A single-phase motor operating off a 400 V, 50 Hz supply is developing 10 kW with an
efficiency of 84% and a power factor of 0.7 lagging. If two similar capacitors are connected in
parallel with each other to form a capacitance bank in order to correct the power factor to unity.
a) Draw the phasor diagram based on computed branch currents; and the power triangles
before and after power factor correction.
b) Determine the capacitance required for each capacitor.
c) Verify your answers using Matlab/Simulink
- show the rms currents on the Simulink model
- Plot the instantaneous branch currents and show clearly how the phase angle between
the supply voltage and supply current changes before and after power factor
correction changes, accordingly.
