Harmonic current flow using the admittance matrix method

A new age is dawning in engineering software. For the first time individual power system engineers can write their own software to do complex analysis rather than relying on software vendors. This is made possible by the introduction into the software marketplace of interactive graphic software which allows complex calculations to be done in symbolic form rather than in software code form. This reduces the time required to create calculation software to a fraction of that previously required. An additional advantage of this software is that it has an open architecture which allows modifications by other users. Users can alter the program as desired to be compatible with other software programs or to achieve specific desired results. This paper is an example of one program written in this symbolic software which calculates harmonic current flow using the admittance matrix method
