- Week 8 Video Lecture – Power Factor Correction
- Consider the circuit demonstrated in this week’s presentation. Analyze the circuit to determine the following (include both polar and complex forms where applicable):
- Zeq
- IT
- IR1
- IL1
- Real Power (Watts)
- Reactive Power (VARs)
- Apparent Power (Vas)
- Power Factor
- Construct the circuit in MultiSIM and run a Single Frequency Analysis to confirm your calculations for the phasor values in part 2. Capture a screenshot of the analysis for both Magnitude/Phase (polar) and Real/Imaginary (complex). Create a table with your expected and measured results.
- Measure the real power of the circuit and the power factor using a watt meter. Capture a screenshot of the watt meter readings.
- Based upon the power factor, determine the value of the capacitors needed in each case to bring the power factor to the following values. Be sure to show your calculations.
- Power Factor = 0.85
- Power Factor = 0.95
- Power Factor = 1.00
- Insert each of the capacitor values found in step 5 into the circuit one at time and confirm the power factor correction with a watt meter. Use a 5% tolerance for the capacitors. Capture a screenshot of the watt meter for each case. Create a table of expected and measured results. Comment on how well the desired power factor was achieved and any reasons for discrepancies.
