摘要
为了在多回路模型配电系统上获得继电器保护定值,提出了使用Firefly算法(FA)来优化计算继电器保护定值,通过继电器的良好、快速整定,外部干扰引起的衰减问题可以被抑制到最小,还可以缩短人工计算时间,快速得到整定值,并将整定值最优化。通过使用ETAP软件进行验证,结果表明,使用FA从优化结果中获得继电器整定值,14个继电器的总运行时间为3.717 s,与手动计算的4.339 s相比,快了0.622 s。
In order to obtain the relay protection setting value on the multi loop model distribution system,a fire optimization algorithm is proposed to calculate the relay protection setting value.Through the good and fast setting of the relay,the attenuation problem caused by external interference can be minimized,the manual calculation time can be shortened,the setting value can be obtained quickly,and the setting value can be optimized.Through the verification by ETAP software,the results show that the relay setting value is obtained from the optimization results by using the Firefly algorithm.The total operation time of 14 relays is 3.717 seconds,which is 0.622 seconds faster than the 4.339 seconds calculated manually.
