rotate complex angle

[relayman357]

I am computing phasor values of voltage & current waveforms at each sample point along the waveforms.  I want to plot all of the resulting phasors, aligned to a-phase voltage.  To do this I simple need to multiply each phasor by unity at an angle that is the conjugate of the a-phase voltage angle at that point.  

Is there a way to create a polar shift operator 1@-arg(Va)?   

See attached Prime 8 file for how I'm doing it now (multiplying by the conjugate of Va and dividing by its magnitude).

thanks,

russ

This?

1*exp(-1j*t) makes it.

Hi ttokoro,   can you share the file showing how you plotted the phasors?

[ttokoro]

My file is Prime 9. You can copy and past one by one from P9 to P8.

How did you get the arrow heads on the phasors in your plot?  Thank you, i will try to convert.

One example here

I'd be interested to know what you are working on, I also deal with relay data. Comtrade files etc at work.

Hi ppal - i'm just playing around taking abc waveform data and converting to symmet, then clarke, and then dq0.  Trying to that is.  😉
