| 摘 要： | 传统式距离保护方法受不同故障条件的影响,有时会产生继电器误动作。本文所提出的智能式距离保护方法综合了改进遗传算法(GA)和误差反向传播算法(BP)的优点。仿真结果表明,该方法不但比传统的距离保护方法反应更迅速、更准确,而且比目前应用较多的神经网络式距离保护有更快的网络训练速度和避免陷入局部极小点的能力,同时也满足了距离保护速度和精度的要求。

| Abstract: | Classical distance protection of transmission lines can be affected by various conditions that may sometimes lead the relay wrong reacting.The intelligent distance protection combines the advantages of the improved genetic algorithm(GA) and the error back-propagation algorithm(BP).The simulation results show that this protection not only responses more quickly and more accurately than the conventional distance protection,but also improves the training speed of the neural network.Moreover,this protection can satisy the demands of speed and accuracy for the distance protection. |
