【摘要】：特高压直流输电系统是跨区大电网互联的重要环节,承担着超过70%的跨区输送电量,高压直流输电系统运行管理水平的高低直接影响跨区电网的输电能力和生产安全。国内特高压直流输电工程运行积累时间较短,有经验的运行人员比较少,无法满足特高压直流输电快速发展的要求,迫切需要一套针对特高压直流输电运行人员的高效、全面、系统的专业化培训平台。本文基于高层体系结构的交互式实时协同仿真支撑平台,提出了交直流混联电网仿真、特高压换流站运行人员工作站(OWS)仿真、一二次设备三维场景仿真和直流控制保护系统仿真一体化的全数字化特高压直流输电仿真培训系统体系架构。本文主要研究了面向培训的特高压换流站控制保护系统仿真建模方法,在控制系统仿真方面进行了基于Hidraw控制逻辑的稳态模型仿真设计,在保护系统仿真方面提出了基于逻辑判断法的保护模型仿真设计,分别建立了特高压直流控制保护系统的控制系统仿真模型和保护系统仿真模型。在此基础上研究开发了以锦屏苏州特高压直流输电工程为原型的培训仿真系统,实现了特高压换流站运行人员工作站(OWS)、一二次设备三维场景的互动操作仿真,为直流输电生产运行人员提供了全范围、全过程、全场景的培训环境,可开展特高压换流站运行人员监盘、正常操作、设备巡检和异常及事故处理的培训,也可以用于特高压换流站运行人员的事故预演、考核以及反事故演习。目前,本系统已在现场投入运行培训工作,应用情况表明该系统为直流输电生产运行人员提供了一个效果真实、形象逼真、使用方便、培训高效的培训工具,可以在较短的培训时间里收到更好的培训效果。
[Abstract]:UHVDC transmission system is an important part of cross regional power grid interconnection, bear the cross over 70% of the transport capacity, the management level of HVDC system will directly affect the power grid transmission capacity and production safety. The domestic UHV DC transmission project operation accumulation time is short, the operating personnel experienced less. Unable to meet the rapid development of UHVDC transmission requirements, a pressing need for UHV DC transmission operation of the efficient, comprehensive, professional training system. This paper high-rise structure interactive real-time collaborative simulation platform based on the AC / DC hybrid power grid simulation of UHVDC converter station operator station (OWS) one or two equipment simulation, 3D scene simulation and full digital DC control and protection of UHVDC transmission simulation training system simulation integration The architecture of the system. This paper mainly studies the UHVDC converter station for training control and protection system simulation modeling method in control system simulation of steady-state model simulation design of Hidraw control logic based on the protection of system simulation proposed logic design model simulation method based on fault protection, the simulation model of control system and protection system the simulation model of HVDC control and protection system are established. Based on the research and development of the training simulation system prototype in Jinping Suzhou UHV DC transmission project, realized the operation of UHVDC converter station personnel workstation (OWS), the operation simulation of one or two interactive 3D scene equipment, provide a full range of staff for the operation of DC the whole production process of transmission, the whole scene of the training environment, can carry out the operation of UHVDC converter station personnel supervision, normal operation, equipment inspection Check and abnormal and accident handling training, can also be used for fault preview of UHVDC converter station operating personnel, assessment and anti accident exercises. At present, this system has been put into operation and training in the field, the application shows that the system for operating personnel of DC transmission production provides a real effect, vivid, easy to use, training efficient training tools, can receive better training results in shorter training time.
