Abstract:
The island is an unregulated power system. Its behavior is unpredictable due to the power
mismatch between the load and generation and lack of voltage and frequency control. For the
micro grids to be operated safely and consistently, it is necessary to detect the islanding
condition in a grid in a very quick and accurate manner.
This thesis report provides a concise view of the development of a power system network
using Real Time Digital Simulator (RTDS) and then different passive islanding detection
techniques are discussed. A new islanding detection method based on the cumulative sum of
the superimposed power is also proposed in the thesis which works satisfactorily in different
islanding and non-islanding conditions.
