摘要
未来15年内,中国电网将是一个具有20多回超/特高压直流输电系统的交直流并列运行的特大型特高压电网,大电网的建模、仿真及分析技术遇到了严重挑战。该文讨论大电网特高压直流系统仿真建模技术的最新进展及研究方向,并介绍中国电力科学研究院系统所正在开展的电磁暂态/机电暂态混合仿真技术研究工作及直流控制系统详细建模工作,将其应用于工程实际后,将对中国电网未来的规划、运行及科研工作中的大电网特高压交直流系统仿真分析带来巨大突破。
Chinese power grid will be a super-huge, AC/DC parallel operation, high-voltage grid with more than 20 UHVDC systems. The modeling and simulation technologies for large power system will face serious challenges. The new development of this aspect for large power systems with ultra-high voltage AC/DC operation is discussed. The electromagnetic transient/electromchanical transient hybrid simulation technologies developed by Power System Department of CEPRI are introduced, as well as the detailed DC control system models. These will bring great breakthrough for the simulation of Chinese future large power grid with ultra-high voltage AC/DC systems.
