description: The objectives of this work are exploration the problem of voltage dips during the operation of drilling rigs in networks with limited power; exploration of re serve power supplies; selection and justification of the optimal backup power source for the reliable operation of the drilling rig ; construction of a mathematical model of the electrical complex of the drilling rig in the Matlab Simulink program. Methods: Matlab Simulink software was used to simulate the electrical complex of the drilling rig. Results: mathematical models of power systems were developed with two types of AC electric motors most common in the mining industry with their own control systems in the Matlab Simulink software package. A comparison There was a comparison made between the backup power sources, namely the diesel generator set and the storage battery. As the operating modes, the electric motor acceleration mode was chosen, characterize d by large starting currents and, accordingly, voltage fall and the alternating load surge mode, which corresponds to the stuck of the drill head in the soil in real conditions
