分散式智慧型代理人應用於船舶配電系統復電轉供

Distributed Intelligent Agents for Service Restoration in Ship Electrical Distribution Systems

船船電力系統在遭受外力使船體受損或因內部設備故障而中斷供電時，如何快速復電轉供為未來船電系統重要發展方向之一，為有效提昇船舶電力系統供電可靠度，本文運用智慧型多代理人系統（Multi-Agent System，MAS）概念，建立船舶配電復電策略，執行故障之隔離與復電轉供。當故障點被偵測與隔離後，運用MAS內的電力電子模組代理人推導適當的復電計畫，並依據船舶配電系統復電標準作業流程，執行復電轉供，縮短停電時間。為估算MAS之資料傳輸延遲，並驗證本文所提方法之執行效能，離散事件模擬技術（discrete event simulation technique）被使用來模擬幾種常見的船舶配電故障狀況之復電轉供程序。模擬結果顯示，相較於傳統集中式控制，MAS可在較短時間內完成系統復電轉供，將有助於系統供電可靠度的提昇。 Service restoration during a limit in ship electric power systems due to external forces or internal faults is an important task for future ship power systems design. To enhance the system reliability, a multi-agent system (MAS) concept is utilized in this paper to build an effective service restoration strategy for performing fault isolation and restoration by feeder reconfigurations. When a fault in the system is detected and isolated, an appropriate restoration plan is derived by power electronic building blocks (PEBBs) used in the MAS to determine and perform the restoration plan according to the system emergency operation procedure. To evaluate the data transfer delays of the MAS and ensure the performance of the proposed method, a discrete event simulation technique is used to simulate the service restoration procedures for several common fault conditions in ship electrical distribution systems. Simulation results have shown that with the MAS, the restoration procedure can be done in a shorter time than the concentrated control and therefore, system reliability is greatly enhanced.
