Do shunt capacitors improve voltage profile?

The effect of varying the loads’ power factor is also studied and concluded that worsening the loads’ power factor will increase the effect of series capacitor in improving the voltage profile while shunt capacitors provide an almost constant voltage improvement.

How to determine reactive power flow in shunt capacitors?

Total reactive power flow in shunt capacitors was assessed by considering odd order harmonics between 3 and 15 in the substation voltage. The level of distortion for individual harmonic orders was assumed at 3% of the fundamental, which is the permissible cut-off limit for medium voltage distribution systems as per IEEE-519-1992 Standard .

What causes a shunt capacitor to overvoltage?

For a shunt capacitor designed to compensate only fundamental frequency current, flow of non-fundamental reactive power through it due to distorted substation voltage may lead to its misapplication, which can further cause large in-rush currents and transient over-voltages due to capacitor switching actions .
