Hi sir, in 3 bus 2 transformer and 2 generator system, when we make the value of reactance of generator and transformer to Zero, what will we expect from the magnitude of fault current? The system is bolted SGL fault applied. Thanks!
Hello Emin, we apologize for taking a while to respond. From what we have gathered from your question, it is about the effect of reactance on magnitude of fault current. Let’s consider two cases for explanation 1. Case 1 (reactance = impedance): If this is the case, then the fault current would theoretically be equal to infinity. However, the impedance can never be zero in an electrical network. 2. Case 2 (the network only comprises resistance) It is impossible for this scenario to occur in an AC system, like the case discussed earlier. However, if we indulge this thought and assume that the network impedance comprises only of resistance than the fault current decaying exponential (DC component) will not exist as well as the higher symmetrical AC current/AC decay rate observed during the transient period. This means that the fault current would just be a uniform symmetrical waveform with the same RMS value for the entire period. Moreover, the overall impedance would decrease due to absence of reactance which would mean increase in overall symmetrical fault current.
@@Generalpac Hi, thanks for replying to my question. I think I don't need to refer to impedance. Because it is simple unsymmetrical SLG fault(Zf=0 bolted) and I found all negative, positive and zero sequence in this circumstance. However, I want to know, If I make my grounding reactance of transformer and generator equal to Zero, how magnitude of fault current will be effected? Am I explaining my thought well to you?
@@eminvalikhanov1245 Hello Emin, we apologize for taking a while to respond. Yes it will effect the fault current as zero sequence current will be changed. According to the given case, the grounding reactance of transformer will be considered in zero sequence impedance calculation only. While there will be no changes in positive and negative sequence impedance.
