Abstract
In this paper, the topic of "Optimization design and energy efficiency improvement strategy of small hydropower Station" is discussed in depth how to achieve more efficient and environmentally friendly energy utilization of small hydropower station through scientific design optimization and energy efficiency improvement strategy. As an important part of renewable energy, small hydropower station has significant advantages such as low construction cost, zero pollution and renewable, which is of great significance for alleviating energy crisis and promoting sustainable development. However, due to the limitations of technical level, design planning and operation management, the power generation efficiency and operation stability of many small hydropower stations still need to be improved. This paper first analyzes the key problems in the design and operation of small hydropower station, including the selection of terrain and hydrological conditions, the performance matching of unit equipment, and the efficiency of water conservancy facilities. Then, a series of optimization design and energy efficiency improvement strategies are proposed. In the aspect of design optimization, the key factors such as selecting suitable terrain and hydrological conditions, optimizing reservoir design, rational layout of turbine and generator set are emphasized. In terms of energy efficiency improvement, it focuses on improving the energy efficiency of hydraulic facilities, updating and transforming aging equipment, strengthening efficiency expansion and other aspects, and reducing energy consumption and improving efficiency through the introduction of advanced technologies and management methods. This paper also discusses the trend of grid-connected operation and intelligent management of small hydropower stations, and emphasizes the important role of automation technology in improving the stability and efficiency of hydropower stations. By introducing automatic monitoring system and optimizing scheduling strategy, the intelligent operation of hydropower station is realized, and the power generation efficiency and operation safety are further improved. This paper provides systematic strategies and suggestions for the optimal design and energy efficiency improvement of small hydropower stations, aiming at promoting the development of small hydropower stations to be more efficient and more environmentally friendly. Through the implementation of these strategies, it can not only improve the power generation performance and economy of small hydropower stations, but also make positive contributions to the wide application of renewable energy and sustainable development.
