i’m an italian mechanical engineering student and i’m working on my thesis about energy efficiency and energy management. I’ve some budget to buy a system of hardware to build up an energy monitoring system, but i need some informations and advices from you.
Our university is divided in some departments, located all over the city of Viterbo. I want to track 6 departments. Now we check the electrical consumptions with 6 different PODs that send informations to the distributor and we can download from the distributor’s website all the datas in .csv (hourly consumptions in kWh + reactive power).
Every department is composed of 3 or more buildings and has 1 electrical panel. I need a way to track all the electrical consumptions divided in these 6 departments; in addition to that i want to divide only 1 sample departments in “buildings”.
So i have for example:
5 areas located in different points of the city + 3 areas located in the same point and with the same electrical panel but differents electric cables (i can split up the building in 3 areas - buildings - and sum it later in the software)
Every department has a free wifi and we have a internal network. Can I send informations and datas through this network?
We have both 380 V (3-phase) and 230 V (1-phase) AC current - 50Hz.
The question is: how can i this system? Which hardware i have to buy for each “area” (5 areas in different points + 3 in the same point) and which hardware i need to collect all the datas and send them to the CMS?
Do I need only 6 emon-Pi + 8 current sensors maybe?
