Ee551 Spring 2020project 3 Due Monday 31 August 2020 Explain the difference between True power factor, Displacement power factor, and Distortion power factor. Draw waveforms of the four cases below and state what is the True pf in each case: Displacement pf = 1 and Distortion pf = 1 Displacement pf < 1 and Distortion pf = 1 Displacement pf = 1 and Distortion pf < 1 Displacement pf < 1 and Distortion pf < 1 Write the equation defining Total Harmonic Distortion of Voltage (THDv) and Current (THDi), explain them, and describe what they indicate about power quality. Explain and briefly summarize the application of IEEE standard 519 for harmonic limits in electric power systems. Simulate a three-phase six-pulse Voltage Source Converter (VSC) operating as a rectifier and feeding a resistive DC load of 1MW at 10kV DC. The rectifier is supplied from the secondary side of a three-phase 1.5MW, 33/11kV, delta-wye transformer with a short circuit level of 200 MVA and an X/R ratio of 10. The transformer's primary side is fed from an ideal 50Hz, 33kV, 3 MVA generator through a feeder with impedance 0.1 + j0.6 Ω per phase. Plot the transformer secondary side line currents and voltages for all three phases. Plot the harmonic spectrum of the transformer secondary side line currents. Determine the Total Harmonic Distortion of the secondary line currents (THDi). Place a three-phase grounded wye harmonic series LC filter (between the transformer and the rectifier) to filter out the 5th and 7th harmonics generated by the converter. Assume the filter capacitors provide a reactive power of 0.4 MVars per phase. With the filter in place, plot the rectifier input line currents and the transformer secondary side line currents for all three phases. Plot the harmonic spectrum of the rectifier input line currents and the transformer secondary side line currents with the filter installed.
