摘　　要：为了研究现有计量器具对柔性直流输电系统能效计量的适应性,文中利用RTDS系统,建立了基于模块化多电平换流器(MMC)的双端柔性直流输电实时数字仿真系统,在此基础上进行柔性直流输电系统的谐波分析和能耗分析。将不同型号电表按规定接线方式与RTDS仿真系统连接,研究不同类型的电表在柔性直流输电系统计量中的适应性。仿真和实验结果比较说明:柔性直流输电系统中主要的能耗来源为联结变压器和换流器,且现有的计量装置适用于该系统。In order to study the adaptability of existing measuring instruments to the energy metering of flexible HVDC system, a real-time digital simulation system based on modular multi-level converter （MMC） is developed based on RTDS system. The harmonic analysis and energy consumption analysis of the HVDC transmission system are carried out. Different types of meters are connected to the RTDS simulation system according to the specified wiring mode to study the adaptability of meters in the measurement of flexible HVDC transmission system. The main sources of energy consumption in flexible HVDC systems are connection transformers and converters, and existing metering devices are suitable for this system.
