The theme of the final qualification work: "Analysis of steady and transient modes in the power supply system 330/110 kV". Tasks that needed to be solved: 1. Selection of power electrical equipment: generators, transformers, selection of the section of overhead power lines, etc. 2. Analytical calculation of the steady state mode of the system and calculation of the steady state mode in the RastrWin3 software package (the mode of minimum and maximum loads, taking into account the KU) 3. Calculation of currents and voltages of a two-phase short circuit (drawing up diagrams of positive and negative sequences, using the method of symmetrical components). Construction of vector diagrams based on the results of the calculation. Calculation of an identical case in the ATPDraw âEMTPâ software package, drawing dependency graphs for a two-phase circuit, comparing the results. 4. Calculation of the dynamic stability of the system, as well as an increase in dynamic stability (taking certain measures to improve it). |
