Комп’ютерно-орієнтована математична модель оцінки ефективності тарифної системи оплати за спожиту електроенергію залізницею

Abstract

Market conditions and, in particular, the possibility of paying electricity for the various tariffs allow railroad as a large consumer significantly save costs by using the optimal tariff system for each railroad’s electrified areas. The research of issue tariff assessment in the current circumstances, with no capacity changes, which will apply more advantageous tariff system without additional material expenses, is devoted. The mathematical model of assess use’s effectiveness of the differentiated tariffs electricity payment is developed. The analysis of electric energy consumption for railway traction needs is performed and, for example, the use of a mathematical model at specific conditions is shown. The analysis of electric energy consumption by electrified railway area has found, that using of differentiated three-zone tariff is not advantageous for all cases without changing schedule of the trains traffic. Using of developed mathematical model to determine the effectiveness of application differentiated tariffs electricity payment is suggested.
