中文摘要：

相比传统高压直流输电,模块化多电平换流器型高压直流输电（MMC-HVDC）的一次系统与二次系统都更为复杂,并且控制器的特性一定程度上决定了MMC-HVDC系统的性能。使用快速控制原型技术可以加快MMC-HVDC系统的控制器开发。基于面向仪器系统的PCI扩展（PXI）开发了MMC-HVDC系统的快速控制原型。首先,在PXI环境中设计了MMC-HVDC系统的控制策略,开发调试了控制程序,配置了输入/输出板卡及端口,实现了快速控制原型。其次,建立了基于实时数字仿真器（RTDS）的MMC-HVDC一次系统模型。最后,建立了RTDS-PXI混合实时仿真系统。混合实时仿真实验结果表明,所设计的快速控制原型可以进行MMC-HVDC系统启动、子模块电容电压均衡、母线电压和有功功率调节等控制,具有优良的稳态与暂态性能。

英文摘要：

Compared with high voltage direct current（HVDC）transmission,the primary system and secondary system of modular multilevel converter based high voltage direct current（MMC-HVDC）are both more complicated,and to a certain extent the characteristics of the controllers determine the properties of the MMC-HVDC system.Using the rapid control prototype（RCP）can accelerate the development of the MMC-HVDC controller;based on the PCI extension for instrumentation（PXI）,the rapid control prototype for MMC-HVDC system is developed.First,based on the PXI device,the control strategy for the MMC-HVDC system is designed,the control program is developed and debugged,the input/output boards and ports are configured,and the rapid control prototype for MMC-HVDC is built.Second,the MMC-HVDC primary system model based on the real-time digital simulator（RTDS）is developed.Finally,the RTDS-PXI hybrid real-time simulation system is formed.The experimental results of hybrid real-time simulation show that the designed rapid control prototype of MMC-HVDC system has the ability to start the MMC-HVDC system,balance the capacitor voltage of the sub-modules, control the bus voltage and active power in addition to desirable steady-and transient-state performance.
