目前,传统的直流断路器(DCCB)通常价格昂贵且缺乏限流能力。因此,本文提出了一种限流和低成本的混合式直流断路器(HCB)。当故障发生时,由于变换器模块的切断,拟议的HCB中的并联电感转换为串联连接,有效地限制了故障电流的增加。然后级联IGBT承担瞬态开断电压。能量耗散电路(EDC)基于金属氧化物压敏电阻(MOV)在能量耗散期间通过旁路限流电感来减少故障隔离时间(FIT)。因此,所提出的HCB可以限制故障电流增加的速率,降低FIT和成本。最后,通过PSCAD/EMTDC搭建的单端等值系统和直流电网测试系统验证了所提出的HCB的可行性。此外,拟议的HCB FIT比传统的ABB HCB快33.7%,能耗为87%,成本低于传统的HCB。
Nowadays, traditional DC circuit breakers (DCCBs) are always expensive and lack current-limiting capabilities. Hence, this paper proposes a current limiting and low-cost hybrid DC circuit breaker (HCB). When a fault occurs, the paralleled inductors in the proposed HCB are converted to a series connection due to the cutoff of the converter module, effectively limiting the increase of fault current. Then the cascaded IGBTs undertake the transient interruption voltage. Energy dissipation circuits (EDCs) reduce the fault isolation time (FIT) by bypassing the current-limiting inductor during energy dissipation based on the metal oxide varistors (MOVs). Therefore, the proposed HCB can limit the rate of the fault current increase, reducing the FIT and cost. Finally, the feasibility of the proposed HCB is verified by a single-ended equivalent system and DC grid test systems built in PSCAD/EMTDC. In addition, the proposed HCB FIT is 33.7% quicker, its energy consumption is 87%, and its cost is lower than that of the traditional ABB HCB.
