Capacitor
A device consisting essentially of two electrodes separated by a dielectric. IEC 60050.
Capacitor in PSP-UFU
The capacitor element usually represents a shunt capacitor bank in the PSP-UFU circuit.
A series arrangement of a line without shunt susceptances, a bus, and a capacitor can be used to create a passive filter in harmonic studies.
In future versions, a passive filter element will be implemented in PSP-UFU.
Capacitors and reactors require only their reactive power as a parameter.
These passive elements are only inserted into the admittance matrix, and their impedance is calculated from their nominal power and voltage.
Capacitor editing form
The figure below shows the capacitor data insertion/editing form:

Besides the single general context, the "Stability" button can be seen in the lower-left corner of the form.
This form, common to several other elements, allows the insertion and/or removal of the capacitor during the stability study.

- General
- Stability Button
Name
Electrical element identification. Any number of characters can be entered using the Unicode standard.
All PSP-UFU power components have this field.
Reactive power
Capacitors and reactors only require their reactive power as a parameter, entered in Mvar, kvar, var, or (in the system base power).
The "Stability" button opens a form, common to several other elements, that allows the insertion and/or removal of the transformer during the stability study.
In this form, a generic list of insertions and removals over time can be created, customized by a switching properties context where the switching type (insertion or removal) and the event time (in seconds) are edited.
These properties are added to or removed from the list using the "Add" and "Remove" buttons, respectively.
