重合闸在配电网自动化中的应用探索
|
Abstract:
通过将重合闸应用到配电网自动化中,提出了一种新型的智能电网技术。该技术能够在配电网中快速定位故障,快速切除故障点,并配合开关遥控功能,远方进行开关分操作,实现非故障段快速转供电,进一步缩短用户的停电时间。通过PSCAD/EMTDC仿真实验,证明新方案充分利用了重合闸和配电网自动化的特点来保证继电保护的选择性和快速性。
A new type of smart grid technology is proposed by applying reclosing to distribution network automation. The technology can quickly locate faults in the distribution network, quickly remove the fault point, and cooperate with the switch remote control function to perform switch operation in the distance to realize fast power supply to the non-fault segment, further shortening the power outage time of the user. Through PSCAD/EMTDC simulation experiments, it is proved that the new scheme makes full use of the characteristics of reclosing and distribution network automation to ensure the selectivity and rapidity of relay protection.
