Islanding Detection in Distributed Generation

Pujhari, Truptimayee (2009) Islanding Detection in Distributed Generation. MTech thesis.



In this work, a case-study of distributed Generation System comprising of two 9 MW wind farms (each connected to a120 kv grid through a 20 km,25kv feeder),two 500 kW resistive loads and two .9MVAR filters, have been considered and studies are made on islanding detection using those above mentioned methods. The proposed techniques are tested on islanding and possible non-islanding conditions such as normal operation, sudden load change and tripping of other DG etc. and found to be highly effective in islanding detection at different target DG locations in the power distribution network including multiple DGs.
