Explain the Power Chart
The phasor diagram shown in Figure with the x and y axes added, as shown. This diagram may be converted to a 'power chart' by multiplying each phasor in the diagram by VR / Z, as shown in Figure, where Z is the impedance of the line. This shifts the diagram by the element impedance angle (ψ) and changes the units to (volts)2 / (ohms), i.e. to VA units. The 'x' and 'y' axes are then scaled directly in Watts and VAr's respectively.
For a constant VR the scale of the diagram remains fixed and the sending end voltage (VS) and load angle (δ) are readily estimated for various power and VAr flow conditions.
Disadvantages of SDR 1. Power consumption is more due to rapid switching of modes 2. Hardware design is not easy 3. Software bugs exist in the system
