传统方法网损率较高,异常定位效果差,为此,本文设计一种新的智能配网终端就地闭环分布式测试系统。通过GUI人机界面发送智能配网终端就地闭环的测试指令,利用光电以太网接口传输至数据处理模块,实现与被测系统的连接;采用信息融合方法实现就地闭环异常定位,根据空间矢量调制矩阵变换器完成闭环控制,实现被测系统的就地闭环异常定位与控制。实验结果表明系统异常定位误差较小,智能配网的网损率得以降低,电压电流波动趋势平缓,可优化智能配网终端就地闭环测试效果。

Network loss rate of traditional methods is high, abnormal positioning effect is poor. Therefore, this paper designs a new intelligent distribution network terminal in-situ closed-loop distributed testing system. The test instruction of closed loop of intelligent distribution network terminal is sent through GUI human-machine interface, and the photoelectric Ethernet interface is transmitted to the data processing module to realize the connection with the system under test. The information fusion method is adopted to realize the closed-loop localization of the anomaly, and the closed-loop control is completed according to the space vector modulation matrix converter to realize the closed-loop localization and control of the system under test. The experimental results show that the system has small abnormal positioning error, the loss rate of intelligent distribution network can be reduced, the fluctuation trend of voltage and current is gentle, and the local closed-loop test effect of intelligent distribution network terminal can be optimized.
