【Abstract】 A Windows NT based distribution management system called TH--DMS is developed. The software is coded withC++ language and ODBC. Commercial database, such as MS SoL Server, combined with a self--developed real--time databaseis implemented. The application functions include topological analysis, distribution transformer load forecasting, stateestimation, load flow calculation, network reconfiguration, optimal capacitor switching, short circuit current calculation.fault isolation and service restoration, dispatcher training, customer’s application processing. facility management, Webbased remote data browser, etc. Most of the algorithms adopted in the TH-DMS, such as branch estimation-based stateestimation. two--portion load flow calculation for single loop type network, recursive fictitious flow algorithm for networkreconfiguration, successive linear integer programming algorithm for optimal capacitor switching, etc. have the features ofrapid calculation and good adaptability and can satisfy the practical requirements of distribution systems in China. Some ofthese algorithms. i. e. topological analysis, load forecasting. state estimation and load flow calculation. have beenimplemented in Shaoxing Distribution System in Zhejiang Province.更多还原
