PRIME stands for PoweRline Intelligent Metering Evolution:

It is a PLC protocol used for Smart Grid and Smart Metering

mainly to support massive meter reading & management.

It was designed as a future-proof solution:

State-of-the-art.

Economies of scale (open, interoperable).

PRIME is a Telecommunication Standard: Annex B of ITU G.9955 & 9956.

PRIME is now a specification under the umbrella of the PRIME Alliance registered as a Belgian non-profit association(http://www.prime-alliance.org/), a group of companies working together to develop PRIME interoperable solutions.

≡ First Large Smart metering PRIME program: “STAR” project

≡ Location with 100,000 meters (175,000 inhabitants)

Deployment of PLC PRIME meters

≡ Up to 600 secondary substations

Various WAN solutions:

PLC over MV, GPRS, ADSL, optical fiber…

PRIME sub-network evolution: meters availability at PRIME protocol level

• Meter availability is a measure of PRIME network performance

Connected meters

Number of switches

TIME (1 week)

99.55% PRIME availability


Performance Monitoring: “Short and Long cycles” availability

22

• “Short cycles” : DLMS/COSEM messages cycles between meter and DC to collect basic meter parameters

• “Long cycles” : DLMS/COSEM messages cycles between meter and DC to collect full meter parameters

Short cycles availability

Long cycles availability

Meters (2 days continuous metering data collection)

Each meter was able to successfully complete the 98% of short cycles requests

Each meter was able to successfully complete the 96% of long cycles requests

Short/Long cycles availability are a measure of AMI performance:
