| Summary: | The intensification of geological exploration works is crucial for the sustainable development of mineral resource use in Ukraine. This is impossible without a significant increase in drilling volumes. Solar energy sources are an актуальний trend in energy supply development and a technical solution with great potential. On the other hand, electrical rotating motors are used in drilling equipment as winches and drives for rotary mechanisms. Since geological exploration works are often carried out in areas that may lack grid electricity, it is logical to conclude that such motors require autonomous power sources. Photovoltaic power sources enable quick deployment of drilling equipment and ensure their mobility. To combine drilling equipment with photovoltaic power sources, a modeling device is advisable. An electrical model of the system, consisting of photovoltaic panels, a battery, a booster, and a DC motor, has been created. It is shown that it is beneficial to use DC motors with dependent excitation winding, which is connected in series with the armature. The corresponding electrical model has been built, and equations for calculating the electrical model of the proposed system are presented. It is noted that a controller is used to regulate the electrical parameters of the photovoltaic power source, and dynamic control of the photovoltaic array configuration is also possible by dynamically controlling the parallel and series connections of the panels in the array. It is shown that the mechanical load on the drill rig rotor is nonlinear. Corresponding mechanical and electrical equations considering nonlinearity are presented. Conclusions are made, and further development is outlined. |
