More Information
Summary:In order to improve the ability of transformer differential protection in the inrush identification, this paper proposes an algorithm based on the magnetic transient for internal fault simulation of single-phase transformer. A new fitting method for the hysteresis loop of transformer based on support vector machine is set forth, which is original optimization of the hysteresis loop test data regression translates into the allelomorph optimization. According to the fractal characteristic of local hysteresis loop, a search for internal fault simulation of single phase transformer is put forward .The application of the proposed algorithm to a test system shows its validity
