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.

Capabilities

  • Real time & historical PMU data via an integrated database management system
  • Fast search in historical archive (roll-up technology)
  • Unlimited synchronous data streams from multiple sources
  • On-line oscillations monitoring (magnitude, frequency, damping)
  • Finding oscillations groups
  • Monitoring of generators’ excitation system faults
  • On-line thresholds violations, disturbances & emergency conditions -determinations and alarming
  • On-line data calculations
  • Real time and “on demand” data redistributions

Connect

APDC receives data from virtually any source and exchange adaptor —PMUs, IEDs etc. It effectively collects and conditions all acquired data from equipment models, storage, grid models, and measurement models. High Performance distributed Historian provides unmatched PMU data ingestion, search and scalability

Blackout Prevention System

Our Blackout Prevention System (BPS) has successfully been integratedand used across electrical plants. The major capability of this system is the prevention of blackouts and to minimize or eliminate the damage they cause. It supports monitoring and predicting the conditions of a power system in real-time.

Acquire

The cloud-based data collection system ensures all data coming from the power system is collected in real-time. The PowerLink BPS solution is built on scalable architecture which ensures millions of data can be collected in real-time without interruptions.

Monitor

The low-frequency oscillation (LFO) monitoring and source determining subsystem is based on synchronized phasor measurements. In-app synchronized measurement applications are used to detect heavy, amplified oscillations—which are harmful to stability in power systems—and the components responsible for them. It also handles LFO power and energy calculations with a view to raising an alarm according to severity assessments.
