The capacitor power necessary for this compensation is calculated as follows: Qc = P · (tan φ1 – tan φ2) Compensation reduces the transmitted apparent power S (see Figure 3). Ohmic transmission losses decrease by the square of the currents.
For compensation to cos φ = 0.9, a capacitor power of approximately 50 % of the active power is required: Qc = 0.5 · P In infrastructural projects (offices, schools, etc.), the following applies: Qc = 0.1 to 0.2 · P For installations which are already running, the required capacitor power can be determined by measuring.
For each step power rating (physical or electrical) to be provided in the capacitor bank, calculate the resonance harmonic orders: where S is the short-circuit power at the capacitor bank connection point, and Q is the power rating for the step concerned.
Take measurements over a significant period (minimum one week) of the voltages, currents, power factor, level of harmonics (individual and global THD-U/THD-I). Size the capacitor bank appropriately for its reactive energy compensation requirements, based on these measurements and your electricity bills.
In single compensation, the capacitors are directly connected to the terminals of the individual power consumers and switched on together with them via a common switching device. Here, the capacitor power must be precisely adjusted to the respective consumers. Single compensation is frequently used for induction motors (Figure 4).
