Romanova K. Improving energy-ecological efficiency of operation of energy facilities by identifying the actual state of equipment

Dissertation for a Candidate Degree in Technical Sciences, speciality 21.06.01 – ecological safety. – Scientific Research Institution "Ukrainian Scientific Research Institute of Ecological Problems", Kharkov, 2019. The dissertation is devoted to improvement of energy - ecological efficiency and reliability of operation of environmentally dangerous power equipment and efficiency of estimation of its real state through the implementation of methodology of complex parametric identification of actual characteristics, which improves the accuracy of monitoring of technological parameters and characteristics and allows to detect early stages of work. gauges, track uncontrolled "runs" of parameters and with to realize energy-ecological optimization of loading of equipment and terms of carrying out repairs of units with prevention of emergencies while ensuring high level of ecological safety and efficient operation of equipment at the energy object (EO). The comparison with the existing regular monitoring systems made it possible to prove the expediency and necessity of development and implementation of the KPIFC methodology of units capable of fulfilling the assigned functions of increasing the energy and environmental efficiency of EO. A universal approach has been developed to identify the actual performance of the units opens the opportunity to improve existing methods of analysis and determine the performance of heat engineering processes in thermal power plants and the implementation of automated control of loading equipment in optimal mode. Recommendations for the operation of installations with high energy-environmental performance at different load modes in real time were implemented using practical and reliable research analysis methods. Complex energy-ecological analysis using parametric identification of actual characteristics of EO has been developed and implemented; algorithms, flowcharts, and methods for determining the performance of an energy object on the example of a gas-pumping unit on a boiler, software for software-analytical complex of actual characteristics; real testing of the methodology with obtaining permission for its introduction into industrial operation on real energy objects.
