Abstract

In this paper, a new algebraic-graph method for identification of islanding in power system grids is proposed. The proposed method identifies all the possible cases of islanding, due to the loss of a equipment, by means of a factorization of the bus-branch incidence matrix. The main features of this new method include: (i) simple implementation, (ii) high speed, (iii) real-time adaptability, (iv) identification of all islanding cases and (v) identification of the buses that compose each island in case of island formation. The method was successfully tested on large-scale systems such as the reduced south Brazilian system (45 buses/72 branches) and the south-southeast Brazilian system (810 buses/1340 branches).

电力系统电网孤岛识别的代数图法

本文提出了一种新的电力系统电网孤岛识别代数图方法。该方法通过对母线-支路关联矩阵的分解，识别出由于设备丢失而导致的所有可能的孤岛情况。这种新方法的主要特点包括:(i)实现简单，(ii)速度快，(iii)实时适应性强，(iv)识别所有孤岛情况，(v)识别组成每个岛屿的公共汽车。该方法在巴西南部系统(45辆公交车/72个支路)和巴西东南部系统(810辆公交车/1340个支路)等大型系统上进行了成功的测试。
