Varible Speed Pump Control

Have you done a google search already?
I am not an expert on this matter, but I would say first of all that with a VSD pump there is obviously no control valve. Depending what parameter you want to control, like level, flow or pressure, I would imagine that you have a measuring sensor, like a flowmeter, level meter, that goes to the pump driver to manipulate the driver speed.

thousand barrels of water per day??
Nowadays my learned electrical friends say that a VSD is actually a variable voltage, variable frequency drive.
Is this homework?
There is no information at all on what you are trying to do. Injecting into the ground, injecting water in to a process, are you trying to maintain a constant flow, or a variable flow, or a constant pressure? what type of pump is it?
But you need a measured variable and then you modify the pump speed. You may need to start or stop pumps depending on the system and pump parameters.

Hi,
For info. there is a section untitled:"control scheme for VSD pumps" in the september 2009 issue of Hydrocarbon Processing magazine: "Applying pumps with variable speed drivers".
"We don't believe things because they are true, things are true because we believe them."
