基于正序故障分量方向比较原理的广域继电保护算法

对广域方向纵联保护算法进行深入研究，得到一种广域继电保护算法，该算法的原理是对正序故障方向进行比较：利用智能电子设备IED （Intelligent Electric Device，IED）的定位，将线路、母线组成IED关联域。在这个系统出现故障时，通过IED在关联域内对故障信息的采集和共享，结合文中定义的故障判别原则，可以得出发生故障的位置。通过IED设定的相应策略，快速排除故障。

A Wide-area Relaying Protection Algorithm Based on Positive Sequence Power Direction Comparison Principle

To deeply research direction longitudinal wide-area protection algorithm,get a wide-area relay protection al-gorithm, the principle of the algorithm is of positive sequence fault direction, use of intelligent electronic devices posi-tioning,will line,busbar IED correlation domain. In the system failure,through the IED in correlation domain of fail-ure information collection and sharing, combined with the definition of fault principle, you can find the fault location. By setting up corresponding strategy of IED,quick troubleshooting.
