This book is about standardizing the behaviour of Phasor Data Concentrators (PDCs)during data communication. PDCs can collect and process data from thousands of Phasor Measurement Units (PMUs) at rates of up to 60 frames/second. To successfully work at such high data rates, it is important that PMU and PDC communication is seamless. If PDCs are not processing and sending/receiving data correctly then their data cannot be used. It is important to determine what exactly is expected from a PDC under all conditions. For this reason, standards such as IEEE C37.118.2-2011 have been proposed to help...
