摘要:

固态限流器通过在线路中串入等效阻抗实现限流，这势必对系统距离保护产生不良影响。以新型多功能固态限流器为例，分析了固态限流器接入系统对反映相间短路故障0°接线方式的影响，提出了一种消除等效限流阻抗影响的接线方式。利用PSCAD/EMTDC对比分析了采用所提出接线方式和不采用的两种情况下，系统不同位置发生相间短路故障时距离保护继电器的动作特性。仿真结果表明：所提方法消除了固态限流器对继电器测量阻抗的影响，保证了继电器动作的可靠性。

Abstract:

SSFCL limits the short-circuit fault current by adding equivalent impedance in series in line which is bound to have a negative impact on distance protection. Taking the multi-function solid state fault current limiter (MSSFCL) for an example, the impact of solid state fault current on 0° wiring mode is analyzed. And a new wiring mode for eliminating the impact of limiting impedance equivalent is proposed. The operating characteristics of the relay of distance protection under the two wiring modes are analyzed by PSCAD/EMTDC when different inter-phase short-circuit faults happen at different locations. The simulation results demonstrate that the proposed new wiring mode can effectively eliminate the impact of limiting reactance on measured impedance and ensure the reliability of the relay action.

Key words: SSFCL distance protection inter-phase short circuit wiring mode measured impedance
