    摘要:

    基于传统半桥子模块(half bridge sub?module,HBSM)的模块化多电平换流器(modular multilevel converter,MMC)无法阻断直流侧短路故障电流,该故障电流降低了MMC高压直流输电系统(MMC based high voltage direct current, MMC?HVDC)的可靠性。以2个HBSM为基本结构,研究设计一种能够有效阻断直流故障电流的新型旁路型子模块,即二极管钳位型双半桥子模块(diode clamp dual half bridge sub?module,DCDHBSM)。相较于具备直流短路电流阻断能力的其他子模块,所提DCDHBSM所需功率器件较少,运行损耗较低。此外,还设计适用于DCDHBSM的直流故障穿越策略,利用排序算法均衡了故障后的子模块电容电压。MATLAB/Simulink和物理仿真试验结果均证明了装配所提DCDHBSM的MMC在快速阻断直流故障电流及实现故障穿越等方面的有效性。

    Abstract:

    The DC short-circuit fault current cannot be blocked by the modular multilevel converter (MMC) with traditional half-bridge sub-module (HBSM), which reduces the reliability of MMC based high voltage direct current (MMC-HVDC) systems. In this paper, based on two HBSM systems, a new bypass sub-module named diode clamp dual-half-bridge sub-module (DCDHBSM) with DC fault current blocking capability is proposed. Compared with other sub-modules possessing DC short-circuit current blocking capability, the proposed DCDHBSM requires fewer power devices and has lower operation loss. Moreover, a DC fault ride-through strategy suitable for DCDHBSM is designed, and sorting algorithm is utilized to balance the post-fault capacitor voltages of the sub?module. The results of simulation based on MATLAB/Simulink and physical experiment show that MMC assembled with the proposed DCDHBSM can quickly block DC fault current and realize fault ride-through.
