Improvement of the cooling system of reactive power compensating devices used in railway power supply

This article analyzes the reactive power generation and compensation solutions in the "Uzbekistan Railways" electrical supply system operating at 25kV, 50Hz frequency. It examines the efficiency and economic analysis of the cooling system connected to the control components (thyristors) of the device compensating reactive power under various operating conditions. The study compares the conventional cooling system approach with the newly researched cooling system for the controlling components of reactive power compensation. It proposes specific systematic solutions regarding the electric locomotive's load current, environmental conditions, reliability of the cooling system, maintenance capabilities of the cooling system, and real-time monitoring and control analysis delivery to the service provider. Additionally, conclusions are drawn regarding the economic and energy efficiency.
