Improving the efficiency of a water supply enterprise through the development of an automatic control model for pump units

Abstract

Relevance: with the rise of urbanization and accelerated industrialization, global energy demand has significantly increased. In 2021, the world’s electricity consumption amounted to 27,000 terawatt-hours, and this figure is growing at an average rate of 2.7% per year. According to the International Energy Agency, global energy consumption is projected to increase by 40% by 2040.

To further accelerate efforts to provide the population of our republic with clean and high-quality drinking water and improve wastewater services, as well as to create decent living conditions and preserve public health through increased coverage of drinking water and wastewater services, the President's Decree - According to the New Uzbekistan Development Strategy for 2022-2026, approved by Decree No. 60 of January 28, 2022, the level of drinking water supply coverage in the republic is 87%, with plans to upgrade the wastewater systems in 32 major cities and 155 districts. Generally, most of the pump stations operating in our country are equipped with fixed-speed, or single-speed, electric motors. Pumping units in water supply enterprises mainly operate with variable loads, leading to the use of motors with adjustable or multi-speed settings in the field. The use of energy-efficient electric motors with adjustable speed and innovative control methods serves to enhance the efficiency of pump stations.

Aim:  develop and implement a new model of automatic control for pump units to enhance the efficiency of water supply enterprises. This involves improving energy efficiency, enhancing system performance, and optimizing the operation of the water supply system through the automation of pump unit operations.

Methods: the model for automatic control of pump units was developed using fuzzy logic methods and Mamdani decision-making methods.

Results: the model, developed based on fuzzy logic methods, allows for managing pump units at different speeds according to water consumption requirements, thereby enhancing the efficiency of water supply enterprises.
