摘　　要：针对传统配电网继电保护定值校核方法在实际应用中校核结果与实际情况一致性系数较低,校核效果不佳的问题,提出了基于数据融合的配电网继电保护定值校核方法。首先利用D500基础平台获取保护定值数据,并进行格式统一,然后再利用数据融合技术对定值数据进行处理,采用选择性校核方式对保护定值与临界定值比较,从而实现基于数据融合的配电网继电保护定值校核。经实验表明,该方法校核结果与实际情况一致性系数较高,在配电网继电保护定值校核方面具有良好的应用前景。Due to the low consistency coefficient between the verification results and the actual situation in the actual application of the traditional distribution network relay protection fixed value verification method,and the poor verification effect,a distribution network relay protection fixed value verification method based on data fusion is proposed.First of all,the D5oo basic platform is used to obtain the protection fixed value data,the format is unified,and then the data fusion technology is used to process the fixed value,and the selective verification method is used to compare the protection value and the critical value,so as to realize the distribution network relay protection fixed value verification based on data fusion,Experiments show that the consistency coefficient between the verification results of this method and the actual situation is high,and it has a good application prospect in the fixed value verification of distribution network relay protection.
