IMPROVING THE QUALITY AND RELIABILITY OF POWER SUPPLY
Аннотация: the article discusses the key aspects of improving the quality and reliability of power supply, which are the most important conditions for the efficient operation of enterprises and the sustainable functioning of energy systems. Special attention is paid to technical, economic and organizational problems affecting the stability of energy supply.
Ключевые слова: power supply, reliability, equipment modernization, energy efficiency, automation, reserve capacities, power supply stability, voltage fluctuations, power grids.
Sustainable power supply is a key element in the effective organization of work processes that meet modern technological requirements and production dynamics. Given the constant evolution of requirements for the characteristics of products and equipment, it is important to understand what measures contribute to

improving the reliability of power grids and how this affects the optimization of the activities of the enterprise.
The stable quality of electricity plays a decisive role in ensuring reliable and efficient operation of both industrial enterprises and household facilities. Its meaning is manifested in the following aspects:
1. equipment reliability:
- Constant voltage reduces the risk of breakage and wear of electrical appliances.
- Preventing voltage drops will extend the service life of the equipment.
2. continuous operation of processes:
- Sustainable energy ensures uninterrupted operation of production lines, reduces the likelihood of downtime.
- Ensures the accuracy of high-tech systems and instruments.
3. increase security
- Prevention of short circuits, overheating and other emergency situations.
- Reduction of risks due to uncontrolled interruptions or voltage surges.
4. economic efficiency:
- Reduce the costs of repairing and replacing equipment.
- Optimize energy costs by eliminating costs and improving energy efficiency.
5. quality of products and services:
- Maintaining a constant voltage is very important for high-precision industries, where any vibrations can affect the quality of the product.
- Increase the competitiveness of the enterprise by reducing marriages and
failures.
6. environmental impact:
- Reduce energy consumption and rational use of resources.
- Reduce CO2 emissions while integrating energy-saving solutions.

Thus, the stable quality of electricity is the basis for reliable operation of systems, cost reduction, ensuring the safety and sustainable development of enterprises and society as a whole.
The quality of electricity directly depends on the stable transmission and the uniform distribution of voltage through the network. To increase the reliability of the power supply, the following main factors are taken into account:
- simplicity of system design,
- the ability to withstand excessive loads,
- ensuring uninterrupted operation,
- compliance with safety standards.
In industry, single-stage power lines with a minimum number of equipment are mainly used. Such systems are distinguished by Ease of repair and the possibility of modernization without stopping technological processes.
Each production workshop must be equipped with a transformer substation with a stabilizing device that evenly distributes the load from the energy transmission center. At the same time, the substation is obliged to meet all safety requirements, which is especially important for reliable operation.
To improve the quality of power supply at the enterprise, the following aspects must be taken into account:
1. equipment upgrade - installation of modern Transformers, voltage stabilizers and switchgear, use of equipment with high energy efficiency indicators.
2. optimization of the power supply scheme - the development of a simple and reliable network structure with a minimum number of elements, the use of backup power transmission lines to ensure uninterrupted operation.
3. control and control of energy supply - the introduction of Automatic Control and monitoring systems for the parameters of the power grid, the use of intelligent systems to promptly eliminate accidents and overloads.
4. ensuring the reliability of equipment - regular maintenance and diagnostics of power lines and appliances, implementation of planned and preventive repairs to reduce the risks of failure.

5. elimination of instability factors - installation of voltage stabilizers to avoid differences, reduction of reactive power through the use of compensatory devices.
6. improving safety - equipping equipment with mechanisms to protect against short circuits and overloads, conducting training of personnel on the rules of operation of electrical installations.
7. Energy Audit - periodic analysis of energy consumption to identify weak points and excess costs, the introduction of energy-saving technologies such as LED lighting and energy recovery systems.
Decentralization of energy sources - the installation of local transformer substations to reduce the load on the general network, the use of alternative energy sources, such as solar panels or wind generators, to increase the stability of the system.
The application of these measures will improve the stability, safety and economic efficiency of the enterprise's power supply system.
Improving the quality and reliability of power supply is a strategic task on which the stability of the work of enterprises, the safety of the population and the efficiency of energy systems as a whole depend. Modern approaches to solving this problem require the introduction of energy-saving technologies, constant updating of equipment and optimization of existing energy supply schemes.
The main success factor is a systematic approach that combines technical solutions, competent management and compliance with safety rules. The introduction of automated control systems, the development of backup capacities and the use of alternative energy sources will ensure a stable power supply, reduce energy consumption and reduce the costs of operating networks.
Successful implementation of these measures is impossible without the participation of qualified specialists, constant monitoring of the state of systems and long-term planning. Improving the reliability of power supply contributes not only to improving work processes, but also to reducing the environmental burden, which makes this task an important part of the sustainable development of society.
