| Power distribution network is an important component in power system which directly distributes power energy to the users. It's operational stability and reliability seriously influences the user's production and life. With the social development and improvement in people's living standard, people makes greater demands on energy quality and reliability. It's very urgent to realize distribution feeder automation for the sake of higher operational and managing level in distribution network.This thesis makes a systematic reaserch and analysis about distribution network, compares some schemes about realizing feeder automation system and discusses the universal layered and distributed feeder automation sheme which based on feeder terminal unit(FTU) in detail.Combined with the practical situiation in distribution network, it's suitable to select graph algorithm as the theoretical algorithm base. Based on structure variable dissipated network theory, this thesis detailedly discusses the transforms of base-to-shape, shape-to-base, vertex-to-arc, arc-to-vertex, over-heated arc dectection, load allotting, load balancing and optimum restoration. The author developes this theory and brings forward a new method to solve feeder automation algorithm for processing special distribution network connection.This thesis studies the architecture of feeder automation management program further, and analyses the graphics configuration module, the database module and the algorithm module. The communication module and report module are also discussed. Based on these, the author makes use of Visual C++ 6.0 and SQL Server 2000 to develop an open management program. It is proved to be reliable, flexible and practical in practical use. |
