摘　　要：针对现有的低压配电网络线损诊断技术主要利用用电数据,在检测精度和检测范围方面存在局限性的问题,文中基于对配电网络的复阻抗等电路网络参数的测量,提出一种面向低压配电网络线损智能诊断系统,并对系统架构、硬件电路和基于支持向量机集成诊断算法进行设计和实现。实验仿真结果表明,文中所提出的智能诊断系统可以增强线损分析的准确性,能够有效判别区域内的窃电线损和其他线损。文中所提方案是现有线损管理系统的有效补充,能够提高现有的低压配电台区的线损管理水平。As the existing line loss diagnosis technology for low⁃voltage distribution network mainly uses power consumption data,which has limitations in the detection accuracy and detection range,a line loss intelligent diagnosis system for the low⁃voltage distribution network is proposed based on the measurement of circuit network parameters such as complex impedance of distribution network,and the system architecture,hardware circuit and integrated diagnosis algorithm based on support vector machine are designed and implemented.The experimental simulation results show that the intelligent diagnosis system proposed in this paper can enhance the accuracy of line loss analysis and effectively distinguish the stolen line loss and other line losses in the region.The proposed scheme is an effective supplement to the existing line loss management system and can improve the line loss management level of the existing low⁃voltage distribution station area.
