基于智能开关的广州10kV架空馈线自动化新模式

根据广州地区10 kV架空线路的实际情况,提出两种基于柱上智能开关的广州地区10 kV架空馈线自动化新模式,应用了柱上智能开关、线路设备保护、智能控制器和PLC控制器,可实现二遥监测、减少变电站出线开关跳闸、缩小停电范围、自动隔离故障、迅速恢复非故障区域的正常供电等功能。分阶段在广州不同地区对馈线自动化新模式进行试点,结果表明架空线路馈线自动化新模式适合广州实际,在广东地区具有广阔的应用前景。

Discussion on Automatic New Model for Guangzhou 10kV Over Head Feeder Line Based on Intelligent Switch

Based on the actual situation of 10 kV overhead line in Guangzhou,the new automation mode for 10 kV overhead feeder in Guangzhou based on two kinds of pole-mounted smart switches is proposed.It uses the pole-mounted smart switch,line equipment protection,intelligent controller and PLC controller,which can realize the functions such as the secondary remote monitoring,decreasing the tripping times of outlet switch in substation,reducing the range of power interruption,isolating the fault automatically,recovering the normal power supply for the non-trouble area quickly etc.The pilot for the new automation mode of feeders is carried out in different areas of Guangzhou by stages.The results show that the new automation mode for 10 kV overhead feeder is suitable for the actual situation of Guangzhou,which will have a wide application in Guangdong area.
