| 摘 要： | 通过对广域保护应用基础的研究,针对广域保护对正确信息依赖的程度很高的问题,文中提出利用区域保护电网信息,将区域电网结构与改进免疫算法有机结合起来,通过算法亲和度计算和决策机制的故障选择,降低了广域保护对正确信息依赖的程度,使该区域后备保护能达到更高效,信息容错性更高,判断更准确的效应。基于此,文中选择了合适的区域保护结构,使用改进免疫算法建立了故障数学模型,并和以往算法进行了对比,通过仿真验证了模型的有效性和更高的容错性。

| Abstract: | Based on wide-area protection applied basic research, the paper puts forward using regional protection grid information to combine regional power grid structure and improved immune algorithm organically. This research has more efficient regional backup protection, higher information fault tolerance and more accurate malfunction judgment, etc. This paper chooses the appropriate regional protection structure, and use improved immune algorithm to establish the fault mathematic model, finally verify the validity of the model and high fault tolerance. |
