Answer Posted / Akif Shabbir
We typically do not use an equivalent voltage source in a negative sequence equivalent circuit because it can lead to complex and unstable calculations. Negative sequence voltages do not have physical significance, and representing them with a voltage source can create mathematical difficulties when solving power system stability problems. Instead, negative sequence currents are represented using current sources or Y-delta transformations, which provide more accurate and stable results.
