Micro-hydroelectric power station with a hydraulic unit regulation along a hydrogenerator anchor circuit

Abstract

Relevance. The article provides a comparative analysis of micro-hydroelectric power stations with a hydraulic unit regulation along a hydrogenerator anchor circuit according to technical and economic efficiency. The authors substantiate the possibility of using intelligent control of the energy balance of inverter micro-hydroelectric power stations for increasing the amount of electricity generated without increase in the installed capacity of the hydraulic unit. This will improve their technical and economic characteristics compared with traditional micro-hydroelectric power plants of the ballast type. This approach allows using intelligent control systems that can regulate power generation depending on the peaks of electricity consumption. For this purpose, inverter micro-hydroelectric power stations are used. They allow more efficient management of energy consumption and accumulation of electricity in batteries. The developed control algorithms make it possible to optimize the operation of micro-hydroelectric power stations, ensuring maximum resource efficiency and reducing the cost of electric energy. Application of these technologies may significantly improve economic indicators of micro-hydroelectric power stations and make them more competitive in the electricity market. The algorithms control the hydraulic unit operation, ensure supply of electric power to consumers and effective use of energy storage batteries depending on electric needs. Aim.
