摘要:

针对主变冲击过程中临近发电机功率波动这一现象，首先对现场取得的录波数据进行了仔细分析。然后，在等效电路的基础上，进行了相关理论推导，揭示了冲击过程中临近发电机有功、无功的变化规律，并结合Matlab仿真工具对此现象进行了建模仿真。最后，对其主要影响因素进行了仿真验证，并提出了相应的解决措施。

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.

Key words: generator power swing excitation regulator inrush currents
