摘要(Abstract)：

随着电力系统设备规模和供电规模的不断扩大,互联程度也越来越高,由此导致电网的短路阻抗减小而短路电流水平急剧增大。不断增大的短路电流会对设备本身及其通信线路造成不同程度的危害,甚至影响到整个系统的安全稳定运行。为此,提出了一种混合型短路电流限制器,分析了其基本工作原理并推导了数学模型,并进行了模型设计,通过仿真验证了该设计的可行性。
With the expansion of power system devices and power supply scale, the power systems are more interconnected, resulting in short circuit impendence decrease and the short circuit current rise. The increased fault current brings varying degrees of damage to devices and communication lines, or even influences the operation safety and stability of the whole system. Therefore, this paper proposes a hybrid short-circuit current limiter, and analyzes its basic operation principle and deduces a mathematical model. After that,it conducts a model design and through a simulation validates the feasibility of the design.
