Особливості визначення енергетичного балансу гібридних локомотивів

Abstract

The energy balance of a locomotive is based on the law of energy conservation and includes an income and expenditure component. For hybrid locomotives, the income component includes energy received from all independent sources, such as diesel generators and the overhead power network. Energy storage systems play a key role in conserving energy for additional traction or autonomous operation, as seen in hybrid electric locomotives operating on non-electrified sections of tracks. In diesel locomotives, thermal energy storage can be utilized for heating and preheating the cooling system of the diesel engine, which helps reduce fuel consumption during winter. It is proposed to account for the energy of storage systems in the expenditure component of the balance, considering energy losses during conversion and storage.
