to Energy Disaggregation

Hi All,

At Navetas we have developed a number of systems for multi channel data gathering for the purposes of disaggregation research and storage.

We no longer have a requirement for some of the systems and so they are looking for new home. The specification is below, but if you are interested in finding out more, then please give me a shout and I can provide you more details. They've been built to a high spec and are designed specifically to overcome the challenges in gathering aggregated and sub-metered validation data simultaneously. They've currently configured for US data gathering (2 channel voltage, 60hz base frequency) but anyone who is familiar with lab view and national instruments would be able to modify the source code to their own needs for other countries (including the UK.) Equally, if you have any questions about whether the kits could be re-purposed for your application, then feel free to drop me a note.

We've got 19 of the systems available. They've been fully refurbished and tested since being removed from the field and are in tip-top order. I've attached a picture (with lid removed) to give you an idea of what they look like.

Thanks,

Jim

System Overview

The system has been custom designed for the particular needs of electrical data acquisition for disaggregation. As configured, it features the ability to acquire 2 high frequency voltage and current channels at 8khz whilst simultaneously measuring 36 current channels at up to 60hz for the purpose of sub metering validation.

All data is acquired simultaneously, resampled, and stored to a network attached 3Tb hardrive in RAID 1 (mirrored) configuration.

Finally the system contains a network switch and wifi router to allow for NTP synchronisation (to allow accurate timestamping of data), remote diagnostics and firmware update.

Navetas has successfully used these systems in the US since 2013 years with typical installation periods being 3-6 months.

Each data acquisition system is based around the National Instruments Compact Rio 9076 (http://sine.ni.com/nips/cds/view/p/lang/en/nid/209758) , with 3 * NI9205 32Ch +-10V analog input modules (http://sine.ni.com/nips/cds/view/p/lang/en/nid/208800) and a single 9225 3Ch 300VRMS isolated analog input module (http://sine.ni.com/nips/cds/view/p/lang/en/nid/208795)

Therefore, the system could be easily re-configured via LabView to provide different sample rates or functionality as required.
