Development and Implementation of Energy-Saving Control Algorithms for Pumping Units of Power Plants to Increase Their Operational Quality

The work is dedicated to increasing the operational quality of pump units for the thermal and nuclear power plants in Ukraine, which are characterized by physical and moral aging. The problem is addressed through the development and implementation of energy-saving control algorithms for pump units that were realized at the Zmiiv Thermal Power Plant. A centrifugal-type circulation pump which supplies cooling water to the condenser is considered as an example of the implementation of the algorithm. The article presents mathematical models of pump operation modes, conducts experimental research on their characteristics to identify the proposed mathematical models, and determines the numerical parameters of energy-efficient control algorithms. Universal laws and algorithms for energy-efficient control of pump operation modes have been developed to achieve maximum efficiency values in their main operating modes, associated with reducing energy and fuel consumption for internal needs of power plants that is relevant to the United Nations Development Goals.
