摘要 主要对新型高温超导限流器位于机端时对单机无穷大系统中暂态稳定性的影响进行了分析,并结合实验室新型超导限流器样机进行动态模拟试验研究。研究表明,超导限流器位于机端时,由于限流电阻的存在,不仅能有效限制故障电流,而且有利于系统的暂态稳定性。理论分析与试验结果基本一致。 A new type superconducting fault current limiter was developed by Institute of Electrical Engineering, Chinese Academy of Sciences. This paper analyses the power system transient stability in a single machine with infinite bus system by using the fault current limiter. A simplified model of the fault current limiter is also given during the simulation. Experimental study is on a 600 V/ 50 lab prototype at EPRI. Results from the theoretical analysis and experiments show that superconducting fault current limiter can not only limit the fault current, but also can enhance the transient stability of the power system with a suitable parameter design. Simulation results well agree with the experimental results. The future application of superconducting fault current limiter will not remain within the domain of distribution system, but will be extended to the transmission power system.
