DQ0-transformation: calculate active and reactive power from instantaneous voltage and current signals

The DQ0-transformation, or direct-quadrature-zero transformation, is a very useful tool for electric power engineers to transform AC waveforms into DC signals. In particular, for three-phase systems, the use of DC signals simplifies the calculations immensely. The DQ0-transformation is the product of the Clarke and Park transformation. The Clarke transformation converts the abc-phase-components to αβγ-components while…
