摘　　要：为满足高速和重载列车对牵引供电系统在电能质量、电分相等问题上的需求,提出了构建基于多智能体的贯通同相供电系统的思路,探讨了系统的基本框架和实现途径与方法,设计了系统中各级Agent的结构功能,并讨论了多Agent之间的通信、协调和协作方法.设计了变电所之间的协调控制策略,以解决贯通同相供电系统中牵引变电所并网运行和变电所之间的潮流调度问题.最后,以京沪高速铁路为例进行了仿真.仿真结果表明,采用协调Agent参与分区协调的2级自治控制策略明显优于其他方式,能实现牵引变电所之间的潮流调度,并将受扰后的节点电压恢复到初始值,确保供电系统的整体电压水平.In order to solve the problems of power quality,electric section-phase insulator of the traction power supply system for electrified railway,which will affect the high-speed and heavy-load train running normally,a viewpoint on establishing an intelligent traction power supply system based on multi-agent was put forward,and the system structure and development methods were discussed.The agents＇ functions were proposed and the coordination and collaboration problems were described.To solve the problems of parallel running and power flow dispatch of traction substations,the coordination control strategy between substations was used.The numerical simulation of the proposed system for Beijing-Shanghai high-speed railway was executed.The simulation results show that the level-two autonomous control strategy with the coordination agent involved is significantly better than any other way,and it can realize power flow dispatch between traction substations,and make the disturbed node voltage recover to the initial value,so the whole voltage level of a power supply system can be ensured.
