摘要
针对两机系统,提出了在输电线路不同位置发生三相短路故障时,超导故障限流器(SFCL)投入电抗后对暂态稳定性影响的分析方法。基于功角特性曲线分别详细分析了在三相短路故障下电抗型SFCL对暂态稳定的影响情况。通过对接入电抗型SFCL的电力系统进行故障下的暂态稳定时域仿真研究,验证了分析结论。
Transient stability of two machine systems with Superconducting fault current limiter（SFCL） is analyzed under three-phase circuits.The SFCL is considered to introduce a reactance into the three-phase circuits when faults occur.Based on the power-angle curves for three-phase circuits,the influences of the Reactance-Type SFCL to transient stability is analyzed in details.The time-domain simulation of transient stability is carried out to verify the analytical results.
