Abstract

Internal model control (IMC) method enables the system to be of good dynamic and steady performance, which is simple, and is easy to be implemented. In allusion to the cascade STATCOM feature of high order, instability, multi-variable, non-linearity and tight coupling, the mathematical model of cascade STATCOM in d-q-0 coordinates was deduced. Decoupling model of cascade STATCOM was given by Internal Model Control principle, computer simulation and experiment results were also given. Results show that with IMC, 3-phase currents control method of cascade STATCOM has good tracking performance and control precision both in a-b-c coordinates and in d-q-0 coordinates, and also achieves excellent current compensation results. DOI : http://dx.doi.org/10.11591/telkomnika.v12i3.4452

Abstract

A reference currentdetection algorithm based on synchronous reference frame transformation and discrete Fourier transformation is presented for STATCOM (Static SynchronousCompensator) to provide synthetic compensation. The proposed algorithm can be used to extract reactive currents, unbalanced currents and characteristic harmonic currents from the load currents in real time. This algorithm allows the simultaneous compensation of two current harmonics with just one regulator, yieldinga significant reduction of the computational effort compared with other methods. The results of simulation and experiment show the validity of this method DOI : http://dx.doi.org/10.11591/telkomnika.v12i3.4451
