| 中文摘要:受到多因素影响，对不同程度的异常故障信息节点，采用定量参数作为触发条件，出现部分异常故障信息感知偏差较大，造成警告保护失效的问题。为此，设计了一种基于差分天牛须算法的继电保护装置异常警告方法。计算异常警告触发的频度 无效触发概率的最大似然估计值，确定继电保护装置异常警告节点的先验概率，通过贝叶斯网络与异常警告信息节点故障树之间的相似性，对故障树进行优化，同时，引入差分天牛须算法进行二次优化，完成对应感知异常警告信息节点的位置更新，完成继电保护装置异常警告方法。实验结果表明，提出方法具备提升异常警告精准度，降低全局偏差的能力，且方法操作全过程稳定性好，扰动控制收敛适中，具有较高的研究与推广价值。 |

| An Abnormal Alarm Method of Relay Protection Device Based on Differential Beetle Antenna Algorithm |

| Abstract:Affected by multiple factors, quantitative parameters are used as triggering conditions for nodes with different degrees of abnormal fault information. As a result, there is a significant deviation in the perception of some abnormal fault information, leading to the failure of warning protection. To address this issue, a relay protection device abnormal alarm method based on the differential beetle antenna algorithm is designed. Calculate the frequency of abnormal alarm triggering maximum likelihood estimate of invalid triggering probability, determine the prior probability of abnormal warning nodes in relay protection devices, optimize the fault tree through the similarity between Bayesian network and abnormal warning information node fault tree, and introduce the differential beetle algorithm for secondary optimization to complete the position update of corresponding perceptual abnormal warning information nodes, complete the abnormal alarm method for relay protection devices. The experimental results show that the proposed method has the ability to improve the accuracy of anomaly warnings, reduce global deviations, and has good stability throughout the operation process. The disturbance control convergence is moderate, and it has high research and promotion value. |
