Features of iPDC 

It is a generalized PDC.

Is a multithreaded application.

Page 13: Design & implementation of phasor data concentrator compliant to ieee c37.118 synchrophasor standard in wide area measurement system

   

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.

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.
