Load flow analysis Load flow analysis vrdluchmun (Electrical) (OP) 23 Sep 16 21:16 I am using MATLAB to do a load flow of 8 bus but MATLAB does not recognize this formula- V(i) = pol2rect(abs(Vprev(i)), angle(V(i))) RE: Load flow analysis xnuke (Electrical) 25 Sep 16 01:02 MATLAB has no built-in conversion functions between rectangular and polar coordinates. You have to write your own pol2rect function. xnuke "Live and act within the limit of your knowledge and keep expanding it to the limit of your life." Ayn Rand, Atlas Shrugged.
