Comparison of Data Transmission using C37.118

UDP and IEC 61850-90-5 Unicast and MulticastSet-up at PG&E Proof of Concept (POC) Test facili ty:

Two PMUs measure the same voltage and current information

5PMU1 – Transmits using C37.118 through a substation PDC to aSuperPDC (SPDC)

5PMU6 – Transmits using 61850-90-5 directly to the SuperPDC

Application Service Data Units – One-to-one relationship between frame

and data units

Data unit is same as message size (301 bytes), One frame (<1524 bytes)

Not presented here: Set up to include multiple data units (ASDU) per frame

allowing repeated data to protect against loss of data

PMUs are streaming P Class data at 120 records (frames) per second

Interval of tests is 10 second (1200 records)

Phase angle for phase A voltage for both the C37.118 and 61850-90-5 PMUs

• The values track closely

• Note that the C 37.118 PMU is filtered through the substation PDC, 61850-90-5

values come directly from PMU

Frames received and missing frames statistics.5PMU6 only: P class ,configured for 120 fps - Expecting 1200 per 10s interval

• Blue is number of frames received.

• Red is the number of missing frames.

1. First Impairment - 1 in seven frames dropped for ~ 2 minutes2. Second Impairment - 7 duplicated packets are inserted after every 14th packet, for ~ 2 min (the

duplicated packets are out of sequence)

Conclusions

IGMP Version 3

Successful Multi-Vendor Demo

IEC 61850-90-5 Unicast and Multicast synchrophasor data transportusing production-grade PMUs and PDCs

Data transport through firewall and routers

Consistent Unicast and Multicast performance Multicast can reduce network traffic significantly

Consistent performance using IEC 61850-90-5 and C37.118

UDP Have verified configuration update file change tracking




Next Steps

Measuring various latencies throughout the Network, incl.

Switches

Routers

PDCs

PMU to PDCs -Testing and Measurements

Additional Network impairment cases Measurement of latencies under these conditions

Improving statistics

Continuing with Implementation Agreements TC 57 (asneeded and per test findings at PG&E POC Test facility)




Additional Note:

PMU Connection Tester available

http://pmuconnectiontester.codeplex.com/releases/view/87611

Allows selection of a specific network interface when using a TCPor UDP socket

Allows for specifying a multicast source IP for multicast

subscriptions for devices or systems that require this
