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-H VDC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-H VDC 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。

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.
