摘要
针对直流电网短路故障时迅速产生的短路电流,利用IGBT器件为核心,设计出一种新型的直流短路电网限流装置并阐述了其工作原理.在分析了该装置的各种工作状态后,给出了对应的数学解析模型,为直流电网短路限流装置各参数的设计提供了理论依据.研制出小功率实验样机,并经过实验验证了解析模型的正确性和所设计的限流装置工作的快速有效性.
As the large fault current occurs in DC power system, the paper makes use of IGBT to design a new type DC fault current limiter. The FCL can limit the fault current and decrease the normal loss. The paper analyses every work state and presents the corresponding mathematic model. The theory of parameter design for DC fault current limiter is given and a small power sample FCL is manufactured. The experiment results show that the mathematic model is correct and the FCL is effective.
