| Özet |
| In this paper, a state estimation based method is proposed to determine harmonic current contributions of iron and steel (I&S) plants supplied from a Point of Common Coupling (PCC). Due to highly nonlinear nature of the iron and steel plant operation, accurate estimation of the harmonic contributions of the individual plants is essential. In the proposed method, the nonlinear characteristics of the plants and the utility are modeled as harmonic current sources and the harmonic current contributions of loads are decoupled from the upstream effects on the basis of the sample-by-sample time-synchronized field measurements of load currents and voltage signals. Being a field-measurement-based method, it is necessary to mitigate the measurement errors of conventional voltage transformers at harmonic frequencies. Gross error of voltage transformers is reduced through calibration, while weighted least squares state … |
