Installation of series Capacitor Bank in Transmission Lines.
Installation of series Capacitor Bank in Transmission Lines.
(OP)
Hello,
Am Baxter from Malawi working with ESCOM. I do load flow studies for the utility. We usually have low voltage profile in the Northern part since all generating plants are in the Southern region. Is installing series capacitors in the transmission lines a better solution to voltage problems? If Yes would you please help me with the specification for the capacitor on 132kV transmission line. Thanks in advance.

Probably, for the subject you have in your hand, you may certainly need to perform additional studies, other than simple load flow study.

Approach any reputed supplier/manufacturer of the series capacitors. They would provide you some basic information, from where you should be able to move forward.

Moreover, if you install the series caps near turbine generators, you run the risk of having sub-synchronous resonance or torsional oscillation problems. You're probably better off using standard shunt compensation at the far end / northern part of the line. Or if you have cash, then an SVC would give you better voltage control across different operating points.

which are the characteristics of the 132 kV line (length, conductor cross section, positive sequence impedance and capacitance)?
132 kV lines are often equipped with small conductors, so that the resistive voltage drop is not neglibile if compared to inductive voltage drop. If the voltage drops is mainly resistive series and shunt capacitors will not give you much benefits.
