Distributed generation is increasingly likely to play a major role in electricity supply systems as recognition is made of its low carbon credentials. However, the integration of these units at distribution voltages is a major challenge for utilities. One particular issue is that generators may, unintentionally, continue to supply local demand when areas of the network are isolated from the main system...
This paper presents a transient probabilistic-based technique for earth-fault detection in isolated and compensated neutral medium voltage networks. In these networks, the magnitudes of the fault currents are very small and the straight comparison of magnitudes may lead to risk of malfunction, especially at high fault resistance. The proposed technique is based on Bayesian theorem for selecting the...
