摘要

Distributed generation (DG) units are rapidly increasing and most of them are interconnected with distribution network to supply power into the network as well as local loads. Islanding operations of DG usually occur when power supply from the main utility is interrupted due to several reasons. Islanding conditions cause negative impacts on protection, operation, and management of distribution systems; therefore, it is necessary to effectively detect the islanding conditions and swiftly disconnect DG from distribution network. This paper focuses the attemption on two active methods for islanding detection. In particular, simulation models have been implemented and some experimental results have been obtained using ATP - EMTP simulation program.
