description: The topic of the final qualifying work: "Accounting for grid parameters changes for evaluating the success of self-start of electric motors for power plantâs own needs". In this work the influence of changes in grid parameters are considered for evaluating the success of self-start of electric motors for power plantâs own needs. During the work, the following tasks were considered: 1. Analysis of the main scheme of electrical connections of the power plant and the system of own needs. 2. Analysis of self-start scenarios. 3. Calculation of the run-out of electric motors. 4. Calculation of parameters of substitution schemes for each scenario. 5. Calculation of self-start according simplified and refined methods. 6. Comparison of the performed calculations and conclusions. According to the results of the calculations performed using two methods, the deviation of the initial voltage on the sections of own needs was not more than 5%. This shows that accounting for grid parameters changes does not greatly affect the assessment of the success of self-starting of electric motors. Based on the conducted research, it can be concluded that the use of a simplified methodology is quite acceptable for practical application.
