Retrieving Dynamic Generator Outputs

Does anyone know of a way to retrieve the generator power (real and reactive) outputs during dynamics in PSSE 32?

I have tried the macdat and macdt2 API's, and it seems like these are only for power flow values as they always produce the same results no matter the dynamic event.

I also know of the chval API method where I make gen power a channel value. Unfortunately, this is not really an option for me as I am trying to make a generic function for every machine in my model and this would require me adding thousands of channel values extra as this is a relatively large model.

I can't seem to find anything else in the API manual for this.

Thanks.

Carter, thanks for the suggestion. Unfortunately chsb adds the real/reactive powers to the output channel file. I would like to avoid doing this for reasons stated above.

Hi, did you solve this problem? How to return the data into a variable and don't output the data into a channel file?

Hey Jacde,

I believe you can use the chsb API, it allows you to track a large amount of variables during dynamic simulations. An example to keep track of real and reactive power using chsb is shown below:

psspy.chsb(0,1,[-1,-1,-1,1,2,0]) #Keep track of real power psspy.chsb(0,1,[-1,-1,-1,1,3,0]) #Keep track of reactive power

I just remember that there is MVAR that shows minimum and maximum reactive output power that the generator can output. I have no idea if there is informaton about retrieve output.
