Curtin University Department of Electrical and Computer Engineering Electrical Power Transmission and Distribution ELEN4001/ELEN6010 Lab Report: Fault level Calculation using Power World Simulator Due date: 22 October, 2018 4:00 pm Students should hand in their assignment with cover sheet to the assignments office (204- Level 2) on or before the due date Figure 1 shows a single line diagram of a five-bus power system. Input data are given in Tables 1, 2 and 3. Bus 1 is assumed to be a swing bus. Figure 1 Single-line diagram for a five-bus system Table 1. Synchronous machine data Table 2. Line data Table 3. Transformer data Using Power world Simulator, plot the variation in the phase a, b and c voltage magnitudes during a single line-to-ground fault (phase a to ground) at bus 1 as the fault reactance is varied from 0 to 2 pu in 0.25 pu steps and fill in the following table. Fault Reactance (pu) Va (pu) Vb (pu) Vc (pu) 0 0.25 0.5 0.75 1 1.25 1.5 1.75 2 Hints: -PowerWorld Simulator computes the symmetrical fault current at any faulty bus in the system. -For any type of faults, the Simulator also computes bus voltages and contributions to the fault current from transmission lines and transformers connected to the faulty bus. -Along with components data shown in the tables above, the pre-fault voltage and fault impedance must be identified in the input data. -The simulator computes but does not show the zero, +ve and –ve sequence bus impedance matrices by inverting the corresponding bus admittance matrices. -Then the software calculates the sequence fault currents and voltages at each bus during the fault. These sequence components are then transformed to the phase domain. -Output data for the fault type and fault impedance selected by the user consist of the fault current in each phase, contributions to the fault current from each branch connected to the fault bus for each phase and the line to ground voltage at each bus.
