| 摘 要： | 随着分布式电源的引入,传统的配电网保护系统难以满足运行方式灵活多变的多DG配电系统的要求.为此,基于最大故障特征信息量准则提出了一种适用于含DG配电网的保护算法.该算法以广域保护原理为基础,以通信为支撑,仅利用电流量进行故障搜索方向的判别,适用于无PT通道的中低压配电网.算法分故障区域定位和故障区段定位两步完成.故障区...

| Abstract: | With the introduction of distributed generation(DG),the traditional distribution network relaying protection is difficult to meet the requirements of flexible distribution systems.A new algorithm based on maximum fault characteristic information criterion for distribution network including DG was proposed in the paper.With wide area protection principle and communication system,the proposed algorithm uses currents to identify fault searching direction and it is suitable for low-voltage distribution network ... |
