摘要
分析了目前直流输电工程中,控制保护系统向远方调度中心传送直流控制保护系统产生的内部故障录波信息的现状和存在的问题,研究并提出了一种直流输电控制保护内部故障录波信息采集和远传技术的新方案。该方案开发一种适应于直流输电工程换流站的故障录波前置管理机,通过磁盘映射方式快速采集直流控制保护内部故障录波信息,经调度数据网采用IEC 61850标准与调度端故障录波主站直接互联,实现直流控制保护内部故障录波信息向主站端的及时推送,从而大幅度提高内部故障录波信息采集和远传的可靠性和快速性。该方案已在实际工程中获得应用。
Firstly, the problems encountered in the remote transmission of HVDC control and protection TFR files are described and discussed. And then a new way is proposed. In the new situation, a front equipment machine is added to the HVDC control and protection system which can get TFR files from HVDC control and protection system through disk mapping and transfers information to the remote dispatch center through dispatching data network and IEC 61850. This way has been implemented in real HVDC projects.
