摘要
基于RT-LAB实时仿真平台,研究了实时仿真技术在基于模块化多电平换流器(MMC)的柔性直流输电系统(HVDC)中的应用。建立了基于MMC的柔性直流输电系统的实时仿真模型,并将RT-LAB的实时仿真结果与PSCAD/EMTDC的离线仿真结果进行了对比验证。两种仿真结果在暂态和稳态下都比较一致,这说明通过RT-LAB可以得到MMC高压直流输电系统的正确仿真结果。还对两种仿真方法的仿真时间进行了对比,说明通过RT-LAB的实时仿真可以大幅度提高对MMC换流器的仿真效率。研究结果为采用RT-LAB平台对柔性直流输电系统等大规模电力电子装置实时仿真研究应用提供了参考。
The real-time simulation tool, RT-LAB, is applied to simulation of modular multilevel converter（MMC） based VSC-HVDC power transmission system. A real-time simulation model of MMC based HVDC power transmission system is built with RT-LAB. The simulation results from RT-LAB are compared with the results from PSCAD/EMTDC, and the comparison shows that the waveforms obtained by the two simulation tools are coincident in both dynamic state and steady state, which verifies the validity of the RT-LAB simulation for MMC based HVDC power transmission system. The simulation time of RT-LAB and PSCAD/EMTDC is compared, indicating RT-LAB is far more efficient since it performs a real-time simulation.
