基于光纤通信的10 kV联络线备自投装置应用

目前备用电源投入装置主要用于110 kV及以下变电站的进线、母线、变压器等设备的备用自投。随着用户对用电质量要求越来越高，面向用户的10 kV联络线也需要安装备自投装置。为此，合作研发了基于光纤通信的联络线备自投装置，验证了该装置能够实现2条10 kV联络线的相互备用、快速投切功能。该装置的投入使用，提高了电网供电的可靠性，同时取得了显著的社会与经济效益。

Application of Spare Power Automatic Switching Device for 10 kV Tieline Based on Optical Fiber Communication

Spare power automatic switching device is mainly used for the incoming line , bus and transformer in substations of 110 kV and below. With the increasingly higher requirements of users on power quality , the user-oriented 10 kV tieline also needs spare power automatic switching device. Thus , spare power automatic switching device for tieline based on optical fiber communication is developed through cooperation. It is veri-fied that the equipment can realize mutual backup and quick switching between two 10 kV tielines. The uti-lization of this equipment improves the reliability of grid power supply and in the meantime achieves signifi-cant social and economical benefit.
