摘要
分析了快速限流器对配网短路电流、电压质量和分布式电源的影响。结果表明,快速限流器可降低配网短路电流,提高分布式电源的动态稳定性;但在变压器并联时,若配网发生短路故障,该设备对10 kV母线电压跌落的影响取决于故障点位置。
This paper studies the impacts of Is-limiter on the operation of distribution system in terms of short circuit current level,voltage quality and DG dynamic performances.The results shows that the Is-limiter can reduce the short circuit current and improve the stability of the DG.Moreover,once short circuit occurs on the distribution side,the voltage sags of the buses are depended on position of the fault.
