摘要: 从理论和应用相结合的观点剖析了分层式电网区域保护的实现方法,提出了基于多Agent单元的协同保护方法。对各测量点Agent单元的故障信息进行卡尔曼滤波优化融合,得到故障方向信息,形成故障关联矩阵,根据关联矩阵和判据实现故障判断。理论分析和大量仿真表明:该方法可以有效地定位故障元件。该区域保护可与传统的“点保护”相配合,能有效地解决供电系统中“越级跳闸”的问题。

Abstract: A multi-agent units-based coordinated protection method is proposed based on analyzing the methods for realizing hierarchical regional protection of power system. The fault information of each measurement point’s agent unit is firstly optimized by Kalman filter, and then the fault direction information and the fault correlation matrix can be obtained. Finally, the fault location can be determined according to the correlation matrix and the criterion. Numerous theoretical analysis and simulation results show that such method can effectively locate the fault components. This regional protective system can match with the traditional point protection and solve the override trip problem in the power supply system.

Key words: regional protection system, multi-agent units, Kalman filtering, fault correlation matrix, override trip
