Abstract —
Short circuit fault as one of the characteristics of transient disturbances in electric power systems that must be addressed by the safety equipment. The increase at occurrence of short circuit generates large electrical currents and at a very low voltage. This research will address the simulation of short circuit interruption in the 150 kV transmission line system. The method is used to perform the simulation with the help of PSCAD / EMTDC and PWS (Power World Simulator) software’s to obtain the characteristic of current and voltage on the 150 kV transmission network system in South Sulawesi. This discussion aims to examine the changes in current and voltage during short circuit fault with or without fault impedance and fault location distance. In this case, it will be taken case of short circuit between the air ducts with Bus PKEP to PPARE , For a distance fault of 22.5 km obtained by the fault current from the bus PKEP biggest , while at a distance of 66.5 km is acquired the fault current of the largest from the bus PPARE, of four types of errors are
analyzed on the Z = 0 ohm is the largest short circuit interruption occurs in three phase fault (LLL), while at Z = 10 ohm = 15 ohm Z of the biggest mistakes of the line shortcircuit line to ground faults (LLG)
Keywords: PSCAD/EMTDC , PWS , Fault Analysis
CONCLUSION
For short circuit fault with impedance Z = 0, the fault tends to electrical current higher than the short circuit fault using impedance Z = 10 ohm and Z =15 ohm, this is due to the absence of resistance to the flow of electric short circuit fault. The interference voltage at Z = 15 Ohm tends to be greater than the voltage at Z = 0 ohm impedance and Z = 10 Ohm, this is due to large resistance causes a very small electric current flows so that the voltage is higher. For a distance fault of 22.5 km obtained by the fault current from the biggest bus PKEP, while at a distance of 66.5 km, it is acquired by the fault current of the largest from the bus PPARE, four types of errors are analyzed in which the Z = 0 ohm is the largest short circuit interruption occurs in three phase fault (LLL). While at Z = 10 ohm = 15 ohm Z, the biggest mistakes of the line short-circuit line is ground faults (LLG).
