Abstract
A shunt active power filter is widely accepted a solution for mitigation of current harmonics at Point of Common
Coupling in the distribution system. The performance of shunt active power filter as a device depends largely on the
current control technique applied. This paper focuses on the evaluation of current control technique with the
utilization of converter voltage vector for improved performance. To reduce the burden on the controller due to
complex current control technique, a direct power control algorithm is developed. The algorithm eliminates the need
for precise information of voltage vector and coordinate transformation which is associated with conventional
current control techniques. These methods are evaluated using RT-LAB OP 4500 real-time simulator which
simulates the shunt active power filter in real time. A 5 kVA laboratory prototype is developed and tested with OP
4500 as a rapid control prototyping platform. The performance of the algorithm is evaluated under different
conditions and is tested for suitability under unbalanced line voltages.
