    • A transformer-less static synchronous series compensator (SSSC) for an AC electrical power transmission system having a transmission line carrying an AC current and a method for protection against electrical damage are provided. The transformer-less SSSC including: a voltage source converter (100) having a DC input and an AC output and being configured to generate an alternating voltage with controllable magnitude and controllable phase angle across the AC output, the AC output being configured to inject the generated alternating voltage into a phase of the transmission line; a filter circuit (101) being arranged coupled with the voltage source converter (100) in parallel across the AC output of the voltage source converter (100); a bypass circuit (102); and an electrical current limiting circuit (103) being coupled with the bypass circuit (102) in series; wherein: the series-coupled current bypass circuit (102) and electrical current limiting circuit (103) are coupled with a first capacitive element (1011) of the filter circuit (101) in parallel. The transient nature of the electrical current limiting circuit (103) will limit the increase in the current flowing through the thyristor of the bypass circuit (102) thus limit the current peak when the bypass circuit (102) is switched on. Consequently, the current limiting circuit (103) acts like limiting the current transients generated from the influences of both of the line fault current and the discharging current.
    • 提供了一种用于具有承载AC电流的传输线的AC电力传输系统的无变压器静态同步串联补偿器(SSSC)和用于防止电气损坏的方法。 该无变压器SSSC包括:具有DC输入和AC输出的电压源转换器(100),并且被配置为产生跨越AC输出的可控幅度和可控相位角的交流电压,AC输出被配置为将 产生交流电压进入传输线的相位; 滤波器电路(101)与电压源转换器(100)并联布置在电压源转换器(100)的AC输出端; 旁路电路(102); 和与所述旁路电路(102)串联耦合的限流电路(103); 其中:所述串联耦合电流旁路电路(102)和限流电路(103)与所述滤波电路(101)的第一电容元件(1011)并联耦合。 电流限制电路(103)的瞬时特性将限制流过旁路电路(102)的晶闸管的电流的增加,从而限制旁路电路(102)接通时的电流峰值。 因此,限流电路103的作用就是限制从线路故障电流和放电电流两者的影响产生的电流瞬变。
