摘　　要：为准确分析特高压直流输电控制保护系统稳态运行与暂态过程的真实响应,在深入研究其分层控制机制和各控制环节原理的基础上,基于PSCAD/EMTDC平台建立实际控制保护系统的电磁暂态仿真模型,采用分时触发并行计算的方法完成各个子任务程序的同步计算,并对特殊功能模块、触发脉冲控制等关键环节进行程序设计。通过对模型进行大量的仿真测试并与实际录波对比,验证了仿真结果与实际动态响应的一致性。仿真模型已应用于锦屏—苏南特高压工程系统调试的分析计算中,也能为已投运及规划中的多条特高压直流的科学研究和工程计算提供重要技术支持。To analyze true responses of control and protection system during steady-state operation and transient process of UHVDC transmission project accurately, on the basis of detailed research on the hierarchical control mechanism and principle of each controlling unit, based on the platform of PSCAD/EMTDC an electromagnetic transient model of the actual control and protection system is built. The synchronized calculations of all subtasks are performed by time-sharing trigger and parallel computing, and the programs for key units such as specific functional modules and firing pulse control are designed. Through a lot of simulation and tests for the built model and comparing with actual recorded waveforms, the consistency between simulation results and dynamic response of actual control and protection system is verified. The built simulation model has been applied to the analysis and calculation in the commissioning of UHVDC transmission project from Jinping to Sunan. The built model can also offer technical support to the research and engineering calculation of multi UHVDC transmission projects being put into operation and being planned.
