Abstract
The currently used three-phase models [1-3] of transformers with delta -connected windings may lead to three- phase fundamental and harmonic bus admittance matrices of power systems with singularity, which may r esult in incorrect results or inability to carry out three- phase fund amental and/or harmonic load flow solutions. In order to solve this pr oblem, this paper presents a modified model to keep the admittance mat rices from singularity. Several samples and actual systems have proved the correctness and efficiency of the proposed model.
