Answer Question
abc-dq0 transformation confusion and PI tunning
Hi George ,
I am working with PV and STATCOM models where basically for reference I used d component for real power and q component for reactive power control and used PLL for synchronisation. According to several papers , the abc-dq0 transformation with PLL synchronisation should make the Volatge q component to track zero and voltage d component to some definite value . But from my simulations in PV as well as from STATCOM , its working in opposite way . So , I had a look in MATLAB directory for the transformation matrix and it seems the PSCAD trasnformation matrix works as abc-qd0 rather abc-dq0 . It would really help my research a lot if you can clarify my doughts with some exmples or explanation if possible .
And if possible could you please give me some PI tunning examples like Trial or error / Zigler Nicoles method in PSCAD file . I have few in MATLAB , but it would be a great help if I can have a look on PSCAD models.
Cheers
