Fault Detection And Location In Low Voltage Grids Based On Distributed Monitoring

The paper presents results from the Monitor BT project - an R&D project supported by European funds and granted by the Portuguese Strategic Reference Framework. The project has two main objectives - first to develop and deploy new functionalities for fault detection and location in the Low Voltage (LV) grid, based on the data provided by distributed sensors; and second to dynamically control of the injected power by photovoltaic micro-generators for voltage control. This paper presents results regarding the first objective where local sensors collect data from the LV grid and this information is processed locally to detect the faulted branch.
