碩士 === 國立高雄應用科技大學 === 電機工程系 === 97 === Distribution automation and customer automation have already been important development trend of power that obviously will enhance power service quality. A multiagent system is developed to enhance restoration quickly for fault contingencies on distribution systems with JADE in this thesis. The multiagent system (MAS) integrates the information of topology processor and loadings characteristics of service zones, distribution feeders and main transformers in substations to derive the proper restoration plan after the faulted location has been identified and isolated. The heuristic rules based on standard operation procedures of Taipower’s distribution system an included in the heat first search of the MAS to ensure the restoration plan derived will comply with the operation regulation. When the capacity reserves of supporting feeders and main transformers are not enough to cover the fault restoration for fault contingency, the load shedding is determined by the MAS to restore service to as many key customers as possible by considering the service priority of each service zone of distribution feeders. Besides, the thesis also considers the impact on the operation, planning and maintenance of distribution systems with distributed generation. The intention islanding for the feeder was analyzed after the execution of switching operation and load shedding procedure. Finally, it needs to analyze its stability by using Matlab/Simulink. A Taipower distribution system with 35 feeders is selected for computer simulation to demonstrate the effectiveness of the proposed methodology to solve the service restoration plan for distribution fault contingency by applying MAS.
