摘要: Current distance relay is accommodated with Power Swing Blocking (PSB) scheme. However, this blocking scheme prove to vulnerable operation as it could block the trip signals if symmetrical fault occur during power swing. Hence, important develop proper detection swing avoid such undesirable circumstances. This paper presents a new technique detect by using S-Transform analysis based on current, voltage, and three-phase active reactive waveform. To evaluate effectiveness of proposed technique, testing has been conducted under IEEE 9 bus test system. Simulation results show that can reliably occurring
