Thanks for the responses. I believe the genset has a 110 kW, prime rated, Stamford End as per the following:
Surely, given the variable nature of the load and the fact that on average the load is between 35 kW - 40 kW with brief spikes up to 76 kW it would be more fuel efficient to have a...
Hi All,
I was wondering if somebody could help clarify the power ratings for a diesel generator for me. A vendor is trying to sell me this generator (I think it is all he has in stock...) and I am convinced that it is larger than what I require. I require a 80 kW prime generator to service a...
Hi All,
"Why? The engine will always run at (or close to) 1800 RPM". Well not necessarily that is why I posting the question.
We are exploring the option of using the engine in a variable speed configuration whereby the synchronous alternator is decoupled from the load by a back-to-back power...
Hi All,
I am analysis the performance of a Generac SD250 diesel engine (https://www.generac.com/Industrial/products/diesel-generators/configured/250kw-diesel-generator. Using info from the attached data sheet - including the hourly fuel consumption figures (l/hr) - I have managed to calculate...
Hi All,
Thanks for all the responses. Things me quickly on here...Some of them came in late last night and I only got back on site this morning, at which point I was able to make some progress with the meter. Following the instructions from XNUKE above I have been able to read data from the...
Hi xnuke,
Thanks for that. So if I use 9FC3 as the stating address and I enter the count as 6. Does that mean that the "Watts, 3-Ph total" address should be 9FC3?
Hi,
I am able to communicate with the power meter if I connect it directly to a laptop and run the ICC Modbus master tool. So I don't think there is anything wrong with the serial link. I just can't get the Accuenergy Data Acquisition Server to talk to the meter. It's definitely something with...
Hi All,
I am using an Accuenergy Data Acquisition Server (https://www.accuenergy.com/products/aculink-810-data-acquisition-gateway-server/) to log data from a number of power meters. Each of the power meters communicates with the Accuenergy via Modbus RTU. I am having trouble getting the...
Hi,
Sorry I did forget the attachment. I have added it. The CTs are at the Gen Breaker and there are no auxiliary loads. I'm guessing Whr-Delivered or Whr- Total would work...
Hi all,
I was hoping somebody could help me understand the difference between the parameters being read from an EATON IQ 100 Power meter. I am putting together a Modbus template to poll various parameters from the meter. The Modbus map is attached. The site we the meter is installed is a...
Thanks Guys.
itsmoked, that info is useful. The main thing that attracted me to the MEANWELL was the reasonable cost. LionelHutz I'm pretty sure the MEANWELL DRC-40B (described in the link) can be set up to provide a DC UPS system by adding a battery. It's clearly described in the datasheet...
Hi All, We have a number of data loggers deployed in the field recording data from various sensors. They all require 24 Volt DC power supplies and each draws about 950mA. To ensure that they keep running during interruptions to the mains I would like to connect them to a UPS.
I have found a...
Hi All,
I was hoping to get some advice on how I might communicate with an EATON IQ 100 power meter. The meter has an RS485 port and Modbus-RTU Protocol. The datasheet is attached if it helps. The meter is located in a generator room, unfortunately, there is no wifi or internet in that room...
Dear All,
I was hoping to get some tips on metering devices that could be used to monitor and log energy consumption in a small (150 kW) microgrid. Eaton IQ 100/200 series meters have been recommended. This is a remote microgrid but internet and mobile signal is available on site. Ideally, we...
