摘要
提出了将无线传感器网络(wireless sensor network,WSN)应用于分布式母线保护的新理念,并针对无线传感器网络的特点,提出了采用比较行波方向作为分布式母线保护的故障判别原理,对于单母线、双母线运行方式分别设计了无线传感器网络的拓扑结构以及数据融合的处理算法,以具体的母线保护为例,评估了无线传感器网络的性能,并就实用化过程中数据传输的可靠性以及与现有电力网络的互联进行了探讨。通过仿真分析证明了无线传感器网络能够满足分布式母线保护的要求。
In this paper, the idea of wireless sensor network(WSN) for DBP is proposed. According to the features of WSN, the DBP principle based on current traveling waves is presented, and the topology structure and data fusion of WSN are presented in accordance with different busbar operation modes. As a concrete example to busbar protection, the performance of WSN is evaluated. The reliability of data delivery and interconnection with existing power communication network is discussed. The simulation has proved that WSN can satisfy the requirement of DBP.
