How to get a load profile 2

[analystuc]

Please I am not conversant with electrical systems. But I was asked by a power plant vendor to provide an electrical load profile for a fertiliser plant to enable them to select an appropriate power plant configuration. How and where do I start from.

@ waross
Thanks for your suggestion anyway. I guess one pays for this kind of thing. But I would still appreciate a little insight into the process of getting a load profile. Maybe a pinch of information would set me on the right track towards getting consultant help.

Electrical power demand varies over each day and throughout the year.

In the case of a cogeneration facility, I expect they will want to know the peak power demand each month for the past year as well as the kWh and kVarh usage for each month over the past year or two. Some of this data can probably be obtained from the power company, some from the local plant metering, and some may have to be obtained via use of portable power monitoring equipment.

A load profile is a description of the electrical load for the facility under various operating conditions: startup, standby, full capacity,etc. It lists the magnitude and duration of the loads. If the plant is existing, record the actual loads for a month or more at the utility service, noting peak KW, average KW and other factors, such as size of largest motor.

If the plant is under design, determine the size of all electrical motors and loads in the plant and when they will be running. Sum the loads that are running for each different operating mode and determine how long each mode will last. Develop a chart or graph or table showing the various loads and timing.

The power plant personnel want to know how much power the fertilizer plant will need under all operating conditions and how long each condition lasts. The peak load requirement determines the size of the generating plant. The average load determines if there is enough revenue to cover capital costs.

Start by gathering all of the individual load data and a description of how the plant operates. Then hire a knowledgeable consultant.

I appreciate your reply. I guess peopla are paid for this sort of thing.But I would really appreciate any snippet of information for a headstart. This would make things easier when looking for a consultant.

I think you have several snippets already.

If the plant is existing, the plant owners can get it from the utility company.

If not, find "fertilizer plant consultants'.

Thanks a bunch all. am grateful.
