摘　　要：对多端柔性直流输电控制保护系统的三层分布式结构进行阐述,针对多端协调控制功能,提出直流控制系统设计为三层结构,分别为:站间协调控制层、极控制层和换流器控制层,其中在站间协调控制层采用多端主控制器来实现各换流站控制器间的协调,保证直流多端电网失去直流电压控制站后,继续维持直流电网电压在额定值附近。对多端柔性直流输电控制保护系统中组网方式进行归纳总结基础上,提出基于站间快速通讯的多站协调控制和基于上层控制的多站协调控制,这种方式对于多端柔性直流输电系统站间协调控制是有效的。The three-level hierarchical design of multi-terminal VSC HVDC transmission control and the protection system are presen-ted in this paper,focus on coordinated control function of multi-terminal VSC HVDC,a kind of three-system including coordinated control level,pol a control level,and converter control level is designed in this paper,coordinated control function is implemented in multi-terminal master control macliine,which ensure the rated DC voltage of networkDC voltage control station of multi-terminal VSC-HVDC,communication network stle among diferent converter stations in of multi-terminal VSC-HVDC,communication network stle among diferent converter stations in multi-terminal VSC-HVDC is presented, based on the communication networ style,a knd of coordinated control base on converer to converer high speed communication as well as top level control for thie multi-terminal VSC HVDC system is demonstrated in this paper,and this trol frame for multi-terminal VSC HVDC.
