Abstract: |
In view of the phenomenon of the nearby generator power swing in transformer magnetizing, the site wave recording data is studied in detail firstly. Then based on the equivalent circuit and through correlative theory deduction, the variation rule of the nearby generator’s active power and reactive power in the impact process is revealed and the phenomenon is simulated by using MATLAB. At last, the main influence factors are proved by simulation and correlated measures to solve the problem are proposed. |
