Customer ServiceThere are different methods for determining capacitor size and location. The most common method (intuitive) is based on rules of thumb followed by running multiple load flow studies for fine-tuning the size and location. This method may not yield the optimal solution and can be very time consuming and impractical for large systems.
The second method is to use the ETAP Optimal Power Flow (OPF) program to optimize the capacitor sizes based on the candidate locations selected by the engineer. This method requires per-selected locations, since OPF can optimize the capacitor sizes but not the locations.
For P.F Correction The following power factor correction chart can be used to easily find the right size of capacitor bank for desired power factor improvement. For example, if you need to improve the existing power factor from 0.6 to 0.98, just look at the multiplier for both figures in the table which is 1.030.
Secondary considerations are harmonics and switching transients. There are different methods for determining capacitor size and location. The most common method (intuitive) is based on rules of thumb followed by running multiple load flow studies for fine-tuning the size and location.
