MATHEMATIC SIMULATION OF TRANSIENT PROCESS IN A. C – SYSTEM “ELECTRIC – TRACTION – NETWORK – LOCOMOTIVE” 2. SWITCH ON THE MAIN LOCOMOTIVE’S POWER CONVERTER IN “FREE PAY” MODE; DEFINITION AND ANALYSIS CURRENT SURGE OF MAGNETIZATION

Abstract

The article is a continuation of analysis of mathematical models for AC systems, in which the elements of electric-traction network and switch-on of power transformer in an idling mode are gradually connected. The numerical calculations and analysis of current of transformer magnetization are executed.
