In certain areas, only stand-alone power generation systems can be used, as it is impractical and unprofitable to lay power grids in these areas. Such systems are usually based on a combination of wind or hydro turbines, drive motors and electric generators. It is characterised by high reliability, long service life, low cost and ease of maintenance. In times of military emergency, the operation of autonomous systems can be critical for people's lives and communication with the outside world. In addition, in such systems, the main con-sumers of electricity do not use the entire resource of energy generated by the wind turbine. Therefore, the issue of redistributing excess energy is relevant and can be solved by connecting a water supply system to provide ad-ditional potable water to consumers. At the same time, pressure instability in the hydraulic water supply network can worsen living conditions and lead to accidents and disruptions in technological processes.In connection with these challenges, there is a need to measure and stabilise the pressure in the hydraulic network, which can be done using observers of technological coordinates developed on the basis of the theory of artificial neural networks. The paper proposes a modern electromechanical control system for a turbomechanism powered by an alternative source of electrical energy, with a focus on stabilising the pressure in a hydraulic network using a pressure observer.A mathematical description of the main elements of the investigated system is given. The pressure estimator of the hydraulic network is built on the basis of artificial neural networks with a modified structure with feedback. The paper considers the operation of a sensorless pressure stabilisation system during changes in hydraulic re-sistance within the daily water consumption cycle with redistribution of excess energy generated by a wind tur-bine. The results and analysis of the developed estimator in sensorless control systems powered by a wind turbine with an electronic load controller are presented. |
