Abstract: Rapid restoration system has been lack of adequate technical support to low voltage fault location ever since. This paper design and realize a fault location technology analysis and rapid restoration system, basing on data which provided by grid model of information integration platform and fault information from distribution network automation system, and variable terminal real-time information. According to the user alarm information, fault information and terminal data, this system can automatically find out low-voltage fault location, offer technical support to customer service first-hand blackout range information, also support effective guide to salvage crews restoring electricity. Research results set an example and apply in Zhongshan power supply bureau, and the effect is good.
