±800 kV特高压直流输电工程实际控制保护系统仿真建模方法与应用
A Modeling Method for Actual Control and Protection System of ±800kV UHVDC Transmission Project and Its Application
摘要
Abstract
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.关键词
