The challenge
The more electrified society becomes, the more dependent we become on the power system working properly. And the more complicated the power system becomes, the more vulnerable it is. Small faults that turn into major faults can have serious consequences for society, both practical and financial.
The goal
In EarlyWarn, the goal is to develop a monitoring system, driven by big data and domain knowledge, that detects and identifies errors, preferably several minutes before they occur.
The project
The project uses large amounts of measurement data, which is analysed using machine learning models that in turn develop a predictive algorithm. The theory is that small variations (fault signatures) in the voltage in the grid can predict breakdowns in components and other events that could lead to disruptions and interruptions in the power system. Preliminary trials show good results, although better for some fault categories (total operational interruptions) than for others (earth faults and voltage dips).
