以固态开关为主要元件的换流器实时仿真是实现VSC-HVDC 实时仿真的难点之一。目前电磁暂态仿真程序的理想开关模型因为计算效率的问题很难实现实时仿真。所以电感/电容(L/C)模型由于较高的计算效率而在实时仿真中被考虑采用。该文深入研究使用L/C模型的开关的准确性，证明了小步长算法的可行性。同时，考虑模型暂态误差产生的损耗，提出了完整的小步长模型的参数设置方法。所提出的模型建立在ADPSS上，并与PSACD上的理想模型进行了比较，验证了模型的准确性。

The real-time simulation for solid switch converter is one special difficulty in the field of simulation of VSC-HVDC transmission systems. The current ideal switch modeling in electromagnetic simulation can not realize real-time in small time step. Therefore the L/C equivalent modeling was applied to improve computation efficiency and the accuracy of the modeling and the feasibility of small time step algorithm were verified theoretically. Furthermore, the optimization of parameters of this model were also discussed. Finally, an advanced L/C model for switches was established. This novel model was implemented in ADPSS and verified by the simulation in PACAD.
