LORaWAN Metering Solution -University Campus Wide LoRaWANWireless Energy Monitoring

The design of the busduct system makes it easy to detect abnormalities during installations and ensures easymaintenance. When humidity or dust causes a malfunction on the system, the easy to maintain design allows replacingonly the damaged parts.

Project Scope

 The trial project was started in early 2017. CET has to...

(1) Prove that its PQ monitor (PMC-680i) complies with all PQ measurement requirements
(2) Support data transmission from PQ monitors installed at remote substations to the PQ monitoring software through Ethernet, twisted pair wires or wireless solution
(3) Supply an Open System (PecStar iEMS) to integrate the existing 500 PQ monitors throughout the network and demonstrate the ability to integrate PQ monitors from different suppliers
(4) Send a notification Email & SMS within 60s after the occurrence of a PQ event
(5) Generate predefined PQ reports for performance evaluation

Solution & Result

 CET provided the solution for connecting the remote meters through different 3G networks. Given cost constraint, 3G APN network with private IP was recommended, instead of using static public IP. In considering the instability of signal strength, CET suggested to use the meters with data logging capabilities (PMC-630E), which could store data in non-volatile memory to avoid data loss in case of connection failure.
