Advanced Phasor Data Concentrator – APDC
APDC is distributed, high performance and scalable application designed for managing modern electrical grids using PMU data.

Real-time data flows in the hundreds of thousands measurement per second—from PMUs and data exchanges between PDCs.
Address both wide area grid management and local applications
Fault-tolerance and monitoring distributed node clusters help ensure high performance.

APDC provides real-time data collection from various sources (PMU, RTU – SCADA, DFR and other IEDs) with high performance (hundreds thousands of measurements per second), scalability and fault-tolerance and distributed nodes cluster capabilities.
