Switched vs. Fixed Capacitor Bank

Switched vs. Fixed Capacitor Bank

Switched vs. Fixed Capacitor Bank

(OP)
I am studying distribution feeders that have both load and generation existing on them. I am wondering what are the values of having switched capacitor banks installed on this feeder vs. the values of having fixed capacitor banks installed on this feeder? Also how would you determine whether the capacitor banks should be fixed or switched?

RE: Switched vs. Fixed Capacitor Bank

Switched capacitors provide the luxury of only being in service when needed.

A feeder with a high ratio of peak to minimum loading will have very different current, VAR, and voltage needs at different times.

A fixed cap bank installed to help prop up minimum line voltage (by minimizing 'VAR flow') may be far too large for light load conditions (or all-generators ON conditions) and could result in line voltages HIGHER than the maximum standard.

RE: Switched vs. Fixed Capacitor Bank

Less maintenance and fewer power quality issues with fixed.
