| Popis: |
The technical and economic indicators of introduction of new type of smoothing reactors are calculated considering the features of the operating conditions of traction power supply systems of direct current 3,5 kV. Based on the data provided by operating and installation organizations, an assessment was made of cost indicators of catenary system repairs.The main financial items were formed, on the basis of which the calculation of net income and net present value was carried out in order to determine the payback period of inv estment costs.The payback period based on the calculations (a little more than three years for equipment related to fixed assets with an assigned service life of twenty-five years) indicates a high level of investment attractiveness of a new type of smoothing reactor. The suggested method allows calculations using a large number of physical and operational parameters that affect the economic performance of the device. |
