description: The topic of the final qualifying work: "The choice of the neutral grounding mode of the 35 kV network" The presented work is devoted to the analysis of the operation of the power supply network of the offshore oil platform with various methods of connecting the neutral and evaluating the operation of relay protection in case of single-phase earth faults in this system. Assigned tasks: 1. Study of the features of single-phase closures depending on the method of neutral connection. 2. Creation a computer model of the system. 3. Calculation of the main electrical quantities in the modes of isolated, compensated and grounded through a resistor neutral. According to the results give recommendations on the choice of the most suitable grounded mode. 4. Analysis of the relay protection operation for the selected grounding mode. The simulation was carried out in the "Simulink Matlab" software package, the results of which were used to calculate various options for grounding the network. The magnitude of the earth fault current and the overvoltages were estimated. Additionally, the consequences of non-selective automatic reclosure were simulated on the cable-overhead section of the line, which is contained in the power supply scheme. Based on the results of the study, a decision was made to switch from an isolated neutral to a low-resistance resistive ground. Consideration of the operation of relay protection for the selected method of grounding showed that selectivity and sensitivity to short circuits is provided in all considered options for operating the network.
