Why EE – Scheme?
Capacitive Power (QC)
Real Power (PL)
Inductive Power (QL)
In order to verify proposed capacitor switching algorithm, a sample test system was employed using Matlab/Simulink. This system was run for various loads and load excursions in order to verify the suspected results.
The capacitor bank αD switching is accomplished in four steps. The capacitors are switched in as required by the predictive corrective software. This scheme will achieve near unity power factor operation resulting in power efficient utilization.
3Φ - 4wire switched Capacitor bank
100% Load With Full Correction,
Power factor = 0.96 (Minimum)
100% Load With No Correction,
Power factor = 0.84 (Minimum)
Zone 2 With No Correction,
Power factor = 0.87 (Minimum)
Zone 2 With 40% Correction,
Power factor = 0.955 (Minimum)
