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