Estimation of the Primary Current in a Saturated Transformer
1991 (English)In: Proceedings of the 30th IEEE Conference on Decision and Control, 1991, 2363-2365 vol.3 p.Conference paper (Refereed)
It is pointed out that, when a current in a power system is measured using a transformer, the measurement can be distorted by transformer saturation. The authors examine two methods of estimating the primary current from the secondary in the presence of saturation. The first is based on an extended Kalman filter, while the second is based on an off-line Gauss-Newton method
