Features of iPDC
It is a generalized PDC.
Is a multithreaded application.
Cont....
It is built on Open Source platform and released under GPL v3.
Compliant to IEEEC37.118 Standards.
Support for both TCP and UDP communication Protocols.
Each received packet is authenticated.
Integrity of the packet is verified.
Provides local storage of data.
A GUI to setup PMUPDC and PDCPDC connection.
iPDC Design
Handling configuration frames
Handling change in PMU/iPDC Configuration frame
Recreate configuration objects from file cfg.bin
Handling Data Frames
Check Stat Word of data frames
Time Aligning of Data Frames
Sorting of Data Frames inside TSB
Configuration Frame Generation for iPDC
Number of PMU is sum of all PMU.
Data rate is the highest among all PMU/iPDC data rate.
Combined configuration frame compliant with IEEEC37.118 std.
Data Storage
iPDC Database

Results
iPDC Interface
Future Enhancements
Need to study and implement iPDC on RTOS and check its performance & scalability in Real Time.
Different aspects of security in WAMS need to studied and implemented.
On field testing of iPDC application need to be done to know its performance & limitations.
iPDC can be updated to support more PMU standards.
