end, degradation processes are simulated in laboratory scale setups, emulating low voltage cables in moist and submerged environments. Understanding fundamental aspects of degradation, failure and value determination of sensor data allows prioritization of maintenance actions that lead to best results in terms of customers-minutes-lost, remaining useful lifetime of assets and cost-effectiveness. © 2015 IEEE.
