摘要
固定串补电容对工频故障分量继电保护有一定的影响。按K(Zzd-Xc)整定保护范围时,故障分量距离元件可用于快速切除近端故障,对于远区故障,拒动、误动均有可能。当串补电容的容抗小于系统电源的正序阻抗(含短路点至电源的正序线路阻抗)时,故障分量方向继电器可用于串补线路。
Fixed series capacitor (FSC ) has some effects on fault component protective relaying. The fault component distance relay can be used to trip close fault rapidly when its protection range is set with K (Zzd-Xc). however. In the case of remote fault. its operation is indefinite. The study shows that if the capacitive reactance of fixed series capacitor is less than the system power source's positive sequence impedance. the fault component direction relay can be used in line with FSC.
