Computation Method for Unbalanced Heavy Current Circuit Electrical Parameters

Unbalanced heavy current circuit electrical parameters have serious negative effects on the operation of electric furnace. The V I relationship of unbalanced heavy current circuit was analyzed using electromagnetic and circuit theories. Equivalent parameters were derived from physical structure. A simple equivalent circuit was proposed using equivalent parameters and controlled sources. It could be used to calculate electric parameters conveniently. The sizes and relative positions of transmission lines could be optimized within the allowable space. A relatively accurate computation method for design and renovation of heavy current circuits was provided.
