Determination of Parameters for Plug-in Hybrid Power Plant for a Shunting and Haulage Locomotive for Industrial Enterprises

Abstract

Purpose. The purpose of the article is to determine the parameters of a plug-in hybrid power plant for a shunting and haulage locomotive for industrial enterprises. Methodology. An analysis of the parameters of the operating modes of diesel locomotives used for shunting operations and haulage work at domestic industrial enterprises was carried out. Data from the on-board systems of diesel locomotives operated by PJSC Poltava Mining and Processing Plant and PJSC DTEK Pavlogradvuhillya were used for the analysis. Finding. It was determined that during shunting operations, energy consumption does not exceed 600 kWh at a maximum power of 350 kW. During haulage operations, energy consumption is 850–1200 kWh at a maximum power of 650 kW. A comparison of fuel consumption, fuel and energy costs, and CO2 emissions for different power plant options was carried out. The fuel characteristics of Cummins QST30–L2 diesel engines with a power of 895 kW and Cummins QSZ13 diesel engines with a power of 401 kW were used for a comparative assessment of hybrid power plant options. It was found that it is rational to use plug-in power plants in which the energy storage device must be charged from an energy source with a low cost per kilowatt-hour of energy. This allows reducing fuel and energy costs by 30–35% compared to diesel fuel costs when performing maneuvering operations. To ensure export operation, the plug-in hybrid power plant must include a diesel engine with a capacity of about 400 kW. In this case, the traction electric drive and auxiliary systems are powered jointly, and the possible reduction in fuel and energy costs can be 12–14%. It has been shown that the type of storage cell should be selected taking into account their service life. For the plug-in power plant under study, it is rational to use CALB L194F130B lithium iron phosphate cells. Originality. The use of a plug-in hybrid power plant on shunting and haulage locomotives used in industrial enterprises has been justified, and the parameters of the power plant have been determined. Practical value. The results obtained can be used in the creation of hybrid power units for shunting and haulage locomotives for industrial enterprises. The proposed method for determining the parameters of a hybrid power unit can be used for other rolling stock.
