Synchrophasor based Islanding Detection method
PRZEGLĄD ELEKTROTECHNICZNY, 2015 Unintentional islanding is one of the most disturbing issues of distributed generation. It has serious consequences for electricity and it poses a threat to life and health of the personnel. This paper makes a comparison between two islanding detection methods.

A Software-based Low-Jitter Servo Clock for Inexpensive Phasor Measurement Units
, 2018 This paper presents the design and the implementation of a servo-clock (SC) for low-cost Phasor Measurement Units (PMUs). The SC relies on a classic Proportional Integral (PI) controller, which has been properly tuned to minimize the synchronization ...
