Product Number: ADE9430

Hi,

I am actually trying to get THD values using PQ library of ADE9430. I am integrating with my TI controller. I am facing issue regarding the flow of my execution. Value of "waveformBlockIdx" is compared withetc pq values. "PQLIB_NUM_WAVEFORM_BLOCKS" but but it never reaches to that value and becomes "0".
Please can i get an explanation of how this PQ calculation works so that I can get THD etc PQ values.

The library APIs should be called in predefined sequence as explained in the API documentation given in the package. It is recommended to run the example code on the evaluation board to understand the flow and the use of APIs before porting to a different processor/platform.

Is it possible for you to share a flow chart for understanding a basic flow for PQ calculations emphasizing Harmonics calculations?

Section 5.2, 5.3, and 5.4 of Power Quality Library User's Guide provides sequence diagrams for the API calls. The library is designed to be used with documented APIs and contains some proprietary algorithms. Documentation of those algorithms are not available for the users now.
