基于电力物联网缩短欧变停电抢修时间的技术研发及应用

Technology development and application to shorten the time for emergency repairs of European transformers based on power internet of things

缩短配网故障抢修时间、提升供电可靠性已成为上海地区电力发展的一项重要任务。本文针对欧变自身特点进行分析,阐述了欧变低压开关跳闸后导致的停电抢修时间较长的现状。为积极响应国网公司电力物联网建设的要求,在感知层使用新型、可带电安装的传感器,从而提出缩短欧变低压开关跳闸的停电抢修时间的有效措施,提升了配网的可靠性。在市南供电公司辖区内推广,取得的经济效益验证了其可行性,为建设一流城市智能配电网提供了实践方案。

Shortening the repair time of distribution network faults and improving power supply reliability have become an important task in the development of power in Shanghai in recent years.This paper analyzes the characteristics of the European transformers,and expounds the current situation of long power failure repair time caused by the low voltage breakers’tripping.Actively responding to the requirements of the state grid corporation's ubiquitous power internet of things construction,using the newest and electrically installable sensors in the sensing layer,thus proposing effective measures to shorten the blackout and repair time of the European transformers’low-voltage switch trip,and improve the reliability of the distribution network.Promoted in the jurisdiction of the Shanghai Shinan power supply company,the economic benefits obtained verify the feasibility,and provide practical solutions for the construction of first-class urban smart distribution network.
