Multi‐port equivalent scheme for multi‐winding traction transformers

Abstract

Purpose

The purpose of this paper is to present a new type of equivalent scheme of multi‐winding transformers.

Design/methodology/approach

An inventory representation of relations between currents and flux linkages has been interpreted as a multi‐port purely inductive circuit.

Findings

An equivalent scheme in the form of a multi‐port circuit, and a method of its parameters determination from field computations.

Research limitations/implications

Core losses are not considered in the multi‐port equivalent scheme.

Practical implications

A new equivalent scheme could become a basic tool for modeling multi‐winding transformers.

Originality/value

The introduced multi‐port equivalent scheme eliminates disadvantages of classical T‐type equivalent scheme of transformers.
