| 中文摘要 | 针对自励异步发电机自身存在的带负载能力差的缺点,采用并联补偿电容的方法来解决这一问题。以独立运行异步发电机等值电路为基础,令电路的回路阻抗为零,采用降阶消元的简化迭代方法分析异步发电机的稳态运行性能,计算结果与实验结果相吻合,说明了分析方法的正确性。通过比较自励异步发电机带电阻性负载和阻抗性负载时投入不同数值的并联补偿电容后的外特性说明了并联补偿电容能够提高异步发电机的带负载能力。计算还表明,投入并联补偿电容的时机不同会影响异步发电机的电压调整率,通过比较投入前后的最大电压调整率得到了电容的最佳投入时机。; To improve the inherent external characteristics of a self-excited induction generator (SEIG), shunt compensation capacitors connected to the stator terminal are utilized. On the basis of equivalent circuit of induction generator in independent operation and let its loop impedance be equal to zero, the steady state operation performance of the induction generator is analyzed by deflation and elimination based simplified iteration method, the fact that the calculation results coincide well with experimental results show that this analysis method is correct. The comparison results of the external characteristics of the self-excited induction generator with resistive load and inductive load, when different capacity of shunt compensation capacitors are connected to the induction generator, show that the load-carrying capacity of induction generator can be improved by shunt compensation capacitors. The calculation results also show that the voltage regulation factor will be influenced by different opportunity while the shunt compensation capacitors are put into operation. Comparing the maximal voltage regulation factors before connecting capacitors and after that the best opportunity of putting the compensation capacitors into operation is obtained. |
