Abstract

The article is devoted to identifying the features of application the Analytic Hierarchy Process (AHP) when choosing the modernization strategies to thermal power plant (TPP) subsystems and convert TPP into an energy technological complex (ETC). Criteria for evaluating the effectiveness of alternative energy projects are presented. It is shown that the use of optimization methods makes it possible to reduce the influence of the subjectivity of the decision maker (DM) at the upper levels of the hierarchy. The method of parallel hierarchies is proposed, which allows in one model to take into account the influence of non-subordinate tasks and problems of energy production.

Highlights

  • There are a number of problems at thermal energy facilities in Russia, such as thermal power plants, centralized heat supply boilers: the moral and physical deterioration of equipment, the need to use the coal of degraded quality, the accumulation of ash and slag waste, increasing demands on the composition and temperature of flue gases

  • Projects of equipment and technologies with higher efficiency have been developed in Russia and other countries of the world, allowing the separation and utilization of ash and slag materials (ASM), taking into account their physical and chemical properties, which allow cooling downstream gases dispose of acid oxides contained in them

  • We accept restrictions: the choice strategy is determined by the owner of the thermal power plant (TPP) or the modernization investor, for which the priority is minimizing financial investments and risks while maximizing profits and the competitiveness of products; it operates within the framework of the legal field of the Russian Federation; finances only production and does not seek to invest his money in the development of science, he chooses known technologies and serially produced equipment; the owner / investor has his own political interests in the region where the TPP is located, and strives to create a favorable social background by creating new jobs

Summary

Introduction

There are a number of problems at thermal energy facilities in Russia, such as thermal power plants, centralized heat supply boilers: the moral and physical deterioration of equipment, the need to use the coal of degraded quality, the accumulation of ash and slag waste, increasing demands on the composition and temperature of flue gases. These problems need to be addressed when modernizing existing thermal power plants and designing new ones. This article presents the results of the author’s research on the choice of strategies for coal-fired TPP subsystems modernization (fuel preparation, oxidizer preparation, separation and recycling of ash-and-slag materials, utilization of flue gas heat and components) and modernization of thermal power plants as a whole using the AHP, features of the AHP application to the choice of modernization strategy for the industrial energy facilities identified and analyzed

The method of AHP application
Modernization of the fuel preparation system at the coal power plant
Modernization of the oxidizer preparation system at TPPs
A50 A99 A21 Amount by column
