VCL-PDC, Phasor Data Concentrator

Get Data Sheet

VCL-PDC (Phasor Data Concentrator) is a high-performance platform for managing Synchrophasor data and processing streaming data in real-time. The VCL-PDC receives and time-synchronizes phasor data from multiple Phasor Measurement Units (PMUs) to produce real-time, time-stamped output data stream. A PDC can simultaneously store and send PMU data to multiple locations. By using multiple PDCs, customer can create multiple layers of concentration, within a Synchrophasor data system. Various utilities are included to streamline the initial setup, configuration and testing process. The VCL-PDC is a very versatile and easy-to-use phasor data concentrator.

Features and Highlights:

  • Ruggedized, IEEE 61850-3 Compliant Hardware
  • Fanless, High Reliability System
  • Quad Core Pentium Processor with 8GB RAM
  • 2 x Gigabit Ethernet Interfaces
  • 1 x Gigabit Optical Ethernet Interface
  • 1 x IRIG-B Input Port
  • 1TB SSD (1024 GB) Internal Hard Disk for OS and Data Storage
  • Data Storage Capacity of PMU data at 50 (M Class) Frames / Sec - 2,646 days / 7.25 years
  • Data Storage Capacity of PMU data at 25 (M Class) Frames / Sec – 5,291 days / 14.49 years
  • 1 x Mouse Port
  • 1 x Keyboard Port
  • Front access

Note: Storing data from multiple data streams from a PMU / multiple data streams from multiple PMUs shall correspondingly reduce the number of days for which the data shall be archived.

Inputs:

VCL-PDC supports the following protocols:

  • IEEE C37.118-2005
  • IEE C37.118.2-2011
  • IEE C37.118 Draft 6
  • IEC 61850-90-5
  • IEEE 1344

  • Virtual Device.

Archived Output Formats:

VCL-PDC can be used to retrieve data from its archive / storage for event analysis and simulation in the following outputs:

  • CSV
  • COMTRADE ASCII
  • COMTRADE Binary

Monitoring:

  • Performance statistics are logged every 10 seconds and include latency, data quality, and time code errors as well as stream statistics for input and output streams.

Data Format and Coordinate Conversion:

  • Multiple outputs can be fully configured individually.

Scalability:

  • Distributed multi-node architecture supported for customers with need for high availability and throughput.
  • Role-based security for configuration management with configuration change logging for CIP compliance.
  • Administrator
  • Editor
  • Viewer

Utilities:

Three utilities are installed alongside Historian.

Data Migration Utility - Converts Historian 1.0 Archives to Historian 2.0 Format

Data Trending Tool - Queries Selected Historical Data for Visual Trending Using a Provided Date/Time Range.

Data Extraction Utility - Queries Selected Historian Data for Export to a CSV, ASCII or COMTRADE formats using a “Provided Date/Time Range” for easy data analysis.

PMU Connection Tester Utility:

The PMU Connection Tester Utility is included with the VCL-PDC. This Utility is a Windows GUI application used to validate, test and trouble‐shoot connections and data streams from phasor measurement devices as well as graphically visualize their Synchrophasor data in real‐time. The PMU Connection Tester verifies that the data stream from any known phasor measurement device is being received. Device types that can be tested through the PMU Connection Tester application may include:

  • Phasor Measurement Unit (PMU)
  • Phasor Data Concentrator (PDC)
  • Digital Fault Recorder (DFR)
  • Power Quality Meter (PQ)
