The aim of this study is to solve the problem of increasing the efficiency of fuel and energy complex enterprises. Because such enterprises are complex systems, it is difficult to optimize their work, taking into account all the technical indicators of such enterprises. This study proposes to solve this problem by defining an algorithm using the data envelopment analysis (DEA) method. In particular, the algorithm was applied in heating systems using the example of a combined heat and power plant, where the DEA method had not previously been used. Experiments were carried out to improve the efficiency of the combined heat and power plant. Efficiency indicators were calculated, changing inputs and outputs of the model according to the study case to achieve the maximum efficiency of the system. The Charnes; Cooper and Rhodes; and the Banker, Charnes, and Cooper models were tested with good results. The presented methodology and experimental results enabled the DEA method to be applied for the first time to improve the efficiency of fuel and energy companies.

The article proposes the DEA method to solve the problem of estimating the efficiency of the heat supply system in Krasnoyarsk, where several enterprises provide heat supply services. The architecture of the universal DSS has been modified using the DEA method. The application of DSS with such architecture made it possible to make more informed decisions regarding the estimation of the enterprise safety with respect to the environment. The article also shows the efficiency of the DEA method in solving the problem of estimating the efficiency of the heating system in Krasnoyarsk. The features of using this method in decision support systems are given.

В статье описан параметрический метод анализа охвата данных, применяемый для оценки эффективности объектов. Также рассмотрена модель CCR для оценки эффективности сложных систем. Коме этого рассмотрены ее теоретические особенности, а также практическое применение в мировой литературе. В статье проведена апробация метода охвата данных и модели CCR для предприятий топливно-энергетического комплекса. Также проведены эксперименты расчета эффективности функционирования предприятий системы центрального коммунального теплоснабжения на примере теплоэлектроцентралей. Кроме этого, на основе данных входов и выходов работы предприятий, рассчитаны показатели эффективности для исследуемой выборки. Выявлены неэффективные предприятия. В статье рассчитаны показатели входов и выходов исследуемых предприятий для повышения их эффективности. А также даны рекомендации по настройке эффективности теплоэлектроцентралей за счет корректировки показателей входов и выходов. Полученные в статье экспериментальные данные могут быть использованы для повышения эффективности предприятий топливно-энергетического комплекса. Полученные данные могут быть использованы в академической сфере, а также имеют практическое применение для теплоэлектроцентралей. Кроме этого, на основе полученных в статье данных в дальнейшем будет построен алгоритм для системы поддержки принятия решений.

The method of control of a pump motor using a frequency converter as the most promising for saving energy in pumping units is described in the article. The installation of a two-transformer circuit with a low-voltage frequency converter at a pumping station in Krasnoyarsk with three network pumps equipped with DASO4-450X high-voltage asynchronous electric motors with a power of 630 kW and a voltage of 6 kV was also tested. The introduction of a two-transformer circuit and a low-voltage frequency converter with the inclusion of a sinus filter reduces the energy costs by 37%, reduces the temperature of the entire pump unit to 44 ° C and reduces the number of stops by 10%. In addition, the use of a frequency converter allows to increase the reliability of the entire system, as well as to reduce the risk of a breakthrough of the pipeline network, which is achieved by automatically maintaining pressure within the specified limits.
