Fault Restoration For Distribution Network Base On Dissipated Network

As a result of the development of power systems,system has great application background and tremendous the distribution automation marketable value. The fault section system, location and the reconfiguration are key functions of the distribution automation so they are become of the research direction for a lot of people in the world.Whatever algorithms assumed, the fault section location and reconstruction are not independent of the topology model of distribution networks and a good topology model will help to realize these functions. To increase the reliability, it should be in time to ensure the fault section when there is a fault appeared. On the base of analysis of traditional models and features for distribution networks, this paper presents a new model——structure variable dissipated network. We put forward distribution information a fault networks section location fast algorithm from the practicability of the fault section location, which first makes use of some vertexes to ensure the zone of the fault then makes use of the vertexes of this zone to locate the fault section exactly. This algorithm has simplified the computation greatly and improved the real-time character of fault section location algorithm, which ensures he engineering practicality of fault section location algorithm.Reconfiguration of distribution networks, which is a key function of distribution automation system, is an important guarantee to enhance reliability of power supply and flexibility of power operating condition. Analyze the service restoration in detail .With respect to different conditions of service restoration, design different objectives and use different restoration methods.
