为实现配电网中电能质量扰动源的自动定位,首先提出了一种基于配电线载波通信(DLC)的网络化电能质量监测系统解决方案,并概括了扰动源自动定位方法的总体实施步骤.分别采用有功电流分量法和基于特征矩阵运算的算法实现单监测点扰动方向的判定和扰动源的自动定位.最后,总结了DLC组网方案的四个关键技术,包括信道特性、调制技术、路由策略和监测终端设计.研究表明,所提方法可以有效实现辐射型配电网中电能质量扰动源的自动定位,DLC组网方案具有显著的经济性.
Aiming at locating power quality disturbance source in distribution network automatically, a solution scheme was proposed based on networked monitoring system with distribution line carrier (DLC) communication. The overall implementation steps for disturbance source automatic locating are introduced in summary. The disturbance direction of single monitoring point was determined by active current component method and automatic locating of disturbance source was realized with the algorithm based on characteristic matrices operation. Finally, the four key technologies of networking program with DLC technique were summarized, such as characteristics of DLC channels, modulation technique, routing strategies and design of monitoring terminal. The research shows that the proposed methods can locate disturbance source automatically in radial distribution networks. The DLC networking program has significant economic benefits.
