Distributed generation (DG) units are widely used in
modern power grids. The sub-grid islanding condition associated
with a loss of mains (LoM) in such grids is a topical safety
issue. In this paper, we discuss potential anti-islanding solutions,
analyze the physical constraints, propose a power line communication
(PLC) based concept, and perform its sensitivity analysis.
The concept description covers a system topology, a signalling
mechanism, communication hardware, and a direct sequence
spread spectrum (DSSS) based software signalling algorithm. The
designed concept is evaluated in the laboratory environment using
software-defined radios (SDR), a medium/low-voltage (MV/LV)
distribution transformer, and a white noise generator. Test results
and their analysis are presented. The signal-to-noise ratio (SNR),
the carrier frequency, the spreading code (SC) length, and
the synchronization key (SK) length are analyzed as sensitivity
factors, and operational results of the concept are discussed.
