Objective of compensation is to achieve stable operation when negative feedback is applied around the op amp. Miller - Use of a capacitor feeding back around a high-gain, inverting stage. Miller capacitor only Miller capacitor with an unity-gain buffer to block the forward path through the compensation capacitor. Can eliminate the RHP zero.
Fixed capacitors provide a constant level of compensation, while switched capacitors can be turned on or off as needed to adjust the level of compensation. TCRs can provide continuous and adjustable series compensation by using thyristors to control the flow of current through the reactor.
A review of shunt capacitors can be an extension of current work. Series-capacitor compensation is emerging as a stabilising tool in series compensation and phase shifting FACTS devices. Other applications include series power filters and large motor soft starting schemes.
The series capacitor is used in long transmission lines in order to compensate the line reactance, decrease voltage drop and control the line flow. However, a constant capacitor arises practical problems such as SSR.
The shunt capacitors are better in different things specially power factor correction, reactive power support and economics. However, series capacitors can have another area such as controlling the voltage at the point of common coupling. Individually, such as unbalanced background voltage distortion and blocking harmonics strategies.
