摘要
通过研究交流侵入直流系统的方式,设计了一套主动式交流窜入保护装置,并对该装置的功能结构和硬件结构进行分析。试验和运行结果表明,该装置实现了迫跳交流窜入故障,可确保发电厂直流系统处于良好的运行状态。
This paper studies the way of AC intrusion into DC system,designs a set of active AC intrusion protection device,and analyzes its functional and hardware structure.The test and operation results show that the device realizes the forced trip of AC intrusion fault and ensures that the DC system of power plant is in a good running state.
