Grid Simulator Programming in LabView

[Prime06]

Hi,

I am studying in an EV project and I built a hardware setup that contains a grid simulator and a battery setup. I want to control the NHR model 9410 grid simulator for both taking and giving power to the grid by giving the power input data into it. I can take power from the grid and give it to the batteries, but I cannot reverse the process. How can I program the LabView to accomplish this task?
Thank you

Unless you show us what you are doing, we cannot tell what you are doing wrong.

You are going to have to post your code AND include the NHR libraries. As there is no way for us to get the libraries or any other information, manuals, and etc. from NHR. As NHR does not give any of that out unless you can prove that you own a piece of their equipment.

NH Research has some of the worst LabVIEW support and worst customer support I have ever experienced in 40+ years.

Here is the example that we give power input to the simulator. The real question is I don't know how to reverse the direction of power from the batteries to the grid

Sorry, that VI is not helpful.

• Nothing has useful labels (What represents e.g. Batteries? Grid? Direction? etc.).
• What are the values in the file and what do they represent? (Why not attach that file too?)
• Your VI runs forever. Shouldn't it stop once it runs out of file values? (Hint auto-index on a FOR loop!)
• You are only interested in a single-column from the file, so why are you reading and treating it as 2D array instead of 1D array?
• Your sequence structure has no purpose. The same execution order is already determined by dataflow alone.
• Why so messy (hidden wires, excessive wire bends, etc.)
• Why do you have numbered steps using free labels, but no legend for what the steps mean?
• Why is the front panel and diagram maximized to the screen? Very annoying!
