| 中文摘要: |
| 无功补偿的电容器，应有一定的容量限制，原则是不与电机励磁曲线在线性段相及右侧相交，避免产生自激电压。本文通过对异步电机运行状态、就地并联装置与异步发电机电路、自激过电压形成过程的分析，得出对无功补偿容量限制的必要性，以及在必须超出限制容量时，避免产生自激过电压的措施。 |
| 英文摘要: |
| The capacitor of reactive compensation should have a capacity limit, and the principle is that the excitation curve of the motor should not connect with the linear section and the right side to avoid self-excited voltage. In this paper, through the analysis of the formation process of the asynchronous motor running state, local parallel device and asynchronous generator circuit and self excitation overvoltage formation, the necessity of reactive power compensation capacity limit and the measures avoiding self over-voltage when must beyond the capacity limit is put forward. |
